Does anyone have a photo of this installed? I got a NOS one in a box of parts and the directions are a little vague. Thanks.
-
Is that for the rear?
-
The package says , Rear Int'l 51mm Standard. For aluminum swingarms only.
-
Can you post a picture of the adapter.

I have never seen that before. Pretty cool.
I think that it will fit on the early carbon dropouts by the look of the 2 holes.
I would be happy to give it a try. ;D ;D ;D

Damn! Wish my little mill was cnc, I'd be burning out copies.

Nice. My nephew is a die machinist, part owner even. He made me an adapter in the past. If you want to lend it for a week, I can see if he might be willing to program it in and crank out a few.

We should be able to make that happen.

I will contact Mike, my nephew, and see if he will do it. He has a bit of our blood as he owns a disco monkey though a bit dusty. Will this fit the

Ah, the old 5996 - nice to see one again - ;D
Proflex was well ahead of itself when it designed these little units so all of us could eventually upgrade to rear discs.
Much discussion went on a ways back as to who created and came up with the idea for rear adapters for the old proflexes -
I'd always referenced the 5996 as the original and that our plates were loose copies of the original design.
I couldn't get one at the time as they were discontinued so I hacked a few out in my garage and they came out looking like this:

It would be nice if someone with the right knowhow and machinery could reproduce them - they look sharp

I have two 857 frames with carbon swingarms. If this can fit, and if it can be duplicated, I would definitely be in for two of them.
-
Does anyone have a photo of this installed? I got a NOS one in a box of parts and the directions are a little vague. Thanks.
Here you go, it's very sturdy since it's machined with the oval to fit in the dropout. This is on my aluminum swing arm 4000. Very Simple install.

Thanks you glader60. Makes much more sense now.
-
Now one of those on the rear of my 857 would be ideal :)

My nephew machinist says he is too busy to make any for now. He recently became part owner of the company. I will keep on him though.

i would like one of these parts please, please can anyone make that happen?
-
i would really like to find this part. i could probably break out my dremmel, but the actual part would just be so much nicer.
-
Your quickest solution will be to make your own adapter. Plenty of people have done this succesfully. Alternatively my 957 has HOPE Ti Glide hubs with their hanger system that puts the hanger inboard of the swing arm and locates onto the wheel spindle. Im sure there are manufacturers that still make this type of system.
How ever if you do find a 5996 then make some copies as their are a lot of other members of this site who would also like one.

CAN DO!

hey, is it possible since you have the actual part, that you could measure the mounting holes since all i have is a photo and the drop-out. i know the drop-out holes measure 51mm to each other, but how about you triangulating the brake adapter holes to the drop-out holes and post those measurments, if you can. thank you. i've got a chunk of al in 1 hand and my dremmell in the other

OP
only problem with this piece is that it is flat and doesnt fit into the drop-out oval
-
if anyone is interested i did find a shop here in arizona that can take these photos and build a program to produce copies of the actual part #5996. the more parts made, the cheaper they are for all of us. im not looking to make a dime on anything here, only to put my hayes disc on my bike. so the first part w/ the program would cost $100.00 or less USD. closer to 75 but depends on the fitment into the drop-out oval and how long it would take to get the fit correct. after the first one each additional part could be 20 bucks or less to produce. so what i need to know is how many of you guys are interested.
david
-
the way i see it is if 10 of you could pay $30.00 each for a completed part, then have 11 parts made, would be the same price for my part. the fitment could be scrutinized on my bike with 160mm rotor for proper alignment. mine is a 1999 k2 evo 1000 aluminum swingarm with the 51mm spacing 2 threaded holes in the drop-out. let me know. i already have the brakes and disc hubs, so im ready to roll right now.
david
-
and subsequenty, producing only five parts would cost roughly 50 bucks a piece. i do have a paypal account. and can ship these pieces to anywhere, im willing if you are.
david
-
I'm in the UK and own some of the last "Hammerhead" adaptors, but would be interested in a #5996 "Clone" as I agree it would probably fit better and doesn't affect the skewer fitment.
But the problem for us in the UK is import duty (~20%) and more importantly the excessive fee (~£9) to collect it!
but if an item is below £18 then it's waived, so on todays exchange rates I make that $28
So bottom line for me is, that is I where I can buy into this program!
Good Man!
Let us know!

Sorry gents to come straight into to this one as it is my first post but this is exciting for me I would love to have a bracket for my swingarm so count me in.
-
thanx for the response. i to am very excited. i'm taking my bike and the photo's from this forum in to PRECISION POWDER COATING AND MACHINE today to get him started. it sounds like he can take the photos and my drop-out and produce a 3-D virtual prototype. ill post photos of the first piece when its installed and working, then we can go from there. if we can get enough people in on this im sure we could get the price under 20 bucks a piece. USD, which sounds like it would do the job just right for those in the UK. again thanx for the support.
david
-
what would really help i think would be to get measurements off an actual part. like an x pattern from the 4 mounting holes, ie, measure from the bottom dropout hole to the top brake adapter hole and vise versa.
david
-
hello, everyone. so, here's the story. unless i hear from thunderchild or ironhorse/k2 buy monday afternoon, with an actual part for me to have copied, i'm going forward with duplicating this part at the facilty here in prescott az with the pictures and my bike with all the other pieces in place to design and produce the first part. that could cost up to a hundred bucks for me, hopefully not, but if so, oh well. it will be worth it. after that like i said i'll test it to make sure it works, then i will post pictures here. then making copies of the part obviously gets cheaper by the quantity. it will have to be fair though, i dont want to pay that kind of money and do the leg work, only to ship out copies to anyone for a lot less than i paid. so i will keep you posted on the initiall cost. if i could get the part from thunderchild or k2 then it would be cheaper initially to reproduce it as oposed to copying a photo and taking all the measurements and test fitting untill it was right. as far as shipping to the uk, if i remember correctly if you pay me through paypal, it doesnt matter what for. hte item i would ship is so small it could be done through the post office in a bubble envelope marked as a gift. the amount piad for the part and the shipping of the part are totally seperate from each other. in other words if i have three parts made, and it cost one hundred fifty dollars to make them, then we each have to pay fifty dollars. i'm not complaining, i'll do the first part with or without any additional help either way. but if there are people out there interested you should speak-up
-
Yes I am interested it sounds fair to me count me in I have pay pal so no problem at all and the idea of sending here to the Uk as a gift is spot on ;)

Just to clarify, I dont have a 5996. The system on my 957 is Hope's own system that will fit any bike. However, Ive contacted Hope and they no longer make it.

i'm having trouble trying to upload a photo, i spent a couple hours last night in my kitchen with a dremmell and a piece of acrylic and came up with a perfect prototype for the brake adapter. i am totally amazed with myself because i had never done this before. the part fits perfectly and even on the first attempt. so i took the prototype to the machinist this morning and a CNC'D part should be ready by tomarrow afternoon. even the machinist was amazed at the accuracy of the part i made. it doesn't look exactly like the 5996 but it does look pretty good. it will be a little thicker i think than the 5996 but i will feel a lot better knowing for a fact that it wont fail. since i dont have the actual part # 5996 i went with "better safe than sorry" attitude. i will keep you posted. and could someone please tell ne how to get my photo's up here.

david

You should be proud of your handywork, thats a top job youve done.
Chris
-
thank you, i made a couple of changes to it right before i took it to the machinist today. it will be cool. i cant wait.
david
-
by the way the reason for the prototype, simple. i learned something this week, to have a shop design and produce even a small part like this one, even with photo's and my bike, the cost would be $85.00 per hour, and that adds up very quickly. it could take 4 to 8 hours to finsh just 1 prototype. so i started. i dont have that kind of money. ( money can be one hell of a motivator). now with my prototype in their hand, the most this first one will be is that $85.00. that is scanning it into the computer entering the cutting program then setting the cnc machine and milling. he said it should take about 45 minutes, i hour at most, hence the $85.00 cost. then like i said before, the more copies, the cheaper they become. but only as long as the copies are made at the same time. if i call him a few days later asking for 1 copy, it will cost roughly 75 bucks. if i say 10 copies, it will be roughly $125.00 for all 10. making those cost $12.50 each. hopefully there are more than just three of us interested. if not we are looking at 60 to 75 bucks each. i am paying him 85 dollars when i pick up the first 1. i may put 1 up on ebay to see if there is any interest.
david

This is great keep up the good work I am assuming this will fit the carbon swingarm I have on the 4000? i'm sure the end drop outs are the same. looking forward to the finished item. By the way did the bike come with those forks as standard? I am running crosslinks but am thinking of changing out to something like those
-
ah - - - the ever evolving add-on disc adapter for our old Proflexes - - - you gotta love it.
I'm not an engineer, glad some of you younger guys are or at least have the wherewithall's to figure it out -

i wish i was a younger guy, 49. buts thanx for the vote of confidence

the fork is a 2004 marzocchi bomber mx comp 80mm travel, liquid smooth. nothing like the fork that came on the bike new. as far as the drop-out, i would think the sape would be the same, however i have not measured the 2 for differences, only mine

I'm only new to the world of Proflex, picked up a black 1000 that i want to restore but would be in for an adaptor. Can you send to OZ will pay postage.

by the way, i too am new to the world of K2, this is my first. always been a hardtail cannondale fan. but i do really like this bike. i have plans to powder coat the swingarm gloss black and the triangle bright yellow this winter. i just started looking for black K2 logo decals. will probably have those made. i'm too old to go flying down mountain sides anymore, and not crazy enough to go flying off stuff i used to. but i love a nice smooth comfortable american made bike that looks cool riding around the small-ish town i live.

just a thought
-
This is what I get for not checking the forum for a few months. I'm in as long as it doesn't say K2 on it.:D
BTW, lets talk carbon swing arms. Didn't the guys in England run into problems with heat dissipation in their adapters? Especially in the carbon swing arms?
Thanks,
Rich
-
I'm new to the k2 scene, I don't know about the cf swingarm. I'm on aluminum. I thought the cf was bonded to an aluminum dropout. And k2 was just an idea. I have a few drawings. Could just do the oval like the original. Could do flames. Whatever u guys vote on. Mine will be up tomarrow if all goes well, and It's different then that. U guys will vote and then I'm going to have at least 5 more made by next week.

Oh no worries, I was hoping those that have been here a while could chime in on the CF swing arm thing. You are right, they are bonded.
I am from New England and it was really cool have a brand, that being ProFlex, taking it the big boys on the wet coast. Then K2 bought them out, moved them to the west coast and within just a few years that was that. The first thing I did with my 5500 was peel the K2 decals off. But, that's just me. I also like my Cross Link, so you can see I'm one of those people. :D
But a design would be really cool!
-
If heat dissipation is a problem for the carbon bonding, then perhaps you could design a heat sink into the adaptor.
-
way ahead of you. One of the drafts has a heatsink designed into it. This first part will b done tomarrow morning. It looks pretty cool but the next 4 parts can be different. I say 4 because I have heard from 4 of you so far. The machinist is going out of town for a few days and will be back next Tuesday. He will make the 4 parts next week. I will need to collect $50.00 US dollars plus 6 to 9 dollars shipping cost from everyone to my paypal account before those parts can be made. A photo of mine that I just paid $ 90.00 bucks for should be posted here by tomarrow night. Then give me a thumbs up and I will message you my paypal info. I actually had a machines part in my hand 3 hours ago, but it was off a little on fitting my bike. I am paying a lot of money and spent a lot of time designing. I want it right.
-
I'm definitely gonna need one with a heat sink then. How embarrassing would it be to have your carbon swing-arm come unbonded on the trail. :D I won't be upgrading to disc any time soon, but having the mount means that I can.
-
the sketches i've made incorperating some kind of heatsink are UGLY.

Nice!

i think this is a duplicate post, but here it is, a working prototype. i am 250 pounds and the brakes are very strong. the pads and caliper are centered on the rotor and the side play adjustment is perfectly centered, when i spin the wheel there is no rubbing. i can have the first five or six copies made after receiving the money from you guys on paypal. the price $50.00 US dollars plus $6.00 to US residents and $9.00 to most other countries can be paid to JOEROCKET69@YAHOO.COM. DAVID NAPOLEON. the price can go down if there are more than just 5 orders paid. by the way this is rough looking because this is the part we have been fitting, the final part will look much better. the design on the face can be different but the price increases with each change that we make. for this part the final program is written and ready to reproduce now.
-
by the way i will include the correct size button head screws for mounting this part to your drop-out. remember to use threadlock, (blue)
-
also just in case, I AM NOT AN ENGINEER, NOR AM I A MANUFACTURER. i am just a guy who milled out a piece of plastic and took it to a CNC shop to produce a working part. while this part is made from billet 6061 t6 aluminum, there can not be any warranty, period. i am using the exact same part you are purchasing, i am taking the same risk in using this part that you are. it looks and feels like it will outlast the frame it's bolted to. you may have to file alittle here or there, maybe not, i dont know. but this one fits nice and tidy. so please READ this and UNDERSTAND it's intent before buying this part.
sorry but it has to be said
-
Are you a Nicky Hayden fan? Simple is fine with me. Are there holes pre-drilled in your drop out?
-
nice, someone who gets my email address. yes, yes i am. moto gp in general but a big nicky fan, since his ama days. and yes my drop-out has holes drilled and tapped, 5mm i think.
-

i believe it will take alot more heat to unbond your drop-out than this set-up is capable of. you would have to ride the rear brake down a mountain road miles long to generate that kind of heat. the whole surface of this part is somewhat of a heatsink. the heat would have to travel from the pads to the piston heads, to the caliper, then the adapter, then this adapter, then the drop-out.
-
I was thinking the size of that adapter is such that it would make for a pretty darn good heat sink.

I agree
-
So no one yet? These are ready to order. If 10 people order then I can always refund some money. I'm not going into bussiness here. I spent 90 bucks on mine. I am not trying to make a profit.I went hauling but down my hill about a mile riding the rear brake to check for heat. Rotor was hot but the part was literally very cool. I know it works.
-
and incase anyone is wondering, I can't aford to go and pay 200 bucks to have 4 copies made. or 250 for 6 and so on I think its 350 for 10. I need your money to order these. Sorry. You don't know me from adam, but I didn't go through all of this to scam anyone. just trying to help.
-
I guess I could put them on ebay so your purchase is guarantied but then those in UK have to pay somekind of premium from what I understand, I coudnt ship as a gift. Also you would have to give me 5 to 9 days to ship so they can be made at the same time, but the same is true without ebay. They have to be made together or they are 90 a piece. Let me know how you want to do this. Also ebay charges 10% so add that to the price. I can't afford to lose money on this.
-
paypal is 3% but that's only a couple of bucks. I figured that into the 50 plus shipping price

Wow - well done.
I might be interested - - - and I don't even need one.
Wonder how those holes line up on a non drilled/tapped dropout such as on an Oz/5500?
(drilling and tapping your only good dropout can be a little nerve wracking)
One would probably have to assemble the unit, clamp it to the rotor then wheel forward, mark then drill

I maybe in for one of these. I got a CF swing arm

actually the pictures dont show it but this piece is totally machined out on the back side to fit into the oval perfectly, becoming flush to the back of the drop-out. its really very nice. it was a lot of work geting that right with my dremmell on the piece of plastic that i took to the machinist. i probably should have taken a picture of that before mounting it. anyway you shoulb be able to clamp it into the drop-out and mark the holes mark the holes, everything should line up perfect after that

here is what it looks like from the back

so like the k2 part it uses the drop-out for its strength. the 2 bolts just hold it into place

now that ironhorse baught k2 i wouldn't doubt the same fate for k2, gone in just a few years

Firstly thats an awesome bit of work youve done getting that made.
How ever it looks to me that your metal swing arm has a different shape drop out to my carbon 4000. Your drop out has more defined angles and looks more like the one on my 857, which insidently all have pre drilled holes for disc mounts. It also looks as if your dropout is built up slightly around the area where the top hole is for the M6 bolt, or is it a shadow? That bolt is very close to the edge of the drop out. The carbon swing arms dont have any extra metal here so its possible the hole in your bracket might not line up with the dropout on the carbon arm. As you will have to drill your own holes in the carbon arm drop out you could end up with the hole breaking out of the top of the drop out. It might be nothing but I thought I'd mention it.
Can I suggest you post your mock up to some one with a carbon 4000/OZ type arm to see if it fits? Im in UK but would be happy to help?
If it turns out your adapter fits the 857 carbon arm you could have struck gold as that is probably the most wanted adapter of them all.
Ive lined up a 4000/OZ Hammerhead with a 857 tonight and theres a big difference, the holes are about 10mm further apart. But theres nothing to say the holes in the Hammerhead are where K2 would have drilled them. And the more I look at it the carbon arm drop out is curved at the rear where yours looks straight.
These are all positive observations and not criticisms in any way.
The issue of the carbon drop outs being affected by heat tranfer was much talked about during the making of the Hammerhead adapters. To over come this they were made of a grade of stainless steal that tranfered least heat and had slots cut into them to disipate it. However as the original K2 part was made from aluminium I dont see a problem.
If we can be sure it does fit the carbon arm I will have one.
Can I suggest you design and make a crosslink disc mount next ;)
Chris
NB. I,ve just read the K2 instruction sheet from their version and it clearly says 4000(all models) so every thing I have just said could be rubbish! ha ha! it would be good to check though.
-
thank you very much. I am proud of how this turned out. but It's the smile on my face riding it now that can't be described. I designed this out of necessity though. and only 2 weeks from finding out a part was needed and mounting the finished piece. of coarse the 90 bucks as well. being new to the k2 world I have looked at the gallery of bikes on this forum and some are very cool. I however don't know what all drop-outs this part will fit. I printed a owners manual for mine two weeks ago and part 5996 was in the frame parts listing. I would think that any bike with this similar layout would work. I have not looked at the owners manuals for the other models. if you cab take a chunk of clay and mash it into your drop-out u can use that to have a part made. all I had was a photo of part #5996 a dremmel and a piece of plastic. and the thought that I wasn't going to let this beet me. I have said before I have never done this, I would need a bike to do it again. I don't know anyone else here in AZ. but I could post an add on Craigslist.

a little about me, I have had a Passion for bicycles since a kid in the early 70's. 5 or 6 years ago I met my woman and stopped riding. sold my cannodale and got fat and happy. then the heart attack came. without insurance a large bill came. so this last year I decided to find a used bike I could fix up and ride to both relive an old Passion and lose wieght. I found this bike on Craigslist for a hundred bucks and took it apart and rebuilt it. eventually I sold some of the junk off it and made my hundred back. the frame and drivetrain were great, just not the other items, so over the last few months I purchased off ebay the wasting bar, stem and post. then off ebay the hope pro 2 wheelset with mavic cm819 runs with dt butted spokes hand built but used for 375 bucks. the Hayes hydrolic brakes barely used off ebay for 78 bucks 2 weeks ago, that's when I found out I needed this part. I googled it and found this forum. back in the day 10 years ago I wanted one of these, I love the frame and swingarm
now I have one. it looks and rides so good. and only 900 bucks total. loving that old feeling again jumping off curbs and wheelies, feeling free. life is short and I'm still here.

Do we have to pay this week? Because I can't do that.
On the other hand, would you be willing to mail your plastic prototype to the shop I work at (and where I keep my 5500) so I can confirm for everyone that this will or will not work with EVO bikes?

Thanks,

-
no you don't have to pay this week. an order will be placed when I have at least 5 parts paid for. so the sooner everyone pays the sooner they get shipped. and I no longer have the plastic part. and if 5996 fits so will this. check your owners manual. print one @ k2 if u don't have one. Mine listed that part in the frame parts list
-
Mine is a '98 and it's not in my owners manual. Also, '98 5500 = OzM, so guess it won't. I did misspeak earlier as I forgot all the '99 bikes were all evos. Too bad about the plastic prototype. It'd have been a nice way to confirm things so a mess of us carbon riders could have gotten in on the action.
-
mine is a 99 EVO 1000. just got home from a brutal test ride. bombing down mountain roads and mashing on the brakes. Badass, I mean WOW.
-
I thought about keeping the plastic piece as a souvineer, but the machinist wouldn't give it up.

ok, so, i am confused. listed below are the only bikes that this part 5996 will fit. my part is based intirely on part #5996. that is how i found this forum. that is why i am posting in this thread, K2 5996. i asumed that those of you who have been questioning the fitting had already looked at the posting below. there might be significant manufacturing reasons that k2 did not design a part for your application. there are front suspension forks out there that can only use a maximum of a 6" front disc brake rotor, there design cant take the stress of something bigger. maybe the same can be said for the CF swingarms, they might not be designed to have torsional forces at the drop-out location. i dont know. i have made a pretty cool rough copy of part 5996. if anyone would like one, let me know.

looks like palm springs ca in the background. without a bike i wouldnt know where to begin. besides im no design engineer. and the part in the picture looks like it worked. do you not like that one? or is that someone elses bike?
-
i purchased disc brakes for my bike because it looked like k2 had rear disc in mind when the bike was designed. the brake cable-guide bosses that are welded to the frame were double, one for cable with stops and one without for hose to pass through. thats on the frame, the fork just has the pass through hose type. so i figured there had to be some kind of adapter. i didnt know what it was called until i printed out the owners manual.
-
that's one of my 4500's, carbon crosslink and home made adapter.
made a several of them but only mounted a few - they've all worked without issue even on the aluminum legs.
the old verbiage on the process is in the 'How To's' near the top. several have made their own and some old pics should/may be in picture galleries.
pic was somewhat close to palm springs - Irvine, CA

Yes my 4000 is a '98 model and my 4500 and OZ are technicaly the same as they use the same carbon rear arm, so Im not sure it will fit. The dropout shape looks different to me. A real shame as your finished artical looks and obviously works fantastic.
Am I right in saying all the models on the 5996 sheet have aluminium swing arms? Thats maybe where the worry over heat dispersion came from for the carbon arms.

i was looking at images on google of the 99' 4000 and it has a CF swingarm. the 5996 instructions say they work on all 99' 4000 models, so i would say no not all models that this part works on are just aluminum swingarm models. maybe k2 changed the dropouts in 99'
-
i'm betting it doesn't matter what the material of your swingarm is for this part, it's a drop-out thing. certain bikes in certain years had this drop-out, wether it was predrilled like mine or not. CF or AL. i dont know why or if or if not k2 designed similar type parts for other models.

i really do hope that some of you can use this part, but to be quite honest, helping fellow cyclists would just be icing on the cake. i am just happier than a pig in $hit. it looks like it belongs on the bike and works so well. i have been really putting it through its paces listening and feeling for anything wrong and that has just not happened.

Yes the give away is the shape of the oval hole in the dropout. In the aluminium arm it is an oval but in the CF arm it is an egg shape. The rear edge of the CF dropout then mirrors that egg shape.
Its a quality peace of kit you have made so I hope you manage to pass on a few.

actually i was thinking of a two piece design that im sure would work and look pretty cool for the CF swingarms egg shape dropout. it's only in my head, but if i had a bike i bet i could design one

There is a race on the 15th that I want to do. After that, I'll look into taking my swing arm off and mailing it to you.

I will throwdown some drawings. if they come out good enough ill post them

Your existing design would work perfectly fine if it was reshaped for the egg shape dropout . Drilling the CF arm dropout has been done successfully by many people who fitted the old hammerhead adapter so thats no problem.
-
I am getting my hopes up again :)
-
a 2 piece part unlike the other adapters that have been made, could be aluminum and be cnc machined to be key'd into each other sandwiching the drop-out using the egg shape to lock it in. while a "cooling duct" can also be machined in, making drilling and tapping the drop-out un-needed. it sounds stranger than it looks in my head. with a swingarm and my trustee dremmell though i could come up with a plastic prototype. funny too because a month ago there was someone on craigslist here selling a 4000 with the CF swingarm.

Im still in - it will fit my 98' k1000. let me know when you want the money.
so, do you still want the part? it's $90. U.S. plus $9 shipping. let me know so i can have it made.

hello, according to andy the cad designer at the cnc shop you are correct, it would be easy to take a variation of my part and adapt it to fit your drop-out as long as he has a swingarm to do it with just by canging the program that machines out the back side of the part, changing it to an egg shape for your swingarms. but you would have to drill m5 holes and tap them . he could locate the holes where there is the most material. it can be done. even after long downhill rides with brake rotor heating up this part stays cool, i dont think you guy's will find the same heat issues as you have in the past, this part has a lot of serface area and no anadizing like the k2 part.

Very Cool!
I have a ride to the race and the money, but I need new cleats and I'm not sure we are going to get them in time. Any way, I'll ship the swing arm off after that.
And I just now found some riding buddies. [sigh] Oh well, for the betterment of ProFlex's every where. :D
-
well, scratch that. a guy here locally has a 4000 with a CF swingarm for sale on Craigslist. he is willing to go with me to the cnc guy with his bike to take measurements. this may work without the need of your swingarm. I will find out. it depends on if the cnc guy needs only measurements or if he needs the ARM for a week. I will let you know
David
-
I don't want you to get your hopes up though, if its easier for the machinist to have a swingarm To keep for a week then that's what would need to be done. I don't know if this guy would be willing to leave his bike for an extended amount of time
David

No worries. Either way is fine. I promised my front fork shock set-up to someone else anyway thinking I wasn't going to have my swingarm anyway.

I am really sorry I haven't got it out to you yet. I don't own a car and all my tools are back in Maine. Getting to the shop so I can take it apart on a day that I am not subbing and not having to work there has proven quite difficult. I am working on it.

I am really sorry, but I will not be able to send it. Work has dried up the past month and I am sweating making rent. Also, I just can't seem to get to the damn shipping place (the swing arm is off). In the mean time a local MTB club just got organized that I can actually ride with, and I've missed out on over a month of Sunday's worth of riding. I am really sorry for disappointing everyone and not being able to keep my word. Maybe when in the late spring when the road rides pick back up and I have steady work again.

so i received the k2 part # 5996 in the mail friday, now i realize that a new part had to be made anyway. my part lines the caliper up perfectly to a 6" rotor, the k2 part must use a 5" or 5.5". using the stock k2 part makes my caliper run too far in towards the axle not using the outer part of the rotor. i never asked anyone who had that part what size rotor was used. so if any one out there is using the k2 part 5996 let me know what size your rotor is.
DAVID
-
The K2 part would be for 140mm rotors. But, I believe the 74mm to 51mm mount adapter you have is for 140mm rotors. There is one for 160mm rotors. So, if you ever redesign the part it would make it more universal if you adjusted the design to mimic the K2 part in that manner.
-
It's been a long time discussing the K2 Part # 5996 disc brake adaptor. I am updating my 1999 K2 4000 bike and want to upgrade the rear brake to disc. Are there any adaptors out there or any engineering specs to reproduce. I have produced a mock -up that is very close dimensionally but want to be sure before I attempt to produce the adaptor set up for 160 mm disc for Avid BB-7 disc brake assembly. I have a cousin who owns a CNC shop and would help produce this part. Any help would be appreciated.
-
The K2 5996 adapter will not work with neither carbon fiber swing arm types (4000/5000 and 857/957).
I have one and it came with a 2002 Bumpy Monkey with the cantilever aluminum swing arm.
In addition to that, the 4000/5000 carbon swing arm dropout :
a) doesn't have any threaded holes in place so that the adapter could be secured to it
b) the ellipse shaped cutout in the dropout could prove challenging to match
c) to the radius of the 'flat' part of the dropout could prove challenging to match
I have been entertaining the idea of building an adapter for quite some time but the lack of time and proper machinery proved to be an issue...
One of the idea was to actually remove the dropouts altogether and replace them with new ones machined to include and ISO mount or posts as well provision for 142 through axle etc...
-
Thanks for reply. My bike has aluminum swing arm and is tapped for an adaptor #5996. The K2 bike website has vintage drawings for the bike that go back to 1999. I have tried to find out engineering specs for reproduction, but w/o success. Hoping someone has this adaptors that is shown in previous posts.

Hi Brains Trust
Newbie here.
Thought i would raise this from the grave, as there is now 3D printing capability, which would allow for disk adaptor prototyping.
Is there any interest?
-
Hi,
I've seen your other post as well.
I was lucky enough to buy the last of the Hammerheads from Mike Billet and so I've equipped my bikes.
Mike has very kindly provided his engineering drawings on the Facebook Group and possibly on here somewhere...?
I can highly recommend them, especially if you can make them out of the exceptionally high quality Stainless or Titanium that Mike supplied to me.
The only slight worry for some people is the ability to drill and tap one or two holes accurately into your swingarm.
They work faultlessly and are a very elegant engineering solution adding minimal weight and zero "clunkiness" to your bike.
On that matter, the version you have shown in your other thread is nicely made, but strikes me as very "clunky".......
I assume that it relies on sitting on the axle, but I can't work out wether that is inboard or outboard of the swingarm either way it needs extra width on the axle which I just can't see is available?
Then I guess it just rotates until it meets the swing arm material and that is what stops it rotating...? Hopefully thats on a relatively flat and broad contact point or else all the preesure of braking is on a limited area......
and the same for the front when I would be concernes that it would damage the crossllink leg.
Not meaning to be negative, just what I would think about if I was considering this.
Col.
