simon,

are you sure these swingarms wouldn't fit an Oz? I find it hard to believe that they would have made different carbon swingarms given the cost of making molds.

but, I am sure you know way better than I do. Too bad these don't fit Oz's, I would have bought one or two.

Dennis,as Frankd3000 say's also the part numbers are completly different,15482 for an Oz 15358-A for an 857/957,
Simon.

Hey, Those are disk brake holes!

Yes, I will buy one of those. I would fit on my 957.

Are these the only ones he has? Ones without brake bosses? And without the 2 large holes at above the rear mounts?

those swing arms need main pivot bearings

they look like they do....from the pictures.

ps Terry if you ever sell your Way Big 957....just one call to me, okay? [smiley=laughing.gif]

No Chance!

But I did crash it yesterday. Just scuffed up the rear skewer. But did a Matno and tore ligaments in my left shoulder. The X-rays did confrim a fracture in my shoulder blade. Will be seeing an orthopedic specialist tomarrow, but there is little treatment but time.

I am thinking of one of these swingarms for a strut project on the 957. I was just thinking of adding disk brakes to it so I can free up the v brake mounts for a strut addition.

Guess I will have time now.

Terry,

Sorry to hear about your scuffed skewer! Dang. That stinks. Maybe we could get together and do a one-handed ride...

The real bugger is that these things are not like "regular" broken bones with 6-8 week healing times. They can take 4-6 months, and hurt the whole time. And if you're lucky, they heal completely (usually). The torn ligaments are more of a worry. Do you still have full range of motion? If so, then at least you know you have the possibility of healing without surgery (although it probably hurts like heck to move at all).

Good luck! Listen to your orthopod - don't ignore his advice like I did (I did a 60 mile road ride on Friday, at least it didn't bother my shoulder! However, my OTHER shoulder was bothering me, probably from favoring the hurt side. The real bummer is that my other shoulder has been messed up for 8 years from a swimming injury! Grrrr...)

Matt,

I think I have full range of motion, but I can't lift my arm. On Saturday I could'nt move my arm at all. Now that the swelling is going down, I can move it somewhat but not lifting. I have to use my right arm to move it around.

The ER doctor said that probably the pain from the fracture is stopping me from lifting, psycosomatically.

And I became one of those few that cannot tolerate Vicodin(or lots of it). Spent 2 hours puking yesterday before we figured that out. By evening I could eat again. FUN!

Today I feel pretty good. Have that appointment with the Othopedic specialist at noon. Will have more info then. I have to bring my ER xrays for him to reexamine.

One handed ride huh? Been thinkin of it.

Terry

Matno · « **Reply #21 on:** August 15, 2005, 06:06:08 am »

Sounds familiar. I could move mine in any direction with my other hand, even right away. But the pain was a serious limiting factor. Now that I'm almost 3 weeks out, I feel almost "normal". I can do most things without too much effort (driving, dressing, showering, etc). In fact, as of today, I can raise my arm all the way slowly (to the side/abduction, which was the most painful from the start). I've always been able to raise it straight in front, just not the side, and internal rotation was really, really painful, but getting better as well. Who knows, maybe mine wasn't as bad as I initially thought. Even so, I can tell it's not going to get well as quickly as I want it to!

I actually did go out on the 5000 last Wednesday with the Boy Scouts (I'm the scoutmaster). Had a great time, and I even cleaned a couple of big logs. The only painful part was when I subconsciously grabbed a thorny branch and tried to yank it off the side of the trail with my left arm. BAD idea. Mostly, it's those stupid reflexive actions that get me - about once a day I drop something and grab for it, which sends shooting pain through my shoulder and reminds me that I'm an idiot...

Bummer about the Vicodin. That is a rare reaction. I was actually wondering how anyone could get hooked on the stuff. It's a commonly abused drug, but it literally has NO high or anything like that. Works well for pain, but the main known side effect is dizziness (and I assume you know, accompanying nausea). Good luck!

I just emailed you at edwin.calip@us.army.mil. JINDER is my name.

I want one please....

Frankd3000 · « **Reply #23 on:** August 15, 2005, 02:05:48 pm »

NO NO NO! GUYS, those two holes in the left drop-out are NOT the right spacing to bolt up a disc mount and go!!!! The spacing of those two 5mm holes is ONLY 45mm, not enough for what's needed.

You can use those holes as a mounting point if you wanna make your own adaptor. Trust me on this, i'm in the middle of it right now.

However, think of the possibility of what you can run in tire size if you were to mount a disc on the rear and remove the v-brake posts. [smiley=nod.gif] Anyone know how to remove those? Just drill/grind the rivets???

The non-strut crowd is now envious. [smiley=laughing.gif] Okay, well, only maybe. (shrug)

Terry - very sorry to hear about your shoulder. Hey, time off now, right?

shovelon · « **Reply #24 on:** August 15, 2005, 03:48:57 pm »

Hi there Andrew,

So what the heck are those holes for? I see that there is a curve below the top hole, so there is a mount up issue. I remember that Merlin bikes were using these swingarms, maybe they were destined for them?

No time off except from riding. The Orthopedic specialist says I got lucky. The fracture does extend into the socket but is a 3 to 4 week healer. And the swelling is going down, so I can move it better.

Matno, Scoutmaster huh? Say hello to ASM Troop 118! I do the Cycling and Citizenship merit badges. Am a specialist in Ultralight fastpacking, and been to Philmont in '04. Junior just got back from his second, and became Eagle in '05. Scouting career is winding down now that all my cubbies are turning 18. Six of my original bobcats made Eagle(just before 18 I might add)! Good times eh!

The damage to my ligaments is minimal. I can rotate in all directions but the Doc wants me to keep immobile for 3 to 4 weeks while doing some moving but not lifting. We tracked the fracture into the socket so that is where the pain comes from. In 4 weeks I see my Primary care Physician for followup and maybe phys therapy(not). Said I can drive or do anything I want that does not cause pain. Should be out and about soon.

Take it easy,

Terry

I don't have a clue, Terry. When I first saw them and started reading about disc brakes I figured they were for discs using the pre-ISO mounting size, but that was quickly ruled out when I realized the spacing still wasn't correct.

Maybe they were going to have something custom made just for them? Kinda like early Hayes stuff?

All I know is if you want a disc mount on the back of these arm's you gotta make an adaptor or weld something on.

With a little luck i'll be all-rolling by this weekend, provided the LBS comes through. [smiley=worry.gif]

Glad to hear it's not too serious, Terry. Oh, hey, don't be to quick to dismiss physiotherapy. You never know who you'll meet at places like that.

You are lucky. Intra-articular fractures can be very bad or no different from other places. Depends on how bad it is. A displaced intra-articular fracture may never heal, while a small, non-displaced one may not cause any problems at all. (like yours hopefully).

I'm beginning to think I may be lucky too. The pain is getting better daily. My doc thought I had a greater tubercle fracture (humerus), but that just doesn't seem right. If I had to guess now, I'd say I strained my supraspinatus muscle (possibly a small tear). If there's any fracture, it's minimal and improving fast. I have full motion now (not limited by pain).

Ah, Philmont. Went there in '89. What a fantastic place. I love ultralight backpacking, except that with all the lightweight stuff I've collected over the years, rather than making my pack lighter, I just end up taking more. Backpacking has started to seem like a luxury vacation with all the "amenities" I can fit in my pack!

Unfortunately, I don't get much chance to go any more (my time will come - probably when my kids get old enough to go along). Also, mountain biking has ruined my fascination with backpacking somewhat. I can't hike anymore without thinking how much more fun the trail would be on my Proflex! Oh well...

Oh, and don't neglect physical therapy. You can probably just get some exercises to do on your own, but depending on how much you're favoring your shoulder, a "frozen" shoulder can be a real possibility. The shoulder is more prone to this than other joints because you can move your arm about 30 degrees without actually rotating that joint (by moving the entire shoulder blade).

Carbon_Angus · « **Reply #27 on:** August 16, 2005, 05:27:24 am »

Terry, do what your doc says to do. If you have a fracture of your scapula, then you will have a lot of pain moving that shoulder. Forget about trying to get full range now. Let it heal, but you will probably be in for some rehab, be patient. [smiley=beer.gif]

ps send any spare vicodin my way! (just kidding)

scratched skewer...broken scapula

One good thing is (Matno and I will attest) You will probably be able to ride your bike sooner than later.....just don't fall for a while, okay???

Frank..those holes on the swing arm are for a disk mount adapter. The bike was under k2 ownership in 97 and they deciced against having a disk option due to the idea of the bonding agent becoming heated during intense braking and causing the droipout to come loose...but the holes are for an adapter....it's differnt form a 4500/carbon frame though. They never researched it, just had the dropouts made with disc adapter holes. They did come up with an adapter at one time, but seemd to have problems with it.

Hey Carb,

Takin it easy I will!

Your expaination says it all. K2 thought there may be a problem with heat but it looks like they chose poorly. Hammerhead proved them wrong. Heck if there truly was a problem with heat they could have fabed a cool carbon adapter. Hows about titanium. Oh well.

My mom in law has dibs on the Vicadin. (She can have that doodie).

Terry

Frankd3000 · « **Reply #29 on:** August 17, 2005, 01:36:17 pm »

Ahhh, I see now. They were going to sell an add-on adaptor. Wish they did - it would save me some fab work right now.

I am enlightened. [smiley=nod.gif]
