I've got photos of 2 bikes at the London 1996 bike show with Hope disk brakes on a set of aluminium vectors.  That's what caused all the original messages on the pre-idriders forum about the (in)famous Hope D-mount for the vectors and also the reason why myself and mike always tell people not to add disk brakes to vector aluminium forks - they basically fold up and crease the left leg - I've was sent a report from Girvins testing (they had an elaborate rig for the vector testing) and also destroyed one myself (whilst I was riding it).    Anyway, as I recall, during the bike show Girvin rang up Hope and asked them to remove and stop selling them.

Its also why I never sold Mikes carbon fibre crosslink kits because there was too much risk associated with a sloppy build by a customer or a carbon fibre fault leading to an injury... 

There is nothing like having forks collapse under you to remind you of responsibilities for engineering.

I remember reading somewhere that a disc brake-specific Crosslink or Girvin leg might have been available. Anyone ever hear or see wuch a thing? I believe I may have read it in my Crosslink owners manual.

Just wondering...I'm plenty happy with my Magura HS33's and don't really see the need for discs.

not that I have heard of - the only ones I have seen are adaptations made by people on this forum (some very good ones at that - see OldProflexers' for example).... but note Callum's words of warning above.

I sent Jalon (Desperado Cycles) an email - asked him to join us here and say hello.

OP

not sure how he'll take his creation as being described as 'whacky' - i like it.
don't think the stress on a aluminum leg for the bikes intended purpose would be much of a concern.

don't think we've ever seen mike's carbon crosslink kit - please post a picture

unfortunately, that Oz was stolen from outside his house by a prospective buyer...  I'll look through some old photos this weekend to find a picture.   I'm not saying that CF forks can't have disk brakes - I'm just saying it is not an easy job and there is a lot of scope for doing it wrong. so take care

Might want to recheck with Hammer on that - according to his post on the bike that was stolen in the last year or so - that one had a Marzocchi fork -
Was under the impression somehow the mike would not be riding a crosslink -

Thanks for the heads up guys...

The bike I had stolen was fitted with grimeca hydraulic discs, hammerhead adapter at the rear, marzocchi forks, shimano wheelset... quite distinctive. I have not been able to access ebay here from work, I'll have a look at the link Bill sent me in the mail...
In a way I hope it is not my stolen bike, because I don't want to go through all of that....   and chances are that the person selling it actually bought it in good faith, so it would be like stealing it from them too...

It was stolen in Sweden by some low life... probably is on some hill-billy farm somewhere in sweden, or sold for 30 bucks to buy drugs...

Goes around and comes around...

Take it easy,

Hammer.


Don't think any of us ever go to see a picture of one that he put together -
Very interested to see what it looks like compared to the ones I was making back in '01 and '02.

OK, it took a while, but I REALLY like that! Looks like it has a drum brake in frontand something similar in the rear.

drum brakes are pretty interesting because they are shielded from the elements - however, they really overheat quickly.  The ones I have seen (indeed, only yesterday on a friends commuter bike) have radial cooling fins!

The nice thing is that do not require lugs on the frame to operate - I'm sure I have seen them on a combined rohloff internal gear hub as well.  will investigate.

Well, look at that! The Brown Fox and Blue Fox drawing some attention!

The Brown Fox was revamped to serve my purpose of riding out in my back yard which consists of around 140,000 acres of forest land and 2200 miles of off road trails – right out my back and that is what the DNR tells me is in my county alone in north east Wisconsin. There are areas the water never has a chance to dissipate due to the clay in spots and I decided that using a Sachs internal Super 7 with a drum brake on the rear and one on the front would do. I have over 30,000 miles on that hub- not a miss-print- and  I tried the Shimano 8 this year and it lasted 3 runs of 10 miles before I lost the top 4 gears. There is not a lot of braking to be had around here and these serve their purpose very nicely. Using a garden hose after the run on the mud and throw a little chain lube on and go back and do it again.

By the way, do you like that Ti rail saddle? Not the most comfortable saddle on the market but it has that banana seat “S” logo on it and the color matched!

Thanks for your interest folks!

Hi Jalon,

Yes, I like the color match all around. That is a seatpost that I have never seen before also.

Got to say, that is one very good looking and unique full susser. ;D

Do you plan on building any others?

A good portion of my work these days goes into doing Schwinn cantilever customs for people all over the world. The suspension thing I think could be a bit pricy due to the fact that I would have design and make the rear triangle (this has been done http://www.desperadocycles.com/Neils_Rides/Phoenix_Phinal.jpg (http://www.desperadocycles.com/Neils_Rides/Phoenix_Phinal.jpg)). The obstacle is that the shock is no longer available. It uses a clamping design rather than a bolt. If anyone knows of a source I’d like to know.

Risse makes a replacement rear air shock to work on the AMP Research rear triangles...

Just FYI...

Thank you for the information. I actually have one of these on my “King Of Diamonds” and it works great. Just after I posted, I thought that I should check the manufacture… Looks like you beat me to it! I will see what I can do here…

You could also use a swinglink to free the shock from the strut, like the new Proflex carbon.

Well, I didnt mean any disrespect by calling the bike wacky, it actually looks well made, but, lets just say its definatly not really my cup of tea, and while I've seen a few cool schwinn style frames built up as mountain bikes klunkers included I generally love old pre-war 1939 and older (some newer too) type bikes with that style frame.

Truth of the matter is folks; I was frame building with Columbus Metax Stainless at the time and True Temper Platinum steels. I am the only frame builder in the world (so I am told) to successfully silver fillet braze bicycle frames. This should be enough to draw attention to the media, but it did not. So I put this “Wacky” Schwinn together to market my work. BANG! Mountain Bike and Mountain Bike Action (Fiction to us) posted photos in the early 90’s of my Schwinn full suspension flicks. That is the story! The fact is, they are great to ride, and they draw attention anywhere thy go.

A rose called by any other name....

I might add, that a bicycle is different to everyone. Beauty is in the eye of the beholder and think of what you wish; I am “In Love” with this bike….
