Gt tech shop cranks

Re:

Have a few on a couple different bikes and a couple pair hanging on the wall. Have one version that I don't have on any bikes yet. I believe that there were three versions. All CNC GT designs made by Profile.

This is probably my favorite version....note the "All Terra" logo mountains machined into the arms. Guessing this was an early crank maybe even a prototype because it never appeared in any of GT's catalogs or ads that I can recall.

Note also that the version pictured in the 1992-95 catalogs is basically the crank arm shape that Shimano copied for their M950/M952 XTR arm shape.

OOps almost forgot this one....thanks to an old friend named Hans for sending me an old 23T chainwheel he had lying around I was able to get this 155mm version back where it belonged on a Team Trials. I also have a 155mm version on a 24" wheeled Zaskar so that it's anatomically sized for the rider.

If anyone out there has a Syncros or Kore trials stem they don;t need I'd like to get one back on the bike in this picture.

...Or there's only so many ways to make a tapered box with a kink in it, given that otherwise the design of the M95x crank has no similarity whatsoever.
