Tux07 Posted April 13, 2010 Report Share Posted April 13, 2010 Hi, I have recently brought a 05 Onza T-Rex to get back into trials an I have come to a dead end with the cranks. I have tried an external B/B set but a 22tooth chain ring does not line up (not unless I want I section missing from my frame lol) I believe this is due to the chainstay yokes being wider than most bikes I've seen, has anyone come acoss this before an could you recommend cranks to fit. many thanks Rich Quote Link to comment Share on other sites More sharing options...
Revolver Posted April 13, 2010 Report Share Posted April 13, 2010 Probably some ordinary isis cranks, and a wide BB, 128mm Quote Link to comment Share on other sites More sharing options...

Tux07 Posted April 13, 2010 Author Report Share Posted April 13, 2010 hi, i'll have to see what depth i can get away with on the shimano arms as at a guess it'll be around 12mm off each lug. cheers for the tip Quote Link to comment Share on other sites More sharing options...
Tux07 Posted April 14, 2010 Author Report Share Posted April 14, 2010 (edited) i'm goin to leave my shimano cranks as a friend may be buying them, i have spotted neon cranks on ebay that take screw on free-wheels am i right in guess that a fixed cog for the rear will screw on with a bash N.B. when i last rode trials the bikes still looked like mtbs so pretty much any part would fit Edited April 14, 2010 by Tux07 Quote Link to comment Share on other sites More sharing options...
