Hobnobs Posted March 15, 2005 Report Share Posted March 15, 2005 Shimano UN53 122.5 as 127.5 might rub. 15 quid i think from bikedock. Might be even cheaper. Quote Link to comment Share on other sites More sharing options...
rocktrials Posted March 15, 2005 Author Report Share Posted March 15, 2005 68 or 73? Quote Link to comment Share on other sites More sharing options...
Hobnobs Posted March 15, 2005 Report Share Posted March 15, 2005 68mm shell fits mine fine :- Quote Link to comment Share on other sites More sharing options...
rocktrials Posted March 15, 2005 Author Report Share Posted March 15, 2005 cool, so which length? 122.5 or 127.5? Quote Link to comment Share on other sites More sharing options...
Mark W Posted March 15, 2005 Report Share Posted March 15, 2005 68x127.5 is adorning my T-Pro at present, although it's fractionally too long with an Eno freewheel on Muscleman cranks. I don't think that it would clear the BB shell with a 122.5 BB spindle though. Aaaaaaanyhoo, yeah, UN-53, 68x127.5, wiggle.co.uk or chainreactioncycles.com, job done. Mark. EDIT: The chain doesn't rub, btw. It's just that the chain-line is shocking, and is wearing the right side of my Eno out :- Quote Link to comment Share on other sites More sharing options...
Brisa Posted March 15, 2005 Report Share Posted March 15, 2005 I run a 68*122.5 un53 in my t-pro. Cranks are echo with an ACS claw and no bash ring. Plenty of freewheel/bb clearence. Quote Link to comment Share on other sites More sharing options...
Mark W Posted March 16, 2005 Report Share Posted March 16, 2005 ARe the remover tabs ground down though, or is it still all big 'n' sticky outy? Quote Link to comment Share on other sites More sharing options...
Brisa Posted March 16, 2005 Report Share Posted March 16, 2005 Big and stickyouttie... Quote Link to comment Share on other sites More sharing options...
Olly C Posted March 16, 2005 Report Share Posted March 16, 2005 Best bet as said is a UN53 127.5mm x 68mm £12 posted from Tartybikes Olly. Quote Link to comment Share on other sites More sharing options...

My chainline is a bent as the popes back with a 127.5 with muscleman cranks and acs freewheel Quote Link to comment Share on other sites More sharing options...

My chainline is a bent as the popes back with a 127.5 with muscleman cranks and acs freewheel ← I run an 18t fixed cog upfront with an echo bash there aswell, so my chainline is at less of an angle I'd guess. Its not perfect but its not doing to much harm from what I can see.. its pretty much the same as a mech aligning the chain. Olly. Quote Link to comment Share on other sites More sharing options...
