spangler Posted August 20, 2005 Report Share Posted August 20, 2005 I was wondering i anyone knows where i can get hold of a long axled square tapered bb For all these new trials frames with short backends. The bt6 for instance needs 127mm axle length I used to have a 120something raceface signiture dh square taper that was sweet and never broke but that went with my last frame. You cant get lengths that long anymore Wiggle are selling a 145mm version but i dont know if that will be strong enough? I'm running 20t middleburn protrials 's help!

Tomm Posted August 20, 2005 Report Share Posted August 20, 2005 You can get UN53s in 127.5mm, CRC have 68x127.5s HERE if it's any use to you. I think you can just bosh a 68 into a 73mm frame anyway... Quote Link to comment Share on other sites More sharing options...
spangler Posted August 20, 2005 Author Report Share Posted August 20, 2005 i was hoping i wouldnt have to get a shimano one as ive had lots of the axles break on me but if there the only ones that will fit i guess i got no choice. any others?

tipsy Jock Posted August 20, 2005 Report Share Posted August 20, 2005 i have a 127.5 x 68 square taper in my pitbull, means running a 20t ring though. Its hard to find a 73mm version but if you can then whack a spacer in the driveside (provided frame is 68mm) then you have an extra 5 mm of width (well on one side anyway).

spangler Posted August 20, 2005 Author Report Share Posted August 20, 2005 i havent actually bought a new frame yet but i didnt want to have to buy another set of cranks. ive just found that the kot ms2 frames need 68mm bb and 122.5 for 22t i run 20t so do you think i could get away with running a shorter length Quote Link to comment Share on other sites More sharing options...

But I would go with a 122.5 to be safe. Quote Link to comment Share on other sites More sharing options...
