TPI On Profile Racing Cranks
« on: August 26, 2011, 03:35 PM »
Hi all - anyone know the TPI for Profile Racing cranks - got an axle that the threads are a little bit damaged (fixable though without drilling larger) and need to get a tap to do the job - ta in advance  :daumenhoch:

I might actually build a bike this year instead of just hoarding parts :)

i thought the profile axle was a 3/8" 26tpi. i remember snapping a bolt years ago and using a piece of a wheel axle with a nut on it to replace it. suppose it could have been a 24 tpi axle tho. they were the same thread as the old g sport hub bolts too.
