you cant.

i had the same problem.
for some reason stock cranks are just a pain in the ass like that.
the one i had was an 8 spline pinch bolt onto the crank spindle.
the pinch bolt part (where the arm connects) of the crank spindle was 19mm, but tapered into 20mm because thats the size of the unsealed bb bearings.

what size is your new bb?
if you can get a spindle that fits the new bb and your old cranks and is the right spline and stuff, then its possible.
but those tapered spindles are a pain in the ass.


you're honestly better off just spending the cash and getting a new crankset to go with that new frame. :)

cheers.

yea that the reason i havwe a new frame in my room for almost 4 mounths.... i almost have enough money for new cranks.

redline makes a 20mm spindle with 19mm splines but get some new cranks. The stock ones weight a lot and are weak.
