Well it's 48 spline and it was stuck so my friend at the bike shop took it off for free and I got it painted and.. I tried putting it together and it didn't come together past a certain point so I checked it out and theirs a bump in the splines on the crank arm.. So is this regular or is it fucked? Also I have 1664 cranks so could I just buy like a crank arm off dans and put it on or do I have to get new cranks?
