you know i think that the Torker DX came out before Qu-AX. and if not it is not based on Qu-AX is it based on the bike’s that Redline bikes (the company that own’s torker). hence why its 8 spline, if you look at redline bikes… same thing alot of their cranks are inter-changeable with torker unicycles.

It’s 10 spline. 
if it is 10 spline, does that mean that quax cranks fit on it? it wouldnt help much, because they arent much shorter, but it is just a question
