has anyone put a rc51 rear wheel on a f4i, and if so what does it take to do it

 

i'll trade you the rc51 rim for a f4i rim,

 

but the cush drives are different

 

I believe the axle is smaller, I know its the same size as the 954 rear. Probably have to get the 954 chain adjustments to put on there. The f4i sprocket and rear rotor and caliper are the same as the rc51 though. I just put the rc51 wheels and front/rear end on my f4i.
