Hi
Does anyone know if the internal parts of hub of the wh9000 c24 dura ace fit in the rs81 c24 hub shell?
I heard the 9100 model parts do fit, but want to make sure the 9000 ones fit as well. Thanks

I am aware the inside parts are different. What I wanted to know is if those internal parts do fit inside the hub shell of the other model. Thanks though

You just need to replace the bearings on the RS81 with better grade aftermarket ones. And you are done.

Typial RS81 bearings are about Grade 100 steel balls, get something in the Grade 20 or better range. They are relatively inexpensive, but just stay away from the ceramics and stick with steel ones.
