Problem with fitting cassette to new wheels :(

Hi,

I've brought a pair of Reynolds Shadow wheels to replace my Mavic Aksiums. Seem like great strong basic wheels.

Except one problem. My 10 speed Sram pg1070 cassette seems to big. As in it fits on the freewheel body fine but the smallest cog dosn't fit, seems free wheel body is too short.


See this pic, might make it clearer -

This is without the smallest (12T) cog fitted, as you can see there is no real room for it. It will fit on, and the lockring will hold it in place, but as you can see it's only the very edge of the cog that's going to connect with the freewheel body and I wouldn't like to ride it like that.

I don't know, but it's like the freewheel is only designed for a 7, 8 or 9 speed cassettes, not 10, didn't know there was even a difference.

But my question is what can I do about it?

(I've tried 3 different cassettes, all the same problem).

Please help, I'm desperate.

  • im no expert, but i think it is ok, because when you tighten the nut down your 12 tooth will have more to sit on. I fitted a 11 speed chorus yesterday and had similar problem.

    on the mavic wheels there's a spacer between hub and cassette, c. 3mm for a 10-speed cassette

    many other wheels do not need a spacer

    so if you've moved the spacer to the new wheel, that might explain it

  • WHS ^^^^ is the thin sliver spacer stuck to the back of the cassette??

    I know what you mean, but no, the spacer has already been taken off.

    Do you think it's safe to do as stevesavage71 suggests and use and the cassette will compress down when the lock ring is tightened?
  • Yep, just tighten the lockring and all the sprockets and spacers will be locked together and the smallest sprocket will be on the splines just fine.
