I have a Xero Xr -210 wheels and a 105 5600 10spd cassette.
When I went to remove the cassette it had gouged several grooves into the freehub body. So bad it took two chain whips and some swearing to remove them.
The cassette has a sprocket carrier for the big 3 sprockets but the rest are individual and here is where the trouble begins. Each one only has about half the number of splines that the freehub has therefore twice the drive on each one. This makes it bite into the freehub all the more.
I've looked at Shimano's website and the nearest was a 13-25 but no one has any.
Sram's website was even less help.
I reckon I need a cassette that has a more sprockets mounted onto a spider. Does anyone know where I can get one. Preferably a 12-25.
