8 to 9 speed

[derrick]

Can I replace an 8 speed cassette for a 9 speed cassette. On a set of mavic rims. Not into 7 8 or 9 speed. Don't know what fits what. Cheers.

I would look at Sheldon Browns page, cannot find it just now from the phone. Maybe https://www.sheldonbrown.com/k7.html

When I upgraded from 8 to 9 speed I put the cassette on the same freehub, but IIRC it depended on exactly which freehub you had. My hub was a Shimano C201, which had a freehub that subtly different from most though.

It's usually fine, although you may need a spacer. Depends on the age of the hub, and make.

So long as your shifter is upgraded to 9 speed!!

For clarity shifter means the control lever. The derailleur may well do 9-speed as well as 8- although again it depends on make. For a start, are we talking about Shimano or Campagnolo?
