Are you absolutely sure it's not a 7-speed (not patronising at all) ?
8 and 9 speed cassettes are the same size so I can't see why it would make a difference?
anyway if i buy a new wheel it will be fine
Even though those are some of the WORST pictures known to man, it looks like the end of the cassette body - where the largest sproket sits - is a little chewed up, and maybe not sitting totally flush.
Try filing any burrs / inperfections off with a SMOOTH file, and see if it fits.
Yeah, but try and get hold of a file, borrow one, anything. It will take about 15 mins. And I'm pretty sure you'd like a spare wheel / wheelset, for the sake of 15 mins work. Regardless or not whether you wanted to upgrade.
Besides, if you fix it up, you could always sell them... More £££ for the bike fund... :twisted:
