hi just after some advice I’m upgrading my groupset from Claris to ultegra and my rear hub is an fh rs300 9 speed and I was wondering what replacement freehub I would need to change it to accept a 10/11 speed cassette?
Thanks in advance
Matt

That hub will take a up to a 10 but not an 11 spd. For 11 you'd need to re build wheel with an 11spd compatible freehub

8/9/10 are all the same. You might need a spacer behind the cassette if it won't lock down
I borrowed my cousin's bike on a holiday in Scotland and its cassette was rattling. He hadn't realised that it needed the spacer. His brother fitted one for him and it fixed the problem.

It isn't likely that I will be converting my 10-speed CX bike (or 9-speed MTB) to 11-speed, but if I ever decide to then that is very useful information - thanks.
