Bought new rear wheel and new cassette what spacer do I need for behind the cassette? 1mm? 2mm? 3mm?

Hub is Pro2 evo, cassette is 11-36 10 speed.

Should I use plastic or aluminium spacer?

Does the cassette not fit fine without a spacer ?

Ah…. That should have been in the original post too I reckon… Does it need one? I remember reading somewhere that it the cassette needs a spacer to stop binding?

Haven’t fitted it yet.

I never fitted one and it worked fine, pro2 evo+XT 11-36 combo..

OK, thanks, I’ll just bung it on and see what happens 🙂

Spacer?

some road cassette/freehub combo’s need spacers but I’ve not heard of it on mtb’s.

There are loads of posts on the Internet.. Mainly relating to mavic hubs it seems.
