getting a new cassette this week which is slightly different to the one its replacing - 11-32 instead of 11-34.

I'm sure i'll be fine in changing the cassette over and installing a new chain but hadn't contemplated the possible need to shorten the chain in view of less teeth on the rear cassette. I'm kind of thinking (hoping) as its only 2 teeth i shouldn't need to?

The cassette will be an XT 770 and the chain KMC 9X SL

I've searched park tools and the how to's here but couldnt find an answer

cheers
