I recently swapped my old 25t 10 spd cassette with a new 28t 10 spd cassette and chain. Now the chain makes quite a bit of noise in the top half of the cassette only in the big ring which it didn’t before. It’s not rubbing the FD and I’m 99% sure the indexing is correct. I’ve tried adjusting the b screw but it doesn’t seem to make a difference. Any ideas?

Thanks in advance
