I installed 11-40 Shimano Deore XT M8000 11-speed Cassette. It works good enough for me. It does not
shift as nice as the 11-34 that came with the bike. I prefer the 11-40 for the mnt bike trails that are over 15%. I can't imagine how the 11-42 would fit. The 11-40 is pretty tight.

The biggest draw back is when I put my road wheel set on ( 11-30 ) I have to make adjustments to the b screw. Before I had to do nothing switching between my gravel wheel set when it was 11-34 and my road wheel set of 11-30.
