I’m in need of a new cassette (and chain and chainring). Currently running a 30T chainring with XT 11-46T and the jump from 37T to 46T has always been a bit big. I’d be happy with 11-42T range with a 30T chainring up front, I don’t use the bike on the road and don’t run out of top end gears. Sticking with shimano freehub as have a couple sets of wheels, which rules out SRAM GX. So what’s the best value/performance/durability balance?
SRAM NX PG1130 11-42T £63
Shimano XT M8000 11-42T £66
Sunrace MX8 11-42T £57
I could consider the 11-46T MX8 for £60 as it has a better spread of ratios than the XT 11-46, maybe with a 32T oval. Though it’s possible the bigger jumps are noticeable around the 15-18-21 gears. And I think 11-42T with as 30T chainring will be fine, possibly with better shifting without the such a big low gear.
