Shimano Deore XT M770 Cassette
Best durable upgrade for mountain bikers running 9-speed drivetrains.
This is the gold standard for keeping a 9-speed drivetrain relevant in a world obsessed with more gears. You sacrifice the tight spacing of modern 12-speed setups, but you gain the legendary, bombproof reliability that Deore XT is famous for.
