TheXTR M9100 12 Speed Cassette has been created with an increased transmission ratio, is 30%stiffer than previous models and keeps a lower weight to maximise efficiency when making those vital shifts. Equipped with a 10-45 or 10-51 teeth system, cadence jumps when moving between gears are kept low to maintain high-speeds and steady rhythm as you blast through your run.
Featuring Hyperglide+ technology, the cassette benefits from small shifting ramps leading the chain to the next sprocket when going up through the gears and on the way back down, stopping the chain from dismounting. This ensures consistent gear-stepping at all times with no impact to your cadence.
A fantastic set of sprockets for the thrill-seeking trail and downhill rider, theXTR M9100 12 Speed Cassette is more than equipped for the rowdiest of rides.
