A lightweight with top performance. The XTR FC-M9100 Hollowtech II crankset has not only received a facelift, but is also even lighter than its predecessor. The crank arms are still made of hollow forged aluminium, yet do without a spider. Shimano uses a Direct Mount standard with BB lock ring to mount the chainrings on the 12-speed crankset. The inner chainring is simply installed with the bolts of the outer chainring. Thanks to 28T and 38T chainrings, this crankset forms the perfect drivetrain system together with Shimano's XTR CS-M9100 12-speed 10-45 cassette for long distances and steep climbs. The optimized 4-arm chainrings securely hold the chain in rough terrain thanks to dynamic chain engagement (DCE+) - for a direct pedal feel.
