Shimano Xtr M9120 Boost Crank

This Shimano XTR M9100 MTB Crankset 12-speed is a real upgrade for your mountain bike. The crankset is very light, thanks to the extra thin chainrings. These are needed because a 12 speed cassette is connected to it, this means there is less room for a thick chain and the chainrings are automatically made thinner. These chainrings are manufactured with great precision, so that optimum shifting performance is achieved. The crankset is provided with a Hollowtech II axis, which is very strong and does not deform. As a result, all your supplied power will end up on the wheels. Another big advantage of this crankset is that it is possible to mount a second chainring. All in all, the complete set only weighs 511 grams.Specifications: - High-quality Crankset for MTB´s- The chainring is very thin due to the narrow 12 speed chain- Axis type: 24mm (Hollowtech II)- The strong axis does not deform for efficient power transmission- The chainring ensures optimum shifting performance- Q-Factor: 168 mm- A second chainring can be mounted- Light weight- Spiderless assembly- O.L.D: 148mm.- Arm length: 175 mm- Chain line: 51.8 mm- Weight: 511 grams
