Shimano XTR Trail M9020 Double ChainsetThe Shimano XTR Trail M9020 Double Chainset is a high-quality and reliable double chainset that's perfect for long off-road adventures and trail riding.This stunning model integrates your bottom bracket and chainset into one strong, robust and lightweight workhorse. Furthermore, it is compatible with all new XTR chainrings thanks to its integrated design which makes installation and adjusting easier than ever before. Its precision bottom bracket bearings are spaced further apart and are therefore more stable and longer lasting.What's most impressive, is its super-lightweight HollowTech II cold forged Dualumin crank arms deliver an excellent strength to weight ratio, so you can conquer every technical trail without any unnecessary weight holding you back. If your existing cranks are old or worn-out, this is an ideal choice of a replacement for getting back to fast and precise acceleration and shifting out on the trails.Please Note: Bottom Bracket is not includedFeatures: Material: Arm: Super-lightweight HollowTech II cold forged Duralumin; Outer Chainring: HollowGlide Titanium/Aluminium composite Speed: 2x11-Speed Easy to use splined bottom bracket spindle Compatibility: All new XTR chainrings; 11 speed HG-X-chains only 34/24 or 36/26 with a 48.8mm chain line and a 168mm Q-factor ideally suited for all-mountain use in conjunction with 11-40T cassette Please note that the bottom bracket is not suppliedTechnologies:HollowTech: Hollow forged crank arms. A lightweight crankset not only reduces the bike’s weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the HollowTech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweightHollowGlide: Hollow technology on the outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength.
