The XTR HollowTech II M9020 Trail Crank Set from Shimano are the ideal cranks for riders who want additional strength for the abuse of aggressive trails and enduro racing. These 11-Speed cranks are cold forged and designed for bikes using a 53.4 chain line for 148mm O.L.D. 27.5+ bikes. The cranks are made from Duralumin with an anodized finish, and use the integrated bottom bracket system that fits together to make your crank set into a strong, rigid and lightweight unit. By not being sold with a chainring, this allows you to choose the perfect set up for your bike. Available in Black only.
