When you put down the power, the Shimano XTR M9100 12-Speed Chainset will transfer the result like no other crankset on the market. A new direct mount big ring design saves weight and increases stiffness, with the big ring mounted 28 tooth smaller ring also closer and easier to shift to. The M9100 Chainset features a narrower XC 162mm Q-Factor which will work best with cyclocross and XC hardtail frames - if you have something beefier, chose the 9120 crankset. The 28-38 tooth design will combine with the 11-45 cassette to offer a massive gear range (well over 500%) and see you climb pretty much anything in your path. Thanks to the special tooth profile, even with up and down shifts, chain drops should be a thing of the past. For the ultimate in race ready performance, the new Shimano XTR M9100 12-Speed Chainset is simply unstoppable.

  • Combine wide range and close gear steps
