SRAM's X1 Crankset takes a less-is-more approach to mountain bike shifting. Paired with SRAM's 1x11-speed parts (sold separately), you get the gearing of a double or triple drivetrain, with greater simplicity, less noise, and reduced weight. There's less clutter on your bars without a front shifter and cable, and dropped chains and chainguides are a distant memory thanks to the ingenious X-Sync chainring teeth that hold your chain. On top of all that, the cranks themselves are seriously light thanks to the hollow-forged 6000-series aluminum arms and spider. Experience less with X1, because less is more.
