Seen on our cross-country and enduro bikes, theyre light enough for all-day trail use and durable enough for us to throw down on big park days. The newest XT offering is equipped with a cinch chainring to minimize creaking and weight while working with the latest and greatest Shimano 12-speed drivetrain systems.

  • Durable every-day and any-bike crank arm
  • Cinch chainrings install easily and are hassle-free
  • Upgraded crank arms for the 12sp Shimano family
