Shimano Crankarm Defore M6000/M8100

The crank arms are crafted with Hollowtech II technology, balancing stiffness, strength, and weight for superior power transfer. Hollowtech uses cold-forging technology to create a light and hollow crank arm that doesn't compromise on stiffness, enabling you to charge hard into rowdy trail sections without worries of your crankset flexing under pressure, meanwhile the light weight keeps you from getting bogged down with extra grams when you're pushing for big mile days.

• Shimano's 12-speed crank arms for on-trail performance
