RED 1x XPLR Wide Crank Arm Assembly
Lighter. Stiffer. RED.
We're not ones to rest on our laurels. So when we found ways to make our lightest and stiffest crankarms even lighter, we went for it. A new process drops further grams from our hollow carbon arms, and to stay on top of current fit trends we've added our first carbon 160mm crankarm length option.

Hollow Carbon Construction
