We’re not ones to rest on our laurels. So when we found ways to make our lightest and stiffest crank even lighter, we went for it. New construction technique drops further grams from our hollow carbon arms, and to stay on top of current fit trends we’ve added our first carbon 160 mm crankarm length option. Paired with an aerodynamic 1x chainring, this crank is ready to help you smash PRs.
