Description

SRAM are not ones to rest on their laurels. So when they found ways to make their lightest and stiffest crank even lighter, they went for it. A new optimized layup drops further grams from the hollow carbon arms, and to stay on top of current fit trends they’ve added their first carbon 160mm crankarm length option. And X-Range gearing keeps your cadence change during a front shift to the minimum, maximizing your ability to put power down.
