Sram:

Were 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. A new optimized layup drops further grams from our hollow carbon arms, and to stay on top of current fit trends weve added our first carbon 160mm crankarm length option. And our X-Range gearing keeps your cadence change during a front shift to the minimum, maximizing your ability to put power down.
