SRAM Red E1 Crankset

SRAM is not one 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 SRAM added their first carbon 160mm crankarm length option. And the X-Range gearing keeps your cadence change during a front shift to the minimum, maximizing your ability to put power down. Features One-piece 2x chainring results in a lighter weight, stiffer, more durable crankset 29 g lighter than the previous generation X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Crisp and accurate front shifts Ultra-light hollow carbon fiber crankarms DUB bottom bracket adds durability and simplicity 50/37T, 48/35T and 46/33T chainring combos available Can be upgraded to a power meter Available in 160, 165, 167.5, 170, 172.5, and 175 mm lengths
