SRAM Red E1 2x12 Speed DUB Crankset, 46/33T 172.5mm

SRAM Red E1 2x12 Speed DUB Crankset

• One-piece 2x chainring results in a lighter weight, stiffer, more durable crankset.

• 29g 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 175mm lengths.

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. A new optimized layup 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. And our X-Range gearing keeps your cadence change during a front shift to the minimum, maximizing your ability to put power down.
