Sram Red Axs Dm Dub

Crankset Red E1 DUB 160mm Direct Mount 5037T (BB not included)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.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 lengthsSPECIFICATIONS- Speeds:12- BB Compatibility: All SRAM Road DUB BBs- Chainring Size: 46/33T, 48/35T, 50/37T- Crank arm length: 160mm, 165mm, 167.5mm, 170mm, 172.5mm, 175mm- Chainline : 45.0mm- BB Spindle Interface: DUB- Chainring material: Aluminum- Guard: No Guard- Bolt Circle Diameter (BCD): Direct Mount (DM)- Crank arm material: Carbon- Color (Crank arm): Natural carbon- Power meter: No- BB Spindle Interface DUB
