This is the SRAM Red DUB 1x Aero E1 Crankset.

When we found ways to make our lightest and stiffest crank even lighter, we went for it.

A new process 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.

Paired with an aerodynamic 1x chainring, this crank is ready to help you smash PRs.

Features:

• Single-ring drivetrain simplifies functionality and reduces weight
• Direct mount aero chainrings for better aerodynamics
• X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control
