The absolute pinnacle of road drivetrains: unbeatable lightness, extraordinary stiffness, and flawless shifting.
The SRAM Red AXS DUB E1 crankset represents the state of the art for cyclists who demand maximum efficiency and the smoothest possible power transfer. Thanks to a new optimized hollow carbon layup, this crankset further reduces weight while increasing torsional stiffness. Designed for 2x12 speed electronic drivetrains, the combination with the 165 mm crank arm and X-Range gearing technology guarantees a consistently smooth cadence and instantaneous front shifts, making it the definitive component for racing and high-performance road bikes.
CRANKSET SRAM RED AXS DUB E1 12V 50/37T (165MM) MAIN FEATURES:
- Crank Arms and Structure: Ultra-lightweight hollow carbon arms with optimized layup, with a 165 mm length designed to promote a more agile, biomechanically efficient, and responsive pedaling stroke.
- Drivetrain and Gearing: X-Range chainring technology with one-piece 50-37T chainrings to reduce cadence jumps and maximize power transfer.
- DUB Bottom Bracket: Standard DUB compatibility for exceptional stiffness, lightness, and increased durability of the bearings and the entire system.
- AXS Electronic Integration: Specifically designed to work in perfect synergy with the wireless front derailleurs and controls of the SRAM AXS 12-speed group.
- Front Shifting: Refined tooth profile and Road-Yaw shifting for fast, precise, and quiet chain transitions even under maximum load.
- Aerodynamic Design: Premium finish and lines of the SRAM Red E1 range for an elegant, modern, and high-performance look.
