SRAM RED XPLR AXS E1 – Precision Power Measurement for Elite Gravel Performance

Take your gravel performance to the next level with the SRAM RED XPLR AXS E1 DUB Wide Power Meter Crankset. Combining accurate dual-sided power measurement, ultra-lightweight carbon crankarms and a premium 42-tooth chainring, this high-performance crankset is engineered for riders who demand precision, efficiency and reliability.

Designed specifically for SRAM RED XPLR AXS gravel drivetrains, the crankset integrates power measurement into the chainring spider, delivering valuable training and racing data without compromising drivetrain performance.

The advanced power meter measures total power output and left/right leg balance, helping riders analyse pedalling efficiency, optimise training intensity and make informed decisions during demanding races.

Featuring SRAM's latest hollow carbon crankarm construction, the RED XPLR E1 is engineered to provide exceptional stiffness and reduced weight. The redesigned crankarms are 29 grams lighter than the previous generation, delivering a responsive and efficient pedalling experience.

The DUB Wide spindle configuration provides the chainline required for compatible gravel frames and wide-stance drivetrain setups, while the 42T chainring offers a versatile balance between high-speed efficiency and climbing capability.

Available in three crank lengths – 170 mm, 172.5 mm and 175 mm – this premium crankset allows riders to choose the ideal fit for their bike and pedalling preferences.
