SRAM RED AXS™ Power Meter

The SRAM RED AXS™ power meter breaks with tradition — and breaks through to new levels of performance. We reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. We also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. Designed with Quarq DZero power measurement integrated into the crankset. Welcome to the pinnacle of the power meter.

Features

• X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
• Power meter is fully integrated into the chainring set for lighter weight
• Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
• Measures right and left leg power balance
• Improved front shifting performance for crisp and accurate front shifts
• Unique chainring shape results in a lighter weight, stiffer, more durable crankset
• Integrated chainring design significantly reduces weight
• DUB™ bottom bracket adds durability, simplicity and broad compatibility
