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.
