The SRAM RED AXS power meter throws tradition overboard and breaks through to a new level of performance. By reducing the chainring size and increasing the gear range of the cassette, we have redefined and redesigned the gear ratio on racing bikes from scratch. At the same time, we have retained the 13-tooth gear shift between the chainrings in order to guarantee precise gear changes in every setup. The result is a gear ratio that is better usable in all configurations and a fundamentally better circuit. Our power meter is also equipped with DZero, Quarq's premium power measurement system integrated into the crankset. Welcome to the Olympus of performance measurement.
