The SRAM RED 1 AXS crankset features exceptional 1x drivetrain design. It provides the simplicity and tighter gearing range that is well-suited for road racing and riding in flatter terrain where a wide range would go unused. The crankset is designed specifically for electronic shifting and can be upgraded to a power meter.
