SRAM Rival eTap AXS HRD FM Power Meter 2x12-speed 35-48 Groupset - black/172.5 mm 35-48, 10-30

SRAM Rival eTap AXS HRD FM Power Meter 2x12-speed 35-48 Groupset

Item number: 82458

The Rival eTap AXS HRD FM Power Meter Groupset for a 2x12-speed drivetrain with a gradation of 35-48

The SRAM Rival eTap AXS complete groupset includes a power meter crankset with 35 and 48 teeth and provides a cost-effective solution for an electronic 2x12-speed drivetrain including power measurement on your road bike. The proven QUARQ technology analyses power, cadence and torque for you on the left side. The cassette allows for even gear graduations, and the variant up to 36 teeth opens up a wide range for you. The hydraulic disc brakes are mounted via flat mount. For optimal grip, the shift/brake levers are rubberised and the grips have a textured surface. Its eTap shifting logic is intuitive: you shift up on one side, down on the other. Pressing both levers at the same time operates the front derailleur. AXS allows you to spare wiring the rear and front derailleur, and the matching app allows you to personalise your electronic groupset on-the-go and adjust it as needed.
