Couldn't load pickup availability
The SRAM Rival AXS E1 2×12 road groupset with power meter brings together wireless electronic shifting, hydraulic disc braking and integrated power measurement for road racing, sportives and everyday riding. A choice of double chainrings and cassette ranges lets you tailor the gearing to your local roads and bigger riding plans.
The best upgrades earn their place every time you ride. The Bike Lab can help you work out how Rival fits into your existing bike or a fresh build, with straightforward advice and personal support from an independent bicycle business.
Built for the road
Wireless AXS shifting provides precise gear changes without gear cables, with customisable settings through the SRAM AXS app. The 2×12 drivetrain offers closely spaced ratios for settling into a comfortable cadence, with lower gears available for longer or steeper climbs.
Rival flat-mount hydraulic disc brakes provide controlled braking on descents and in changing conditions. Adjustable lever reach helps you find a comfortable position at the controls.
Integrated power measurement
The spindle-based power meter measures left-leg power to calculate total watts, giving you useful data for training, pacing and tracking progress. It sits inside the DUB spindle and offers over 400 hours of battery life from a user-replaceable AAA lithium battery.
