Key Features

2×12 eTap AXS Wireless Electronic Shifting

Rival E1 front and rear derailleurs use SRAM’s eTap AXS wireless protocol for quiet, consistent, cable-free shifting. The 12-speed drivetrain provides tight gear steps and a wide range suitable for racing, endurance riding, and climbing.

Integrated Power Meter (DUB Crankset)

The Rival E1 crankset includes SRAM’s spindle-based power meter, measuring left-side power with high accuracy. It’s lightweight, weatherproof, and compatible with the AXS app for calibration and firmware updates.

Hydraulic Disc Brakes (Flat Mount)

Rival E1 HRD shift/brake levers pair with flat-mount hydraulic calipers for stable, predictable braking on long descents and in variable weather. Reach adjustment allows ergonomic setup for a wide range of hand sizes.

12-Speed XG-1250 Cassette

The included XG-1250 cassette offers smooth progression and fast shifting under load. Common ratios include 10-30T and 10-36T to support steep climbing and fast rolling terrain.

Flattop 12-Speed Chain

SRAM’s Rival E1 Flattop chain provides increased strength, low noise, and long wear life. It uses PowerLock for tool-free installation.

AXS Connectivity

Pair the groupset with the SRAM AXS mobile app to customise shifting behaviour, check battery levels, and update firmware. Two AXS batteries and a charger are included.
