Product Overview

The SRAM Rival AXS E1 2×12-Speed Groupset delivers fully wireless electronic shifting and confident hydraulic disc braking in a performance-focused, accessible package. Built on SRAM’s AXS ecosystem and eTap shift logic, the E1 generation introduces refined ergonomics, reduced braking effort, and improved hood comfort—bringing flagship-level usability to the Rival tier.

Designed around X-Range gearing, the system pairs closely spaced chainrings with a wide-range 10T-start cassette to maintain smooth cadence progression while offering substantial overall range. With simple wireless setup, app-based customization, and proven hydraulic braking performance, Rival AXS E1 is equally suited to endurance road bikes, modern race builds, and all-road applications.
