SRAM took a unique path with their gravel-oriented component selection. By further unleashing the freedom and power of eTap AXS electronic shifting and their experience with wide ranging, durable Eagle mountain drivetrains, the R&D team simply added wide crank and 1x chainring options in the Red, Force, and Rival groups, created a new cassette optimized for gravel gearing, then crafted an AXS Rear Derailleur for each group level that could handle the extra range and physical requirements from the fastest to most punishing gravel experiences available. The XPLR (read: explorer) line then just adds new overall capability without creating a dedicated group, so at all three price points, a similar set-up is available- plus the components are cross compatible. Unique and innovative- with a new way forward for component and system integration, as seen here through Rival XPLR eTap AXS Rear Derailleur.

The Rival XPLR eTap AXS rear derailleur is a dedicated 1x12-specific unit designed for use with the XPLR 10-44T cassette (and is compatible with the Force 10-36 as well). It makes for an uncluttered drivetrain that takes on pavement and singletrack with equal aplomb. Wireless and proven eTap shift logic, AXS connectivity and advanced chain management mean this derailleur does exactly what you want when you need it. The construction and material quality is all at the Force-level, which has been the best overall performance/value combination in the SRAM road line-up since it's release.
