SRAM Rival XPLR eTap AXS Upgrade Kit 12-speed | XG-1251 cassette | 10-44 teeth
With the XPLR upgrade kit you can convert your existing eTap AXS groupset for use on a gravel bike.
The new 1-way specific Rival XPLR rear derailleur has been specially developed for the needs of modern gravel riders. In combination with the matching XPLR cassette with 10-44 teeth, it gives you enough bandwidth to climb every climb. Tight gear steps on the smaller sprockets help you to keep your comfortable cadence in the high speed range. In-house technologies that have been tried and tested over many years ensure the necessary reliability in use under rough off-road conditions. The electronic radio eTap switching logic ensures intuitive switching processes and simple setup. You can personalize the switching behavior via the AXS APP. Enlarged pulleys with proven X-Sync Narrow-Wide tooth profile keep the chain securely in place, even with the toughest vibrations. In addition, a spring clutch is used to dampen vibrations. The necessary power is supplied by the proven SRAM eTap battery (not included), with which you can operate the rear derailleur over 1000 kilometers or around 60 hours of driving. An ANT + transmitter integrated in the rear derailleur enables communication between your bike computer and the rear derailleur. Among other things, you can have the charge status of the battery and the current gear displayed in your cockpit.
NOTE: The rear derailleur is only compatible with SRAM eTap AXS shift levers!
