Sram Rival AXS XPLR D1
Wireless 1x Gravel Precision. Unmatched Chain Security.
The engineering highlight of the Sram Rival XPLR eTap AXS Derailleur is its gravel-specific XPLR 1x architecture combined with an eTap spring clutch. Engineered explicitly to operate across 10-44T and 10-36T cassettes, the derailleur body maintains constant chain tension across every gear cog. Operating on Sram’s proven eTap wireless logic, gear changes are instantaneous, completely wire-free, and customizable through the Sram AXS mobile application.

The Alegro Perspective: Rival XPLR derailleur is the absolute sweet spot for building or upgrading a dedicated 1x gravel rig. Sram's 10-44T XPLR cassette range gives you that coveted 1:1 (or easier) climbing gear for steep, loaded bikepacking routes, without forcing you into massive MTB-style gear jumps on flat gravel sectors. Setup is a breeze. Once you set your limit screws and B-gap, it stays dead quiet and perfectly indexed over miles of rough dirt.
