Finding new terrain and fun gravel roads is easy with the SRAM Rival XPLR AXS Rear Derailleur hooked up to our rigs. This wireless derailleur utilizes tech from SRAM's wireless road and mountain bike groups to create a fun middle ground for every bike in-between. We use this derailleur on our thick tired gravel bikes and utilize the huge 44t capacity by outfitting a 1x drivetrain.
