SRAM Rival XPLR eTap AXS 1x Flat Mount DUB Electronic Groupset

With components designed specifically for the challenges of gravel riding; the SRAM Rival XPLR eTap AXS 1x Flat Mount DUB Electronic Groupset is the ideal addition to any bike build themed around adventures or races over testing trails and tracks. 

SRAM’s AXS format wirelessly connects the levers to the rear derailleur, offering super-easy installation and faultless gear shifts. With a simple touch of the lever buttons, the rear mech, with its redesigned b-knuckle, smoothly and accurately glides over the wide-ranging 10-44T, 12-speed cassette. With such a wide range of gears available, any severity of terrain becomes more manageable, and the single chainring setup of the chainset promotes simplicity and chain security over rough surfaces.

All of the rider’s power is transferred to the drivetrain thanks to the light, stiff and strong aluminium crank arms and their partnering, oversized DUB spindle. Stopping duties are taken care of admirably by the hydraulic disc brakes that grant confidence and control in all weather.

Between rides, the gear system can be connected to the AXS smartphone app, offering the opportunity to manage and customise gear changing behaviour and monitor battery levels across all of the components.
