You can likely upgrade your current 8, 9, 10, or 11-speed equipped bicycle, provided you have the following:
XDR driver body: Replacement XDR driver bodies are available from most wheel manufacturers to retrofit 11-speed road rear hubs. If you currently have an 8, 9, or 10-speed drivetrain, upgrading your wheelset or rear hub to one that incorporates compatibility with an XDR driver body will allow you to install an eTap AXS groupset to your bike. To verify if your hub is XDR driver compatible, contact your hub manufacturer to verify if they produce a compatible XDR driver for your specific hub. The SRAM version XDR drivers are compatible with SRAM hubs only.
Flat mount calipers: Rival eTap AXS is offered with flat mount disc brake calipers only. If your frame is not equipped for flat mount disc brakes, Rival eTap AXS is not compatible.
Post mount calipers: Rival eTap AXS and Force eTap AXS are not available in a post mount disc brake caliper option. There is a SRAM RED post mount disc caliper option and hose kit that is available separately. Additionally, Level disc brake calipers are compatible with SRAM RED, Force, and Rival eTap AXS hydraulic brake levers.
Mechanical rim brake calipers: Rival eTap AXS is not available in a mechanical rim brake option. Both SRAM RED and Force eTap AXS offer a mechanical rim brake option.
