Bring fully wireless, app-tunable electronic shifting and confident hydraulic disc braking to your road bike with SRAM's flagship RED eTap AXS upgrade kit. Crisp one-finger braking, near-instant gear changes and a clean, cable-free cockpit make every ride feel sharper, without replacing your existing cranks or wheels.
- Fully wireless 2x12-speed eTap AXS electronic shifting
- HRD hydraulic disc brakes with flat mount callipers and 160mm CenterLock rotors
- Personalise shift logic and check battery life from the SRAM AXS smartphone app
- Interchangeable, rechargeable batteries shared across front and rear derailleurs
- Orbit fluid damper keeps the chain quiet and secure over rough roads
- Rear derailleur handles cassettes up to 33T maximum
Effortless wireless shifting
Each derailleur carries its own removable, rechargeable battery and talks to the levers over SRAM's encrypted AXS wireless network, so there are no shift cables or wires to route. Tap a paddle to shift the rear, both paddles to shift the front, and use the SRAM AXS app to remap the controls or fine-tune shifting exactly how you like it.
Confident hydraulic braking
The HRD shift-brake levers arrive paired with pre-filled flat mount callipers and steel-backed CenterLock rotors for reliable, easily modulated stopping power. The lever shape and hydraulic design make controlled one-finger braking comfortable from the hoods or the drops.
Quiet, secure drivetrain
SRAM's Orbit fluid damper manages chain movement to reduce bounce and noise on rough surfaces, helping keep the chain seated and the drivetrain running smoothly.
Compatibility and fit
This is an aftermarket upgrade kit for 2x12-speed SRAM eTap AXS road setups using flat mount disc brakes and CenterLock rotors. The rear derailleur is the 33T-maximum version, suited to 10-26, 10-28 and 10-33 SRAM 12-speed cassettes. A SRAM 12-speed cassette, chain and a compatible crankset are required to complete the build and are not included in this kit. If you are unsure whether your frame, wheels or existing components are compatible, contact the Tune Cycles team before ordering.
