Wireless shifting means one less cable to route, maintain, and replace. The SRAM Red AXS E1 Brake-Shift Lever with Caliper takes this further by pairing their top-tier electronic shifting with a flat-mount hydraulic disc brake in a single integrated package. You get the lever, the caliper, the hose, and the fluid already bled and ready to install.

The shift paddles use SRAM's AXS wireless protocol to communicate with Red or Force AXS derailleurs. No wires between the lever and the drivetrain means the cockpit stays clean and you eliminate potential failure points from cable stretch or housing contamination. The paddles themselves are programmable through the AXS app, so you can swap which paddle shifts up versus down, or set both paddles on one lever to control the same derailleur if that matches how your brain works. Battery life runs around two years of typical riding per lever, and swapping a CR2032 coin cell takes about thirty seconds.

The hydraulic brake side uses DOT fluid rather than mineral oil. The lever reach adjusts without tools, and contact point adjustment lets you dial in where the bite engages during the lever stroke. The included caliper mounts to flat-mount frames and forks directly. This particular kit ships with a 160mm rotor for the front wheel, though the caliper works with 140mm or 180mm rotors depending on your braking demands and frame compatibility.... Read More
