SRAM Red AXS E1 Shifter and Disc Brake

The SRAM Red AXS E1 shifters are designed for the latest Red AXS ecosystem. While they are part of the 12-speed AXS family, you should verify specific firmware and component compatibility with your existing derailleur generation to ensure seamless pairing.

Yes, the system features extensive customization. You can independently adjust both the reach and the contact point, allowing you to dial in the lever position and engagement feel to perfectly match your hand size and braking preference.

This hydraulic system is designed to run on DOT 5.1 brake fluid. It is important to use the manufacturer-recommended fluid to maintain the integrity of the seals and ensure consistent braking performance.

The integrated auxiliary buttons are programmable via the SRAM AXS app. You can configure them to control your cycling computer, such as toggling through screens or triggering laps, without needing to take your hands off the hoods.

Absolutely. The lever pivot point and ergonomics are optimized for leverage, allowing you to generate significant stopping power with just one finger. This design helps reduce hand fatigue and provides more secure control when navigating technical terrain.

The E1 generation has undergone a significant weight reduction compared to its predecessors. By refining the materials and internal architecture, SRAM has created a lighter overall system that improves bike handling without sacrificing durability.
