The SRAM Rival AXS E1 right lever with Flat Mount rear caliper embodies the democratization of high-tech wireless electronic technology for demanding cyclists. This fully cable and housing-free braking and shifting system combines hydraulic disc braking and AXS electronic transmission in a compact, lightweight, and ultra-high-performance package, specially designed for modern road and gravel riding.
Revolutionary braking: 80% less effort
SRAM has redesigned the lever ergonomics with a raised brake pivot point, reducing braking effort from the hoods by 80% compared to the previous generation. This major innovation enables powerful and modulated single-finger braking, whether from the hoods or the drops. The 2-piston aluminum caliper with steel-backed organic pads ensures consistent, quiet, and progressive braking power in all conditions. The Flat Mount 20 mm offset mounting guarantees optimal compatibility with modern road and gravel frames.
AXS wireless transmission: simplicity and reliability
- Intuitive eTap logic: right lever to shift up (harder), left lever to shift down (easier), both levers together for the front derailleur. Simple, intuitive, and error-free.
- AXS connectivity: quick setup, complete command customization, battery status monitoring, maintenance alerts, and firmware updates via the SRAM AXS app (iOS/Android).
- Universal compatibility: works with all AXS road rear derailleurs (10-30T, 10-33T, 10-36T) and XPLR (10-44T, 10-46T), in 2x12 or 1x13 speed configurations.
- No mechanical maintenance: no cables, housings, or indexing — zero adjustment after initial installation, simply pair the components and ride.
Redesigned ergonomics and comfort
- Carbon brake lever: optimal lightness and maximum stiffness for direct power transmission.
- Optimized hood shape: redesigned to fit a wide range of hand sizes, with textured surfaces for a firm and secure grip in all weather conditions.
- Extended Reach Adjust: improved lever reach adjustment for millimetric fitting according to hand morphology, eliminating any risk of finger pinching during hard braking.
- Textured shift paddles: immediate tactile access and perfect control, even with thick gloves or in the rain.
Simplified installation and maintenance
The pre-installed 1800 mm hydraulic hose with Stealth-a-majig mounting system allows discreet and aesthetic internal routing on all modern frames. Compatible with DOT 5.1 brake fluid, the system is ready to ride after bleeding and installation. Steel-backed organic pads (ref. SRAM 00.5318.024.001 and compatible) ensure quiet braking and progressive wear. Total weight of lever + caliper + hose assembly: approximately 746 g (without rotor), one of the best weight-to-performance ratios in the segment.
Available variants
