Sram Red AXS E1

Wireless Perfection.

The RED AXS E1 represents a total optimization of the AXS ecosystem. By shedding 16g compared to the previous version and utilizing larger X-SYNC pulleys, Sram has created a drivetrain that isn't just lighter, but also significantly more mechanically efficient. It is the ultimate "one-derailleur" solution, capable of handling both 1X and 2X configurations across a massive variety of cassette ranges, from a tight 10-28T up to a climbing-friendly 10-36T.

Why the RED AXS E1 is the Performance Benchmark:

• Orbit™ Fluid Damper: Unlike traditional mechanical clutches, the Orbit fluid damper provides silent, sophisticated chain management. It keeps the chain perfectly tensioned over bumps while remaining completely friction-free during shifts, ensuring the fastest gear changes possible.

• Larger X-SYNC Pulleys: Increased pulley size reduces the angle of chain deflection, lowering internal friction and saving valuable watts. An essential gain for racers looking for every marginal advantage.

• AXS Wireless Integration: Lightning-fast, wireless shifting that is incredibly easy to set up. Use the AXS app to customize your shifting patterns, check battery levels, and update firmware directly from your smartphone.

• Refined Aesthetics: Features a sleek, minimalist design that complements the most advanced carbon frames. The high-polish and carbon finishes make it a stunning centerpiece for any flagship build.

• Universal Capability: One derailleur cage size works for everything. It’s ready for the road, the local crit, or your favorite all-road loops, supporting any cassette from 10-28T to 10-36T.

• AXS Ecosystem Compatibility: Works seamlessly with all existing AXS batteries and controllers, allowing for easy integration into your current high-end setup.

The Alegro Perspective: The "E1" update isn't just a facelift; it’s a notice to the industry that wireless road shifting has reached its peak. The reduction in weight and the increased efficiency of the larger pulleys make a tangible difference in how the bike feels under load. We recommend this for the rider who wants the best of the best. The cleanest setup, the lightest weight, and the most reliable wireless performance on the market.
