In-Depth Description

Every single detail pushed beyond the limit: Experience the definitive ride with the SRAM RED AXS E1.

The SRAM RED AXS E1 groupset is not just a minor update—it is a true ergonomic and structural revolution. SRAM engineers focused heavily on feedback from World Tour professionals to strip away every single non-essential gram while simultaneously redefining the pressure distribution points on your hands. The result is the lightest road electronic disc groupset ever produced, delivering lightning-fast shifting and unprecedented operation smoothness in any weather condition.

E1 Hood Ergonomics: One-Finger Braking

The new RED E1 shifter bodies feature a radically optimized silhouette. The top hood knob has been slimmed down and elongated to allow a more secure, ergonomic wrap when riding high on the hoods. However, the true breakthrough lies in the newly positioned brake lever pivot point: thanks to this geometric architecture, braking requires 80% less effort from the hoods compared to the previous generation. This allows you to stop the bike or modulate your speed using literally just one finger, completely eliminating muscle fatigue during long alpine descents.

High-Precision Integrated Quarq Power Meter

The SRAM RED E1 DUB hollow carbon crankset includes a factory-installed Quarq power meter integrated directly into the one-piece chainring design. This architecture offers dual-sided power measurement (separating left and right leg data) with a certified accuracy of +/- 1.5%. It is entirely unaffected by environmental temperature swings and does not require continuous manual recalibrations. X-Range gearing technology provides an optimal gear progression, keeping cadence steps small while maximizing energy efficiency.

Rear Shifting & Orbit Chain Management

The RED AXS E1 rear derailleur is a masterpiece of micromechanics and electronics. Equipped with the Orbit™ fluid damper chain management system, it keeps the drivetrain incredibly quiet and stable even over broken pavement, cobblestones, or fast light-gravel sectors. Compatible with cassettes up to 36 teeth, it features oversized jockey wheels with premium ceramic bearings as standard to minimize mechanical friction and save precious watts on every pedal stroke.

Mechanic's Advice:

The transition from the older RED series to the new E1 is impressive, especially once you get your hands on the hoods. The ergonomics are incredibly comfortable, and the increased clearance between the lever blade and the handlebar prevents you from pinching your fingers when braking hard while tucked deep in the drops. Keep in mind that the chain and cassette utilize the Flattop standard, which means they require compatible chain tools for installation. Before shipping, if requested in your order notes, we can pre-pair the electronic wireless components and verify firmware statuses so everything is ready to bolt on. Don't forget to let us know if your frame requires a threaded DUB bottom bracket (BSA) or a press-fit variant (such as BB86, BB30, PF30).
