The new SRAM Red AXS E1 wireless groupset represents an additional leap forward in cycling technology, blending effortless performance with cutting-edge innovation. Every component has been meticulously refined from its predecessor to offer a seamless and lightweight riding experience. The new groupset features intuitive, fully wireless shifting and highly adjustable braking that can be controlled with just one finger, catering to riders of all hand sizes. Additionally, the SRAM Red AXS E1 features enhanced gearing options to meet the diverse needs of cyclists, from road racers to gravel enthusiasts unlike ever before. Whilst, the integrated power meter, known for its accuracy and consistency, provides reliable data for performance optimization.

The choice of SRAM's top professionals, their lightest, stiffest, and most accurate integrated power meter and chainring combo just got lighter with a new carbon crankarm construction. The SRAM power meter is accurate to +/-1.5% and isn’t affected by temperature changes, and the consistent 13-tooth gap on the rings ensures fast and reliable shifting. SRAM's integrated rings are also incredibly long-lasting. Plus they're offering more crankarm lengths than ever before to ensure this crank works for you. *Power meter is fully integrated into the chainring for lighter weight and greater accuracy *Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride *Measures right and left leg power balance *One-piece 2x chainring results in a lighter weight, stiffer, more durable crankset 29g lighter than the previous generation X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
The SRAM RED AXS XG-1290 cassette is an integral part of the RED AXS drivetrain system. With a 10-tooth small cog and X-Range gearing, it progresses fluidly and quickly through a wide range of gears. Carefully chosen tooth jumps keep the rider in the right gear when you’re out of the saddle on steep climbs and making fine changes to hold a wheel while approaching a sprint. These cassettes are designed specifically for wireless electronic shifting, and the one-piece design offers exceptional weight savings. The XG-1290 cassette is designed to operate with XDR driver bodies. *More gradual gear progression between cogs (at least five one-tooth jumps) while still offering a wider range *One-piece machined steel X-Dome design offers strength with weight savings *10-tooth start helps provide a wider gearing range Designed to work with an XDR driver body
SRAM eTap Battery is the power source for the eTap system. The same power unit is interchangeable between front and rear derailleurs. - Up to 1000 kilometers of riding per charge - Weight: 24g - Finish: Black - Compatibility: SRAM RED eTap
Effortless performance. Effortless perfection. SRAM has refined every part of RED to create effortless one-finger braking, smooth front shifting, fully wireless connectivity, and expanded gearing choices to fit every rider. They packed in every feature they could, like new shift points and more brake adjustability, while still shaving grams off every component to bring you the lightest electronic groupset ever. Riding isn’t effortless. RED is. Groupset includes components needed for a 2x wireless setup in a single package - hydraulic brake/shift eTap lever pair, front and rear flat mount disc calipers, 160mm Paceline X disc brake rotors, front and rear wireless derailleurs, batteries, charger and cord, Quick Start Guide, and Hammerhead Karoo GPS bike computer *RED eTap AXS™ HRD Brake/Shift System provides simple and intuitive eTap shift logic and is AXS enabled for easy personalization *Shift/brake lever Bonus Button provides ANT+ device control or auxiliary shift option *RED eTap AXS enabled front derailleur uses Yaw technology with electronic trim to ensure the fastest possible shift while eliminating chain rub in all combinations, with the easiest setup around, thanks to a brilliant new tool *RED eTap AXS enabled rear derailleur covers cassette ranges from 10-28t up to 10-36t and features larger pulleys to decrease chain articulation and increase efficiency, and an Orbit fluid damper to keep everything in place over the rough stuff *Calipers are stiffer and lighter than the previous version and offer phenomenal pad clearance for rub-free operation
