The SRAM RED AXS power meter breaks with tradition — and breaks through to new levels of performance. We reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. We also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. Designed with Quarq DZero power measurement integrated into the crankset. Welcome to the pinnacle of the power meter.

FEATURES

• X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
• Power meter is fully integrated into the chainring set for lighter weight
• Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
• Measures right and left leg power balance
• Improved front shifting performance for crisp and accurate front shifts
• Unique chainring shape results in a lighter weight, stiffer, more durable crankset
• Integrated chainring design significantly reduces weight
• DUB bottom bracket adds durability, simplicity and broad compatibility

TECHNOLOGY

AXS

AXS is SRAM’s new wireless bike component integration system that connects electronic bicycle components and software. The SRAM AXS App allows riders to see battery status, change component behavior personalize controls, get maintenance reminders, and update firmware. 

Exogram

The new Hollow Carbon Construction starts in the crank arm and extends into the cranks' spider. It maximizes the stiffness to weight ratio. 

Yaw

The front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new Red crankset and chainrings, delivers an unmatched performance advantage in front shifting. 

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what is possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM has completely re-imagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you are always in the right gear. 

DUB

DUB technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.
