Description

In order to design a better product, sometimes you have to let tradition go. The SRAM Force AXS power meter is a prime example. By moving the range from the front of the drivetrain to the back and creating a consistent 13-tooth gap across all variants of chainring duos, we were able to improve shifting performance and give riders the gearing they truly want and need. Designed specifically for electronic shifting and featuring Quarq’s premier DZero power measurement technology, the SRAM Force AXS power meter is a huge step forward in power meter design.

Technology

AXS

AXS is SRAM’s new 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.

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.

DZero

Quarq’s next-generation DZero power meter platform is named for the D0 Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.

X-Range

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

Reviews

Cycling Component of the year

The shifting is great, and it provides such usable gear ratios for the type of riding it is designed for, whether that's on or off-road.

Quiet & comfortable

"Shifting in any condition is easy, whether rattling on a gravel descent or commuting in snow, with lobster-mitt gloves on."

Gear of the Year

"...it’s just so consistently good; battery life is impressive, shifting accurate and consistent, and the gearing spread is just what I’ve been looking for..."

Superb overall performance

“…the smaller gap of just 13 teeth up front feels good. The front derailleur works as quiet and reliable as no other front derailleur. Same for the new Flat-Top-Chain. Wear was surprisingly little.”
