While our new X-Range gearing technology has brought much of the simplicity of 1x drivetrain to a 2x setup, there are still disciplines where a single-ring drivetrain shines. The SRAM Force 1 AXS power meter offers improved aerodynamics for triathlon and time trial bikes, thanks to a direct mount aero chainring option with integrated power. It also provides the simplicity that cyclocross racers crave. And the tighter gearing range is perfect for road racing and riding in flatter terrain, where a wide range would go unused.
- Single-ring drivetrain simplifies functionality
- 48t variant has fully integrated power and a direct mount aero chainring
- 36-46t variants have spider-based power
- Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
- Power balance measures left and right legs separately
- SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control
- Laser-etched chainring finish is more durable
- DUB bottom bracket adds durability and simplicity
- Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.
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.
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.
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.
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.
