Ready for training, this power meter chainset features two high-quality carbon crankarms, which deliver exceptional stiffness & strength without adding any unnecessary weight to your road bike. SRAM has also equipped this model with a single X-SYNC narrow/wide aluminium chainring for maximum chain control & precision as you beat your personal performance goals. With a powermeter that delivers measurement readings that are accurate within +/-1.5% & aren't affected by climate conditions, you'll enjoy reliable results & performance data whatever the weather conditions. Coming complete with AXS wireless connectivity as well as renowned technologies such as DUB, DZERO, X-range & Exogram, this is a great choice of upgrade for reaching new goals & taking your training sessions up a notch. Road Bike Power Meter with AXS Wireless Technology AXS is SRAM’s bike component integration system that connects electronic bicycle components & software. The SRAM AXS app allows riders to see battery status, change component behavior, personalise controls, get maintenance reminders, & update firmware. Bluetooth & ANT+ Compatible With SRAM's power measurement technology that uses Bluetooth Low Energy (BLE) & ANT+ connectivity, you’ll have the technology to get real results. Your riding & training efforts deserve power measurement that reaches the highest standards of accuracy to help you reach personal records. Because without accurate data, you can’t know if you are making the progress you’re aiming for. Another highlight is the chainring can be easily changed without requiring recalibration of the power meter. Non-aero chainrings can also be installed with a single tool, making gearing changes a breeze. Technologies:
- Single-ring drivetrain simplifies functionality.
- 48 & 50T variants have fully integrated power into a direct mount aero chainring.
- 36-46t variants have a spider-based power.
- Chainrings can be easily changed without requiring recalibration of the power meter.
- Power readings are accurate within +/-1.5% & aren't affected by climate conditions during a ride.
- 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 & simplicity.
- Non-aero chainrings can be installed with a single tool, making gearing changes a breeze. X-SYNC: SRAM X-SYNC 1x chainrings provide the highest level of performance & durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp & 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 & rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. AXS: AXS is SRAM’s bike component integration system that connects electronic bicycle components & software. The SRAM AXS app allows riders to see battery status, change component behavior, personalise controls, get maintenance reminders, & update firmware. DUB: The relationship between bottom bracket spindle & bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking & made everything simpler—better integrating the relationship between chainring, crank, spindle & 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 & innovative projects to detect subatomic particles moving at the speed of light. X-Range: Road bikes are faster & more capable than ever before, & 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 & smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear. Exogram: SRAM's Hollow Carbon Construction starts in the crank arm & extends into the crank’s spider, maximizing the stiffness to weight ratio.
