Pushing you towards a podium-topping finish, this stunning model uses a light carbon crank arm construction for immense durability. Vision has also gone the extra distance with this version by equipping it with CNC-machined 7075 aluminium chainrings, so you can enjoy their powerful torque performance without any excess weight. This is a perfect solution for soaring your way past your competitors for a victorious finish.
Ready for training, this power meter chainset features two high-quality carbon crankarms, which deliver exceptional stiffness and 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 and precision as you beat your personal performance goals. With a powermeter that delivers measurement readings that are accurate within +/-1.5% and aren't affected by climate conditions, you'll enjoy reliable results and performance data whatever the weather conditions. Coming complete with AXS wireless connectivity as well as renowned technologies such as DUB, DZERO, X-range and Exogram, this is a great choice of upgrade for reaching new goals and 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 and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalise controls, get maintenance reminders, and update firmware. Bluetooth and ANT+ Compatible With SRAM's power measurement technology that uses Bluetooth Low Energy (BLE) and ANT+ connectivity, you’ll have the technology to get real results. Your riding and 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 and 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% and 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 and 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 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: AXS is SRAM’s bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalise 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. Exogram: SRAM's Hollow Carbon Construction starts in the crank arm and extends into the crank’s spider, maximizing the stiffness to weight ratio.
