In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS™ power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains.The SRAM RED AXS™ power meter breaks with tradition — and breaks through to new levels of performance. The power meters are designed with Quarq’s premier DZero™ power measurement technology fully integrated into the crankset. Welcome to the pinnacle of the power meter.Key Features:X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gearIntegrated power measurementPower meter is fully integrated into the chainring set for lighter weightPower readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ridePower balance measures left and right legs separatelyImproved front shifting performance for crisp and accurate front shiftsUnique chainring shape results in a lighter weight, stiffer, more durable cranksetIntegrated chainring design significantly reduces weightDZERO™ - 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. With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke, and software advances, DZero represents the state of the art in power meter technology.AXS™ - AXS is SRAM’s new electronic integration platform 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.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 imitations.CARBON TUNED™ - Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.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 re-imagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings – enabled by AXS™ App. With X-Range, you’re always in the right gear.Specifications:Speeds: 12Crank arm length: 170mm, 172.5mm, 175mm, 177.5mmBB Compatibility: All SRAM Road DUB BBsChainring Size: 46/33, 48/35, 50/37Bolt Circle Diameter (BCD): Direct Mount (DM)Chainline: 45.0mmBB Spindle Interface: DUBChainring material: AluminumGuard: No GuardCrank arm material: CarbonColor (Crank arm): Natural carbonPower Meter Type: ANT+ and BLE

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. Our power meters are also designed with Quarq’s premier DZero™ power measurement technology fully integrated into the crankset. Welcome to the pinnacle of the power meter.

Quarq DZERO Road Power Meter ChainsetFeaturing two high-quality carbon crankarms, this powermeter offers exceptional stiffness, strength and low weight performance on your road bike. Quarq has also equipped this model with two SRAM X-Glide aluminium chainrings for additional durability and precision as you clock up the miles. Designed for compatibility with most 10 speed and 11 speed drivetrains, this powermeter is fitted with a Quarq DZERO DUB spider power meter that delivers accuracy within 1.5%, measuring both legs. Another highlight is it comes complete with many of Quarq's renowned technologies such as MagicZero, AxCad and OmniCal as well as 10K Temperature Compensation and an IPX7 waterproof rating for accuracy and consistency in any weather conditions. DZERO Road Powermeter with X-Glide ChainringsImagine being able to shift smoothly at any time, no matter what. We're talking full-power shifts. Up, down, whatever the road demands. The benefit of X-Glide chainrings is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you'll never again compromise your speed and power in unpredictable road conditions. Quarq precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in the right gear, right now.Bluetooth and ANT+ CompatibleYour 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. With Quarq's premier DZero power measurement technology that uses Bluetooth and ANT+ connectivity, you'll have the technology to get real results.Reach new goals and explore new roads with a power meter that delivers on accuracy, durability, and reliability.

The SRAM Quarq AXS Aero Power Meter Kit makes use SRAM's new X-Range gearing technology, offering smoother shifting and a wider gear range. The rings are combined with an integrated Quarq Dzero power meter that provides accurate power measurement. Unique one-piece chainring design features a built in Quarq Dzero Power MeterPower meter is accurate within +/- 1.5% and balances power between left and right leg separatelyX-Range gearing provides more range and smoother gear progression, so you're always in the right gear8-bolt direct mount interface - only compatible with SRAM Red D1 and Force D1 cranksUsing a unique one-piece design that bolts straight to the crank arms, the X-Range rings work in conjunction with the X-Range XG-1290 and XG-1270 cassettes to provide a wider gear range and smoother progression between gears, meaning you'll always be in the right gear. The unique 10t start of the cassettes means you can use smaller chainrings than normal while retaining a similar gear for top speed. The smaller chainrings also mean you'll have a lower bottom gear for punishing climbs. Unlike other SRAM chainrings, the Quarq AXS Power Meter uses a unique 8-bolt direct mount interface that is only compatible with SRAM Red D1 and Force D1 cranks.The integrated Quarq Dzero is cleverly packaged as part of the chainring, reducing weight and making it possible to switch the power meter between compatible Red chainsets. The power meter has a power balance feature, that measures power from left and right legs separately and is accurate within +/- 1.5%, giving a highly accurate reading to help you train and ride harder.
