More than just a chainset, SRAM's new Red DUB Chainset combines the new slick shifting X-Range one-piece chainrings with a Quarq Dzero Power meter to provide highly accurate power measurement and some of the slickest shifting available.X-Range gearing provides more range and smoother gear progression, so you're always in the right gearUnique 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 separatelyCarbon-tuned crank arms are super light and incredibly stiffDUB bottom bracket system adds durability, simplicity and broad compatibility (DUB BB sold separately)The highlight of the new Red DUB AXS Power Meter Chainset is the X-Range chainrings with a built in Quarq Dzero Power meter. Using 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 cassette 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 XG-1290 cassette means the Red DUB chainset 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. The integrated Quarq Dzero is cleverly packaged as part of the chainrings, 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%, given a highly accurate reading to help you train and ride harder. The chainrings also feature closer ratio spacing than traditional double or compact chainsets, so you have a smoother progression between ratios, keeping your cadence more consistent and requiring less rear shifts to compensate, further improving the smoothness of your cadence and speed. The smaller gap also means shifting faster and crisper.The Red DUB AXS Power Meter chainset uses SRAM's carbon-tuned crank arms that are both incredibly light and extremely stiff. The use of the DUB bottom bracket system improves durability, simplicity and compatibility over the older GXP and BB30 designs; no more wondering what crank/BB system will fit your bike, DUB works with most frames and bottom bracket shells on the market. The cranks use a unique, modular direct mount chainring interface that syncs perfectly with the new one-piece X-Range chainrings. The modular design further improves versatility; you can fit the regular non-power meter Red double chainrings as well as the single 1X or Aero chainring. Lighter, stiffer, more durable and with a better gear range than ever before, the SRAM Red DUB Chainset perfectly complements the Red eTap AXS groupset to create the ultimate, versatile road bike drivetrain.
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.
