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. Features: X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Integrated power measurement Power meter is fully integrated into the chainring set for lighter weight 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 Improved front shifting performance for crisp and accurate front shifts Unique chainring shape results in a lighter weight, stiffer, more durable crankset Integrated chainring design significantly reduces weight DUB™ bottom bracket adds durability, simplicity and broad compatibility Specifications: Speeds: 12 Crank arm length: 170mm, 172.5mm, 175mm, 177.5mm BB Compatibility: All SRAM Road DUB BBs Chainring Size: 46/33, 48/35, 50/37 Bolt Circle Diameter (BCD): Direct Mount (DM) Chainline: 45.0mm BB Spindle Interface: DUB Chainring material: Aluminum Guard: No Guard Crank arm material: Carbon Color (Crank arm): Natural carbon Power Meter Type: ANT+ and BLE

The SRAM Quarq AXS Aero Power Meter Kit makes use of a unique direct mount aerodynamic X-SYNC chainring with an integrated Quarq Dzero power meter that improves aerodynamic performance, while providing impeccable chain retention and 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 separatelySingle chainring design simplifies functionality and reduces weightX-SYNC chainrings provides impeccable chain retention8-bolt direct mount interface - only compatible with SRAM Red D1 and Force D1 cranksThe X-Sync chainring features a special laser-etched finish that is more durable, improving the usable life of the chainring; this isn't just for race day only. The unique X-Sync narrow-wide too profile is not only supremely efficient and durable, but it also provides impeccable chain retention. 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.

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.
