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 Garmin Vector 3 is the latest version of Garmin’s popular power meter pedals. As a pedal-based power meter with sensors housed inside the pedals, the Garmin Vector 3’s offer highly reliable data, which is accurate to +/-1%. In this dual-sided iteration, the Garmin Vector 3 gives you an exact, independent reading of each leg's power output. It even measures where power is being applied to the pedal, so you can ensure optimal cleat set up. One of the huge benefits of running a pedal-based power meter is the ease of set up. Without needing to exchange cranks, swap out wheels or chainrings, even the most basic mechanic can swap these pedals between bikes in minutes. With a lower stack height, these pedals also offer much more cornering clearance than the previous model, so you can sprint out of hairpins with confidence. While the stainless-steel spindle ensures the Vector 3’s last a long time, due to the composite pedal body, the Vector 3’s weigh just 316 grams per pair. Powered by coin-cell batteries which are easy to replace, the Vector 3’s offer 120 hours of riding. Being a Garmin product, the Vector pedals are best combined with Edge computers and Forerunner watches. However, as a fully ANT+ and Bluetooth capable power meter, you don’t have to worry about integrating the Vector 3 power meter with other ANT+ and Bluetooth compatible devices. Battery type: LR44/SR44 (x4) Battery life: 120 hours Weight: 316 g Max. rider weight: 105 kg Accuracy: +/- 1.0% Cleat type: Keo Q-factor: 53 or 55 Stack height: 11.5 mm Cornering clearance: 31.7 Static friction: 1.9 Field calibration Adjustable release tension Garmin Connect™ Measurement location: spindle Communicaiton: ANT+® and Bluetooth® Installs like a regular pedal Included: Vector 3, Look Keo style cleat hardware, Documentation A Garmin HRM dual heart rate monitor measures your heart rate during training, so you can understand your body better, train more effectively and achieve greater results.
