![]() Weight: 778 grams (GXP 172.5mm 53x39 BB not included)īuilt off the proven Next R crank arm shape and spindle insert, the Next SL stands to be lighter, with major improvements in durability and carbon consistency. With Quarq's free Qalvin app – available for Windows, Mac, iOS and Android – you can set the zero offset, check battery voltage, run diagnostics, and perform firmware updates for freeĪrm Material: Carbon arms, Machined alloy spider Built to Last – IPX7 waterproof rating, 2-year warranty, free firmware updates, and acclaimed international support Manual and automatic zeroing make it truly set and forget The replaceable CR2032 battery never leaves you without power Easy to use (and reuse) – LED indicator and visible ANT+ ID Breakthrough Materials – Exogram hollow carbon fiber crank arms – the lightest, strongest crank arms SRAM makes – minimize weight and maximize speed AxCad – A multi-axis accelerometer switches the power meter on and measures cadence, simplifying installation and operation 10K – programmed with over 10,000 data points to eliminate temperature effects on power measurement Uses a hidden bolt to mount the chainrings – compatible SRAM chainrings ensure the derailment pin lines up behind the crank arm Number 1 at the Ironman World Championship for the last three years Proven by pro teams and athletes throughout the world – Cobbled Classics, Giro d’Italia, Tour de France, Vuelta a España, World Championships No compromises on materials, shifting, wheels, or pedal choice Works for every discipline: Road, triathlon, time trial, and cyclo-cross A direct force power meter that measures total power output from both legs with +/-1.5% accuracy The chainrings are replaceable should your bike, discipline, or ability change. This power meter works for every discipline: Road, triathlon, time trial, and cyclo-cross. It is the perfect place to measure power. The sole job of the crankset is to convert the effort from both legs to forward motion. ![]() The crankset is the heart of your bicycle and where you’ll find the SRAM RED Quarq power meter. Bolt Circle Diameter (BCD): Direct Mount (DM) BB Compatibility: All SRAM Road DUB BBs, GXP/PF GXP 68mm Unique chainring design results in a lighter weight, stiffer, more durable crankset The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick-every time. This leads to smoother and faster shifting up front and more useful gearing for today's riders. The SRAM RED crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. DUB bottom bracket adds durability, simplicity and broad compatibility Integrated chainring design significantly reduces weight Unique chainring shape results in a lighter weight, stiffer, more durable crankset Improved front shifting performance for crisp and accurate front shifts Power meter is fully integrated into the chainring set for lighter weight X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear Welcome to the pinnacle of the power meter. These power meters are also designed with Quarq's premier DZero power measurement technology fully integrated into the crankset. This results in more useful gearing and better shifting across all configurations. They also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. SRAM reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. ![]() The SRAM RED AXS power meter breaks with tradition - and breaks through to new levels of performance. BB Compatibility: All SRAM Road DUB BBs Non-aero chainrings can be installed with a single tool, making gearing changes a breeze DUB bottom bracket adds durability and simplicity Laser-etched chainring finish is more durable SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control Power balance measures left and right legs separately Power readings are accurate within +/-1.5% and aren't affected by climate conditions during a ride Chainrings can be easily changed without requiring recalibration of the power meter 36-46T variants have spider-based power 48T and 50T variants have fully integrated power into a direct mount aero chainring Single-ring drivetrain simplifies functionality 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. ![]() ![]() Championing simplicity, strength and durability, the SRAM RED 1 AXS power meter meets the demands of triathletes, time trialists and cyclocross racers. In certain disciplines, the single-ring drivetrain reigns supreme. ![]()
