SRAM RED AXS Power Meter Crankset 170mm 48/35t – Road Bike Power Meter

The SRAM RED AXS Power Meter redefines precision and versatility for road cyclists seeking cutting-edge performance tools tailored to their demands. Engineered specifically for electronic drivetrains, this power meter integrates seamlessly into your setup while delivering unmatched shifting efficiency through its revolutionary X-Range gearing system. With a consistent 13-tooth gap between chainring pairs across all configurations—including its versatile 48/35T double chainring combo—riders enjoy smoother transitions between gears whether conquering steep climbs or accelerating on flat terrain during races or endurance rides.

At its core lies Quarq’s DZero technology embedded directly into the aluminum chainrings mounted on carbon crank arms, ensuring accurate power measurements (+/-1.5%) unaffected by rain or extreme temperatures during outdoor training sessions or competitive events. This integration eliminates bulky external sensors found on other meters like Stages or Garmin Edge models while maintaining precise left/right leg balance tracking—a critical feature for optimizing pedaling form and preventing muscle imbalances among professional athletes and serious enthusiasts alike.

The design prioritizes both weight reduction and stiffness: carbon crank arms paired with direct-mount aluminum rings create an ultra-light yet robust platform ideal for high-intensity efforts such as criterium races or century rides. The SRAM DUB bottom bracket interface (sold separately) enhances durability without compromising simplicity when upgrading drivetrains on road bikes equipped with standard 9/16″ pedal spindles and fork spacing up to 415mm chainstays paired with 130mm hubs or road disc setups at 135/142mm.

Key Advantages Over Competitors:
