SRAM AXS Power Meter Spider D1

In certain disciplines, 1x drivetrains simply dominate.
With its unbeatable simplicity, stability, and robustness, the SRAM RED AXS™ retrofit power meter meets the exact requirements of triathletes, time trialists, and cyclocross racers.
The power meter is integrated into the direct-mount spider and, with its reduced gear range, is perfect for racing and flatter terrain. The RED AXS™ power meter is equipped with DZero™, Quarq's premium wireless power measurement system integrated into the crankset. Thanks to professional performance-based training, you'll be ready to climb the cycling Olympus.

Performance features:
1 or 2 chainring setup
The power meter is fully integrated into the chainring combination and weighs only 36g
Power measurement has an accuracy of +/-1.5% and is not affected by changing weather conditions during the ride
Power Balance measures separate values for the left and right legs.
Improved derailleur shifting performance for crisp and precise shifting.
The unique Direct Mount Design (not SRAM MTB DM compatible) enables a lighter, stiffer, and more durable crankset.
