SRAM Rival AXS D1 Quarq DUB WIDE 172.5mm 43/30T Yaw Road Power Meter

Train Smarter, Ride Faster
Training with a power meter is one of the best ways to improve your overall speed and endurance. A power meter allows the rider to accurately gauge efforts and measure performance. This is critical for riders looking to get faster. The power meter from Quarq offers unparallel performance.
DUB Bottom Bracket (NOT Included) Compatible
DUB is a ground up bottom bracket design that has been built to promote better integration between the entire drive chain. The idea is a complete system the results in excellent shifting and fast lap times. DUB also improves stiffness without sacrificing durability.
Power Becomes More Affordable
Power every ride. SRAM have taken the reliability, elegance and features of Quarq's legendary crank-based power meter and dropped the barrier to entry once again. This new power meter platform is entirely contained within the DUB spindle for clean integration that fits more bikes than ever.
Elegant Intergrated Design
The DUB-PWR spindle based unit is fully contained inside the spindle. It measures left side power to calculate total watts. Having the "electronic smarts" fully enclosed improves reliability and robustness. No more bulky crank or pedal add-ons. The total weight of this unit is only 40g heavier than the standard crank set, you won't even know it is there.
Long Battery Life
The massive 400+ hour battery life will power a season of rides. This almost "set and forget" unit takes AAA lithium batteries which are user replaceable. There is no need to send this power meter back to the factory just to replace the battery. This unit has an IPX7 waterproof rating which means it can be submerged to a depth of 1 meter for up to 30 mins with no problems.
