Rival D1 Quarq Road DUB Power Meter

What Our Gearhead® Experts Are Saying:

"The Rival D1 Quarq Road DUB Power Meter is the crankset I recommend to riders who want accurate, reliable power data without overhauling their entire drivetrain to get it. The DUB spindle-based design integrates cleanly into a wide range of frames, the AAA battery is user-replaceable and lasts over 400 hours so it is not something you think about until the end of a long season, and the Quarq accuracy is exactly what you expect from the platform regardless of where it sits in the lineup."

Power-based training is the most direct path to measurable improvement on the bike, and the SRAM Rival D1 Quarq Road DUB Power Meter crankset makes that data accessible in a package that fits a wider range of builds than dedicated power meter cranks have historically allowed. The measurement unit is entirely contained within the DUB spindle itself rather than in a spider or separate pod, creating a clean integration that adds less than 40 grams over a standard crankset and eliminates the external hardware that can complicate installation and compatibility.

The DUB-PWR spindle measures left side power and calculates total watts using Quarq's proven methodology, delivering the accuracy and reliability that has made the Quarq platform a benchmark for crank-based power measurement across road cycling. The 46/33t ring configuration covers the full range of road and mixed terrain gearing demands in a 12-speed setup, and the 107 BCD chainring pattern keeps future ring replacement straightforward. A user-replaceable lithium AAA battery delivers over 400 hours of ride time before needing attention, and IPX7 waterproofing rated to one meter for thirty minutes means wet weather and rain riding do not require any additional consideration. Compatible with standard 142mm hub spacing and chainstays under 415mm, the Rival D1 Quarq fits the vast majority of current road disc platforms without adapters or modifications.
