Quarq Powermeter Upgrade Rival AXS 175mm Left crank arm and Powermeter spindle

Power on every ride. We've taken the reliability, elegance and features of Quarq's legendary shaft-based power meter and lowered the barrier to entry once again. This new power meter platform is fully housed within the DUB shaft for a clean integration that fits more bikes than ever before. It's an invisible technology that adds minimal weight and helps you get there faster. It can be retrofitted to any eTap AXS bike with power. The wave-based DUB-PWR unit measures the power on the left side to calculate the total wattage.

The Rival DUB Upgrade Kit from SRAM, a crank arm with power meter axle, enables left-side power measurement on any bike with a Rival DUB crankset.
