Quarq Powermeter Upgrade Rival AXS 170mm Wide Left Crankarm 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 shaft-based DUB-PWR unit measures the power on the left side to calculate the total wattage. Longer DUB crankshaft fits both road and MTB frame bottom bracket standards for unmatched cross compatibility across all brands.

SRAM's Rival Wide DUB Upgrade Kit, a crank arm with power meter axle, allows left-side power measurement on any bike with a Rival Wide DUB crankset.
