Power on every ride. We have taken the reliability, elegance, and features of Quarq's legendary spindle-based power meter and lowered the entry barrier even further. This new power meter platform is fully integrated into the DUB spindle to ensure a clean fit that works with more bikes than ever before. It is an invisible technology that adds minimal weight and helps you reach your destination faster. The spindle-based DUB-PWR unit measures power on the left side to calculate total wattage. The crankset features a wide chainline for bikes with the widest gravel tires. The longer DUB crank arm fits both road and MTB frame bottom bracket standards for unmatched cross-compatibility across all brands.
