SRAM Rival D1 DUB Wide Left Crank Arm and Power Meter Spindle 170mm

Measure Every Watt
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. This means more people can now train with precision and accuracy. This new power meter platform is entirely contained within the DUB spindle for clean integration that fits more bikes than ever. It’s invisible technology that adds minimal weight and will help you get to the finish line faster, and can be used to upgrade any eTap AXS bike to power.
