Power every ride
SRAM has taken the reliability, elegance, and features of Quarq’s legendary crank-based power meter and dropped the barrier to entry. 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.
