This is achieved by utilizing what SRAM calls “DUB-PWR” – a unique design that elegantly houses Quarq’s reliable and accurate power measurement inside the DUB crank spindle itself. Measuring left-side power to calculate total watts, it’s subtle, lightweight, compatible with any chainring setup, and boasts an extra long battery life. It is also compatible with the RockShox Flight Attendant system, allowing for total connectivity between all AXS™ enabled components. No-compromise, no-fuss data delivery giving you an edge over the competition.
