Quarq's power meters come from Sram and are equipped with ANT+ and Bluetooth. These Quarq power meters are one of the most accurate power meters on the market. With a maximum deviation of 1.5%, you have a very accurate power meter that measures both legs. The measuring system is built into the spider of the crankset. This gives you good protection and a battery with a somewhat longer life than, for example, Stages.
