Quarq Power Meter Spider Red AXS D1 107BCD

Quarq Power Meter Spider Red AXS D1 107BCD Light and accurate; the 107 BCD Quarq Power Meter Spider Red AXS D1 allows dual-sided power measurement to be added to existing SRAM RED AXS and Force AXS chainsets by simply replacing the spider. The power meter is accurate to +/-1.5% regardless of changing temperature conditions during the ride and uses a commonly found CR2032 battery that lasts for 200 hours of riding. Battery replacement is a tool-free operation so it can even be done mid-ride. As the device is AXS enabled it connects to the SRAM AXS smartphone app for easy monitoring and firmware upgrades.
