Sram Quarq Power Meter Kit DM Red AXS D1 - Includes Chainrings PMQ8228000

Quarq Powermeter Kit DM Red AXS D1 - Includes Chainrings The Quarq 12-speed Power Meter Kit DM Red AXS D1 uses a Quarq DZero power meter integrated into the SRAM direct mount chainrings to provided power measurement accurate to within +/- 1.5%. This integration means that the power measurement doesn’t suffer from ‘drift’ in the way that other devices do, so the best possible accuracy is assured. The kit includes the chainrings which are a single-piece design for greater stiffness and better shifting. The chainrings maintain a 13 tooth gap in all ratios which also improves shifting and aids durability. SRAM claims that their new manufacturing process and materials mean that the chainrings last 50% longer than previous RED chainrings. The eight bolt direct mount rings only fit the new RED and Force eTap AXS cranks, and aren’t backwards compatible.
