SRAM Chainring Red AXS E1 Powermeter 52/39 DM BK/SL (SKU 212538)

The SRAM Red AXS power meter kit adds Quarq technology to one-piece chainrings. A 3-tooth delta on all chainring pairs ensures precise shifting, and X-Range gearing gives you more range and a smoother gear progression. Readings are accurate within +/-1.5% and aren't affected by climate conditions, and the system measures right and left leg power balance. Pairs range from 46/33 to 56/43, in black and silver.
