SRAM RED AXS E1 POWER METER KIT It’s the ultimate in integrated power measurement. The RED AXS power meter kit adds Quarq technology to our one-piece chainrings for the lightest, stiffest, and most accurate power package available. A 13-tooth delta on all chainring pairs ensures precise shifting for any setup, as well as a less dramatic change in cadence during front shifts. Combined with our most durable chainrings ever, it’s an unbeatable combination.
