Sram Red AXS E1 Power Meter Direct Mount 2x12v chainrings

It's the ultimate in integrated power measurement

The RED AXS power meter kit adds Quarq technology to one-piece gears for the lightest, stiffest and most accurate power package available on the market. A 13-tooth delta across all gear pairs ensures precise shifting for any setup, as well as less drastic variation in cadence during front shifts. Combined with the strongest gears ever, it's an unbeatable combination.
