The SRAM Red AXS E1 Power Kit 2x, Power Meter Crankset Chainring Combo is 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 robust chainrings ever, it’s an unbeatable combination.

Features:

• X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
• Power meter is fully integrated into the chainring for lighter weight
• Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
• Measures right and left leg power balance
• Crisp and accurate front shifts
• Unique chainring shape results in a lighter weight, stiffer, more durable unit
• Available in 46/33T, 48/35T, 50/37T, 52/39T, 54/41T, and 56/43T chainring combos
