1x aero road crankset
SRAM RED AXS E1 1x Aero Crankset

Highlights
Why we rate it
Aero chainring
The large, smooth-faced ring is shaped to clean up airflow around the drive side, aimed at TT and fast 1x road setups.
Integrated power option
The power version hides the strain gauges in the chainring and reports both legs plus left-right balance.
RED carbon arms
Same hollow carbon arms as the 2x RED E1 crank, with the latest lighter construction.
Works with 12 or 13-speed
Designed for SRAM's 1x road drivetrains, including the 13-speed RED XPLR and Force XPLR set-ups.
