Know before you buy
No, the Red E1 Aero Chainring Kit is specifically engineered for integration with the SRAM Red eTap AXS drivetrain. It is not designed for compatibility with older mechanical or non-AXS electronic groupsets.
The specialized aero profile is shaped to reduce aerodynamic drag at higher speeds. This helps you maintain momentum more efficiently, making it an ideal upgrade for time trials, competitive road racing, or fast-paced group rides.
The 48t option offers a slightly lower gear ratio, which can be beneficial for hilly terrain or maintaining a higher cadence. The 50t option provides a larger gear range, favoring top-end speed on flatter courses.
Yes, the kit is designed to work in harmony with the SRAM Red eTap AXS ecosystem to ensure crisp, reliable gear changes. By using components engineered to work together, you minimize the risk of chain drops and hesitation during shifts.
Installation requires standard cycling tools compatible with SRAM Red AXS cranksets. If you are comfortable performing your own drivetrain maintenance, the process is straightforward, though we recommend consulting the official SRAM service manual for torque specifications.
