SRAM RED E1 1x Aero Road Chainring
Couldn't load pickup availability
The SRAM RED E1 1x Aero chainring is designed for road bikes with a single front chainring, and is the choice for riders seeking an aerodynamic profile for time trials and triathlons. The X-SYNC tooth profile, with alternating wide and narrow teeth, aims to offer maximum chain control, while the laser-etched finish is more durable over time.
The X-Range system expands the gear range and makes shifting progression more consistent. The model is made from aluminium, with direct mount attachment, and is suitable for 12/13-speed drivetrains. It is available with 46, 48 or 50 teeth, in black and silver, so your choice concerns tooth count and compatibility with your drivetrain.
