SRAM RED E1 1x Aero Road Chainring

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.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
