Speedline Parts | RCR / 520 - 24 x 1 1/8" Carbon Fiber Rim

The Speedline RCR Rims are some of the lightest BMX Race Rims on the market. Featuring a stout, low-profile, aggressive design that ensures a proper contact patch for your tire while retaining maximum stiffness.

Built from Torray T700S High Modulus Carbon Fiber, they are extremely light, stiff, and strong. Designed for up to 100psi pressures. Available in 24 or 28 spoke options.

The Sidewalls are weaved and packed with a special BASALT braking surface. While we still recommend the Carbon Fiber BMX Brake Pads by Kool-Stop. They aren't an absolute necessity, thanks to the tougher braking surface.

The Speedline RCR 520 Carbon Fiber BMX rims accept 24x1, 24x1 1/8", and 24x1 3/8" tires.

The ERD of the Speedline RCR 520 rim is 484.1mm.

The Speedline RCR 520 Carbon Fiber BMX Rims are tubeless compatible. While there aren't many Tubeless BMX Specific tires, the Speedline RCR 520 carbon fiber rims are forward-thinking and built to last you as long as you are racing BMX.
