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 exclusively from Torray T700s High Modulus Carbon Fiber, they are extremely light, stiff, and strong. Designed for up to 100psi tire pressures. Available in 28 or 36 spoke options.

The Sidewalls are weaved and packed with a special BASALT braking surface. So while we still recommend theCarbon Fiber BMX Brake Pads by Kool-Stop. They are not an absolute necessity, thanks to the stronger brake track.
