The Speedline RCR Rims are some of the lightest BMX Race Rims on the market. They utilize the only BMX specific Pro Size rim design currently on the market. It is a stout, low profile, aggressive design that ensures a proper contact patch for your tire and the maximum stiffness while allowing you to lose crucial rotating weight.
Built exclusively from Torray T700 and T700s High Modulus Carbon Fiber, they are extremely light, stiff and strong. Designed for up to 100psi pressures. Available in 28 or 36 spoke options.
The Sidewalls are weaved and have a special BASALT Braking surface, so while we still recommend the Speedline Carbon Fiber BMX Brake Pads by Kool-Stop. They are not an absolute necessity.
The Speedline RCR 406 Carbon Fiber BMX rims accept 20x1.4, 20x1.5, 20x1.6 , 20x1.75, 20x1.8, 20x1.95, 20x2.0, and 20x2.125 tires.
28h are drilled for Presta Tubes while the 36h are set to accept Presta or Std. Schrader Valves.
We have had a lot of people asking for the ERD and Spoke Length. The ERD of the Speedline RCR 406 rim is 379mm.
We have laced the 36h ONYX Racing hubs up in our Speedline rims with the US Spoke Titanium Spokes in a 4x pattern with 184mm spokes and the 16mm Alloy Nipples.
The Speedline RCR 406 Carbon Fiber BMX Rims are tubeless compatible. While there may not be many Tubeless BMX Specific tires, the Speedline RCR 406 carbon fiber rims are looking towards the future to last you as long as you are racing BMX.
Stock Colors are Gloss Carbon ( Black ) w/ 2 tone Silver and White Graphics or White w/ 2 tone Silver and Black Graphics.
