The Excess "XLC OS20" BMX Race Rim - 20 Inch (451) - 36H - V-Brake is a BMX race double wall rim made of 6061-T6 aluminum with an anodized finish for OS20 bikes. OS20 is not a 22 inch size but a taller and wider 20 inch diameter for more stiffness and less rolling resistance. This rim is the rear profile with a CNC machined brake track for V-brakes. The spoke holes are slightly angled, so the spokes run in more directly and the wheel gets stiffer.
It measures 451x28mm, is 19mm high, weighs 359g according to US Pro and has 36 spoke holes and a Schrader valve hole. Thanks to its bead lock it is tubeless ready, for that you also need a tubeless valve, rim tape, sealant and a tubeless tire.
