The Ikon "Ultralite OS20" BMX Race Rim - 20 Inch (451) - 36H - V-Brake is Ikon's aluminum rim in the OS20 format for 20 x 1.50" to 1.75" tires. OS20 is not a 22 inch wheel but a 20 inch wheel with a larger 451mm bead seat diameter: taller and bigger, which Ikon says makes it stiffer with less rolling resistance than the conventional 20 inch size. It is a double wall 6061-T6 aluminum rim, double polished and black anodized, with water transfer graphics. The sidewalls have a CNC machined brake track, so this is the rear rim for V-brakes. The nipple holes are slightly angled so the spokes sit straighter in the nipples for a stiffer wheel. Thanks to its bead lock profile the rim is tubeless ready; for that you also need tubeless rim tape, a valve, sealant and a tubeless tire. Ikon recommends at most 7.58 bar (110 psi) and a spoke tension up to 115 kgf.
