The Ikon "UD Carbon" BMX Race Rim - 20 Inch (451) - 36H - V-Brake is Ikon's carbon rim with 36 holes for 20 x 1-1/8" and 20 x 1-3/8" tires, meaning a 451mm bead seat diameter. It is made of unidirectional Toray T700 carbon, which Ikon says is stronger than common 3K weaves. The aero profile is 22mm wide and 23.3mm high, the nipple holes are angled.
The sidewalls have a brake track, so this is Ikon's rear profile for V-brakes. On a carbon rim you must use special carbon brake pads. 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. It is tested by the Chase race team. Ikon recommends at most 7.58 bar (110 psi) and a spoke tension up to 115 kgf.

Carbon rim notice
On carbon rims, single layers of the laminate can crack, usually from hard landings or overloading. Such damage from use is not a defect: it is covered neither by the statutory warranty nor by any manufacturer's warranty. A rim with cracked layers should be checked before it is ridden again.
Our recommendation: carbon rims are best suited to experienced, professional use. Front wheel rather than rear, and park, dirt or race rather than street. Land clean and you keep the weight advantage for longer. Worth being aware of.
