The Ikon "Groove UD Carbon" BMX Race Rim - 20 Inch (406) - 36H - Disc is Ikon's double wall carbon rim for 20 x 1.50" to 1.75" Pro wheels, made of a combination of Toray T800 and T700 UD carbon. Ikon optimized the internal geometry for strength at a low weight; the rim weighs 300g. The rim bed is wavy, the height changes between 20mm and 26mm. The rim has no brake surface and is for disc brakes only: it works at the front, and at the rear with a disc brake. Thanks to its bead lock profile it 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.
