IKON CARBON 20" RIM 406X32MM 36H WITH BRAKE SURFACE

Product Overview

The IKON Carbon is a 20" carbon fiber rim designed for BMX racing with rim brakes. Constructed from Toray T700 carbon fiber in a UD (unidirectional) weave with a brake track surface, this rim accommodates 20x1.40" to 20x1.95" tires on the standard 406mm bead diameter. The 32mm width provides increased tire support and stability while achieving a significant weight reduction compared to aluminum rims of similar size.

Key Features

• Toray T700 carbon fiber – High-grade carbon weave provides exceptional stiffness-to-weight ratio and durability, saving approximately 85-90g per rim compared to equivalent aluminum
• 32mm wide profile – Wider rim supports modern racing tires from 1.40" to 1.95", improving cornering stability and allowing lower tire pressures without tire roll
• Brake track surface – Designated braking surface compatible with caliper, U-brake, or V-brake systems (requires carbon-specific brake pads for optimal performance and safety)
• UD carbon weave construction – Unidirectional fiber orientation optimizes strength along critical load paths while minimizing excess material
• Tubeless-ready bead lock system – Internal bead lock profile allows tubeless tire setup when used with tubeless valve, rim tape, and sealant (sold separately)
• Matte finish with gloss decals – Matte carbon surface with glossy water transfer graphics available in four colors (white, blue, red, neon yellow)

Compatibility and Ideal Use Cases

This rim is designed for standard 20" BMX frames using rim brakes—primarily as a rear wheel with V-brakes, though it also works with U-brakes or caliper brakes. The 406mm bead diameter is the standard BMX size used across racing, park, and street bikes. The 36-hole drilling works with standard 36-spoke hubs in various lacing patterns including 2-cross and 3-cross. Note the 377.4mm ERD requires proper spoke length calculation—verify spoke length before ordering or building.

Best suited for competitive BMX racers who use rim brakes and want maximum weight savings without sacrificing strength. The carbon construction saves approximately 180g (6 oz) per wheelset compared to equivalent aluminum rims, reducing rotational weight for faster acceleration. The 32mm width accommodates modern wider racing tires (1.60" to 1.95"), providing improved grip and tire stability at lower pressures. Critical: This rim requires carbon-specific brake pads—standard rubber pads designed for aluminum will overheat the carbon and can cause catastrophic rim failure. The tubeless-ready design allows further weight reduction and puncture protection through sealant, though tubeless conversion requires additional components not included. Carbon rims require careful handling during installation and maintenance—overtightening spokes or using incorrect brake pads can damage the rim. Not recommended for disc brake or brakeless setups—IKON offers a brakeless surface version for those applications.

Tubeless Ready System - Our rims feature a Bead Lock System, needed for the rim to be Tubeless Ready. With the installation of additional items needed you can get the rim ready for tubeless set up, along with the usage of a tubeless specific tire. With a tubeless set up, you can lighten up your wheels, saveing rotational weight, as well as have a sealant inside your tubeless ready tire to help automatically repair small punctures.
Additional items needed to convert to a Tubeless system include Special Valve, Sealant Rim Tape, and Liquid sealer.

V-Braking Compatible - Designed to be used as a rear rim when using a V-brake.
