IKON CARBON 20" RIM 451x22mm 28h

Product Overview

The Ikon Carbon Rim is a 20" (451 ETRTO) carbon fiber rim built with unidirectional Toray T700 carbon and a UD finish. Designed without a brake surface, it's intended for disc brake setups only and is not compatible with rim brakes. At 284g with a 22mm internal width and tubeless-ready construction, it's a lightweight option for racing and performance builds.

Key Features

• Toray T700 unidirectional carbon – High-strength carbon fiber layup in a single direction provides stiffness and impact resistance while keeping weight low
• UD (unidirectional) finish – Visible carbon weave with clear coat; no paint adds unnecessary weight
• No brake surface – Sidewalls are smooth carbon without a braking track; disc brake use only to avoid damage and safety issues from rim brake use
• Tubeless compatible – Rim profile supports tubeless tire setups for lower rolling resistance and reduced pinch flat risk
• 28-hole drilling – Standard spoke count balances strength and weight for racing applications

Compatibility and Ideal Use Cases

This rim is compatible with 20" (451 ETRTO) tires in 1-1/8" to 1-3/8" widths and requires a disc brake hub and frame/fork setup. Not compatible with V-brakes or any rim brake system—attempting to use rim brakes will damage the carbon and create a safety hazard. Works with standard 28-hole hubs and Presta valve tubes or tubeless setups. Ideal for racers and performance-focused riders looking to reduce rotational weight with a carbon wheelset on disc brake-equipped bikes. Can be used front or rear with disc brakes. Maximum spoke tension should not exceed 115 KGF to avoid rim failure.

IKON carbon rims are some of the lightest carbon rims on the market, but strength has not been sacrificed. Made from a T700 unidirectional weave manufactured by Toray, the leader in the field, more resistant than other 3K weaves, all for a featherweight 280g per rim! A comparable alloy rim of the same size / width weighs 350g, which saves you up to 140g for a pair of rims!

Rims without a braking surface can be used as a front rim but also a rear rim when using a disc brake. They are also designed to allow the fitting of a "tubeless" tire (without inner tube), requiring a specific "tubeless" tire, as well as the mounting kit.

IKON rims are offered in a matte finish with glossy UV stickers.

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.

Disc Braking Compatible - Designed to be used as a front rim or a rear rim when using a disc brake.
