IKON ALLOY 20" RIM 406X28 36H WITH BRAKE SURFACE

Product Overview

The IKON UltraLite is a 20" double-wall aluminum rim designed for BMX racing with rim brakes. Built from 6061-T6 aluminum with sleeved construction, a machined brake track, and angled spoke holes, this rim accommodates 20x1.50" or 20x1.75" tires on the standard 406mm bead diameter. The 28mm width provides the tire support of a wider rim while maintaining a light weight comparable to narrower designs.

Key Features

• Double-wall sleeved construction – 6061-T6 aluminum with sleeved seam improves durability at the weld joint and optimized internal geometry balances light weight with strength
• Machined brake track – CNC-machined braking surface provides consistent, smooth contact and improved stopping power for caliper, U-brake, or V-brake systems
• Angled nipple holes – Spoke holes drilled at an angle for more direct spoke alignment, improving spoke tension consistency and wheel stiffness
• 28mm width profile – Offers the tire stability and grip of a wider 1.75" rim at a weight typically associated with narrower 1.5" rims
• Tubeless-ready bead lock system – Internal bead lock profile allows tubeless tire setup when used with tubeless valve, rim tape, and sealant (sold separately)
• Double-polished black anodized finish – Two-stage polishing process followed by black anodizing with water transfer graphics available in four colors (white, neon yellow, red, blue)

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.

Best suited for BMX racers who use rim brakes and want a lightweight, stiff rear wheel with reliable braking performance. The 28mm external width and 23.3mm internal width provide a stable platform for 1.50" to 1.75" racing tires, improving cornering grip and allowing lower tire pressures without tire roll. The machined brake track ensures consistent brake pad contact and modulation at the gate and through technical sections. The tubeless-ready design benefits racers looking to reduce rotational weight and gain puncture protection through sealant, though tubeless conversion requires additional components not included. The angled spoke holes and sleeved construction suit riders prioritizing wheel stiffness and durability under racing loads. 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.
