Ikon Alloy 24" Rim 507×28 36h With Brake Surface

Product Overview

The Ikon UltraLite ETRTO 507 is a lightweight double-wall rim designed for 24" BMX cruiser race wheels. CNC-machined from 6061-T6 aluminum with optimized internal geometry, this 36-hole rear rim weighs 403 grams and features a 28mm width that balances the lightweight characteristics of traditional 1.5" rims with the strength of 1.75" rims. Includes CNC-machined brake surface for caliper or U-brake compatibility.

Key Features

• Optimized 28mm width – Wide enough to provide 1.75" tire support and impact resistance while maintaining weight comparable to narrower 1.5" rim designs

• 6061-T6 aluminum construction – Heat-treated aluminum alloy with proprietary internal geometry removes excess material while maintaining lateral stiffness and impact strength

• Angled spoke holes – Inclined nipple openings create a more direct spoke angle to the hub flange, improving spoke tension distribution and wheel strength

• CNC-machined brake track – Precision-machined sidewalls provide consistent braking performance with caliper or U-brake systems

• Tubeless-ready bead lock system – Integrated bead lock shelf secures tubeless tire beads without additional rim strips when using tubeless-specific tires, sealant, valves, and rim tape

• Double-polished anodized finish – Black anodized surface with water-transfer graphics provides corrosion resistance and visual customization in four color options

• Sleeved rim construction – Reinforced construction method improves rim strength at spoke holes and bead seat areas

Compatibility and Ideal Use Cases

Designed for rear wheels on 24" BMX cruiser race bikes using rim brakes (V-brake, caliper, or U-brake). The 36-hole drilling pairs with standard cruiser cassette or freewheel hubs for strong wheel builds capable of handling Pro and Pro XL class racing demands. Best suited for competitive cruiser racing where riders want the strength and tire support of a wider rim without the weight penalty of traditional 1.75" designs. 507mm ETRTO (24") fits standard cruiser 24" × 1.50" to 1.75" tires. Tubeless setup requires additional components: tubeless-specific tire, Presta valve, rim tape, and liquid sealant (all sold separately). Not recommended for disc brake setups—brake surface adds weight unnecessary for disc applications.

Note: Tubeless conversion requires additional components sold separately: tubeless valve, sealant, and rim tape.
