Ikon Alloy 20" Rim 451x19.5 28h No Brake Surface

Ikon Alloy 20" Rim 451x19.5 28H – No Brake Surface

Product Overview

The Ikon UltraLite is a lightweight double-walled 6061-T6 alloy rim designed for BMX racing with brakeless surface profile. At 266g (9.34 oz), it provides optimized geometry for minimal weight and strength, featuring angled spoke holes for rigid wheel builds and tubeless compatibility.

Key Features

• Double-Walled 6061-T6 Aluminum – Optimized internal geometry reduces weight while maintaining strength for racing applications
• Brakeless Aero Design – Front profile without brake surface; optimized for speed-focused builds without rim brake compatibility
• Angled Spoke Holes – Slightly inclined openings create more direct spoke angle for stronger, more rigid wheel builds
• Double-Polished Finish – Hi-polish surface treatment creates brilliant shine before anodizing
• Black Anodized Coating – Durable protective finish resists corrosion and wear
• Water Transfer Graphics – Four color options (white, neon yellow, red, blue) applied to black anodized surface
• 19.5mm Width – Compact rim width optimized for minimal weight while maintaining tire support
• Tubeless Ready – Bead lock system supports tubeless setup with additional tape, valve, sealant, and sealer (sold separately)
• Front or Rear Compatible – Brakeless design allows use as front or rear wheel without disc brake requirements
• Ultra-Lightweight – 266g (9.34 oz) weight ideal for weight-optimized racing builds

Build Requirements & Compatibility

• Spoke Compatibility – Use with butted or bladed steel spokes; verify spoke length based on hub flange geometry (approximately 220–240mm range depending on hub)
• Spoke Tensioning – Use calibrated spoke tension meter; maximum 115 kgf spoke tension
• Lacing Patterns – Angled spoke holes support standard cross lacing; radial lacing not recommended
• Tire Compatibility – Designed for 20" BMX tires; verify tire bead diameter matches 451 ETRTO standard

• Tire Pressure Limit – Maximum 110 PSI; exceeding this may damage rim or tire
• Tubeless Setup – Requires tubeless-specific tire, rim tape, valve, sealant, and liquid sealer for conversion
• Hub Compatibility – Works with any 28-hole hub (front or rear); verify ERD and spoke hole count

Compatibility & Ideal Use Cases

• BMX racing – Lightweight, aerodynamic design optimized for racing performance
• Weight-optimized builds – 9.34 oz weight ideal for competitive racing setups
• Front or rear wheels – Brakeless design suitable for both positions without brake requirements
• Disc brake systems – Compatible with front and rear disc brake setups (alternative to brakeless use)

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.
