Ikon Alloy 20" Rim 451x19.5 36H No Brake Surface Neon Yellow

Product Overview The Ikon UltraLite is a 36-hole 20" brakeless BMX racing rim engineered with double-wall 6061-T6 aluminum and optimized internal geometry for maximum lightweight performance. The aero-profile brakeless design works as front or rear rim on disc-brake setups, eliminating weight penalties from brake tracks. At 262g, it's the lightest option in the Ikon lineup. Available in neon yellow with black anodized finish.

Key Features

• Double-Wall 6061-T6 Aluminum Construction – Lightweight yet durable; double-wall design increases stiffness without proportional weight gain, balancing speed and strength for racing applications
• Optimized Internal Geometry – Proprietary IKON design reduces material in non-critical areas while maintaining structural integrity; delivers efficient weight-to-strength ratio critical for 20" racing
• Angled Spoke Holes – Slightly inclined spoke openings create more direct spoke-to-nipple angles, improving load distribution and reducing lateral stress during wheel building and riding
• Low-Profile Aero Design – Minimized rim height and brakeless profile reduce drag and rotational mass; beneficial for acceleration and sprint performance in racing
• Double Polished and Black Anodized Finish – Two-stage polishing creates brilliant reflective surface; black anodized coating resists corrosion and provides durability
• Water Transfer Graphic in Neon Yellow – High-quality graphics applied via water transfer process; won't peel or fade under UV exposure
• Disc-Brake Specific Design – Brakeless profile eliminates brake track, reducing weight and enabling use as front or rear rim on hydraulic or mechanical disc-brake systems without compromise
• Tubeless Ready System – Features bead lock system for tubeless tire compatibility; reduces rotational weight and enables sealant-based puncture repair with tubeless-specific tires and additional components
• Front or Rear Versatility – Same geometry and strength profile allow use on either wheel position without sacrificing performance or durability

Technical Specifications

• Wheel Size: 20" (451mm ETRTO)
• Width: 19.5mm external / 13.5mm internal
• Height: 16.3mm
• Spoke Holes: 36 (drilled)
• Material: 6061-T6 Aluminum
• Rim Profile: Double-walled, brakeless (aero design)
• ERD (Effective Rim Diameter): 434mm
• Valve: Presta F/V
• Finish: Double-polished, black anodized with neon yellow water transfer graphics
• Weight: 262g (9.2 oz)
• Recommended Spoke Tension: ≤115 KGF
• Maximum Tire Pressure: 110 PSI (7.58 bar)
• Tubeless Ready: Yes (requires additional tubeless conversion components: special valve, sealant, rim tape, liquid sealer)
• Brake Surface: None (brakeless / disc-brake compatible)

Compatibility and Ideal Use Cases

• Fits: 20" BMX racing bikes with 36-hole hubs; front or rear wheel positions on disc-brake systems (hydraulic or mechanical)
• Brake System Requirement: Disc brakes only—cannot be used with rim brakes or V-brakes due to lack of brake track
• Tire Compatibility: 20"x1-1/8" or 20"x1-3/8" BMX racing tires; tubeless-specific tires with proper rim tape and sealant for tubeless setup
• Best For: 20" BMX racers with disc-brake bikes seeking maximum lightweight performance; riders prioritizing weight savings and acceleration on modern disc-equipped frames
• Ideal Riders: Intermediate to advanced 20" racers; riders running complete disc-brake setups; competitive racers optimizing for speed
• Wheel Building: Requires 36-hole hub, spokes (20"x1.375" length recommended), nipples, and proper spoke tensioning to 115 KGF or less
• Not Recommended For: Rim-brake or V-brake systems; 24" frames or other wheel sizes; riders unable to maintain proper spoke tension under high loads; setups exceeding 110 PSI tire pressure

Tubeless Conversion Rim is tubeless-ready but requires additional components for full tubeless setup: tubeless-specific valve, sealant rim tape, liquid sealer, and tubeless-compatible tires. Traditional tube setup works without modifications.

Maintenance Note Spoke tension should be verified periodically and maintained at or below 115 KGF to prevent rim stress and spoke breakage. Check wheel trueness before each race. Do not exceed 110 PSI tire pressure.

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.
