Ikon Alloy 20" Rim 451x19.5 36H With Brake Surface Neon Yellow

Product Overview The Ikon UltraLite is a 36-hole 20" BMX racing rim engineered with double-wall 6061-T6 aluminum and optimized internal geometry for lightweight performance. The CNC-machined brake track delivers consistent stopping power for V-brake or mechanical disc-brake setups. Angled spoke holes improve load distribution for stronger, more rigid wheel builds. 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
• CNC-Machined Brake Track – Precision-finished braking surface ensures consistent pad contact and superior stopping power compared to non-machined surfaces; critical for race reliability and modulation
• Aero-Profile Design – Optimized rim height and shape 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
• 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
• V-Brake Compatible – Brake track design supports traditional V-brake systems; rear wheel-specific for compatibility with standard BMX race bikes

Technical Specifications

• Wheel Size: 20" (451mm ETRTO)
• Width: 19.5mm external / 14.6mm internal
• Height: 16.3mm
• Spoke Holes: 36 (drilled)
• Material: 6061-T6 Aluminum
• Rim Profile: Double-walled with CNC-machined brake track
• ERD (Effective Rim Diameter): 434mm
• Valve: Presta F/V
• Finish: Double-polished, black anodized with neon yellow water transfer graphics
• Weight: 285g (10 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: CNC-machined for improved stopping power

Compatibility and Ideal Use Cases

• Fits: 20" BMX racing bikes with 36-hole hubs; rear wheel position with V-brake or mechanical disc-brake systems
• 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 seeking lightweight, high-performance wheels; riders balancing speed with braking reliability for competitive racing
• Ideal Riders: Intermediate to advanced 20" racers; riders prioritizing acceleration and brake performance on traditional V-brake setups
• 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: 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.

V-Braking Compatible - Designed to be used as a rear rim when using a V-brake.
