Ikon Carbon 20" Rim 451x22mm 36H No Brake Surface

Product Overview The Ikon Carbon is a 36-hole 20" brakeless BMX rim engineered from Toray T700 unidirectional carbon fiber for exceptional strength-to-weight performance. The UD (unidirectional) carbon weave is optimized for vertical load handling, delivering maximum stiffness per gram. At 279g, it represents the lightest option for competitive disc-brake BMX racing. The brakeless profile works as front or rear rim on modern disc-brake systems, enabling complete bike weight optimization.

Key Features

• Toray T700 Unidirectional Carbon – High-modulus unidirectional fiber optimized for vertical load paths; superior stiffness-to-weight ratio compared to multi-directional weaves; reduces rotational mass for acceleration and responsiveness
• UD Finish – Unidirectional fiber orientation visible in finish; provides clean aesthetic and indicates performance-focused carbon construction
• 36-Hole Configuration – Standard spoke count for BMX racing; maintains adequate spoke redundancy and load distribution despite ultra-lightweight rim
• Brakeless Front Profile – Designed specifically for disc-brake systems; eliminates brake track weight and complexity; enables clean, minimal rim design
• Low-Profile Aero Design – Minimized rim height (23.35mm) reduces drag and rotational mass; beneficial for acceleration and sprint performance in racing
• Disc-Brake Compatible – Brakeless profile enables use as both front and rear rim on hydraulic or mechanical disc-brake systems without compromise
• Angled Nipple Holes – Spoke openings optimized for direct spoke-to-nipple angle, improving load distribution and wheel rigidity
• Tubeless Compatible – Ready for tubeless tire setups; 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: 22mm external
• Height: 23.35mm
• Spoke Holes: 36 (drilled)
• Material: Toray T700 unidirectional carbon
• Rim Profile: Brakeless (front/rear disc)
• ERD (Effective Rim Diameter): 426mm
• Valve: Presta F/V
• Finish: UD (unidirectional carbon visible)
• Weight: 279g
• Recommended Spoke Tension: ≤115 KGF
• Maximum Tire Pressure: 110 PSI (7.58 bar)
• Tubeless Compatible: Yes (requires tubeless-specific components: valve, tape, sealant)
• Brake Surface: None (brakeless / disc-brake compatible)

Compatibility and Ideal Use Cases

• Fits: 20" BMX 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 and unidirectional carbon orientation
• Tire Compatibility: 20"x1-1/8" or 20"x1-3/8" BMX tires; tubeless-specific tires with proper components for tubeless setup; maximum inflation 110 PSI
• Best For: Elite BMX racers with disc-brake bikes prioritizing absolute lightweight performance; competitive riders seeking maximum weight advantage and versatile front/rear compatibility
• Ideal Riders: Expert-level 20" racers; riders running complete disc-brake setups; competitive racers optimizing for speed; those valuing weight savings and high-modulus carbon performance
• Wheel Building: Requires 36-hole hub, spokes, and nipples to complete wheel assembly; professional wheel building strongly recommended due to carbon's brittleness and unidirectional properties
• Not Recommended For: V-brake or rim-brake systems; riders exceeding 110 PSI tire pressure; rough or loose track surfaces; beginners unfamiliar with carbon care; casual or recreational riders

Tubeless Setup Rim is tubeless-compatible but requires additional components: tubeless-specific valve, rim tape, sealant, and tubeless-compatible tires. Traditional tube setup works without modifications.

Maintenance and Care Notes Unidirectional carbon is sensitive to lateral impacts due to single-fiber orientation. Spoke tension must be maintained at or below 115 KGF to prevent rim stress and potential cracking. Check wheel trueness before each race. Do not exceed 110 PSI tire pressure. Store and transport rim carefully in padded wheel bag to avoid direct impacts. Inspect regularly for cracks or damage. Front and rear versatility allows wheel swaps between positions if one requires inspection or repair. Professional wheel builder recommended for initial build and any future truing or spoke adjustments.

IKON carbon rims are some of the lightest carbon rims on the market, but strength has not been sacrificed. Made from a T700 unidirectional weave manufactured by Toray, the leader in the field, more resistant than other 3K weaves, all for a featherweight 280g per rim! A comparable alloy rim of the same size / width weighs 350g, which saves you up to 140g for a pair of rims!

Rims without a braking surface can be used as a front rim but also a rear rim when using a disc brake. They are also designed to allow the fitting of a "tubeless" tire (without inner tube), requiring a specific "tubeless" tire, as well as the mounting kit.

IKON rims are offered in a matte finish with glossy UV stickers.

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.
