Ikon Carbon 20" Rim 406x32mm 32H No Brake Surface

Product Overview The Ikon Carbon is a 32-hole 20" brakeless BMX rim engineered from Toray T700 unidirectional carbon fiber for exceptional strength-to-weight performance. The wide 32mm profile accommodates multiple tire sizes while the brakeless design works on modern disc-brake systems. At 300g, it saves up to 90g compared to equivalent alloy rims (390g baseline). The UD carbon construction and premium Toray T700 material represent the latest in high-end BMX rim technology.

Key Features

• Toray T700 Unidirectional Carbon – Premium high-modulus unidirectional fiber optimized for vertical load handling; superior stiffness-to-weight ratio; reduces rotational mass for acceleration and responsiveness
• UD Carbon Fiber Weave – Unidirectional fiber orientation optimized for BMX racing loads; visible in matte finish aesthetic
• 32-Hole Configuration – Accommodates 32-hole hubs; adequate spoke count for load distribution while maintaining lightweight design
• Wide 32mm Profile – Generous rim width accommodates multiple tire sizes (1.40" to 1.95"+); provides stable tire seating and improved lateral support during cornering
• Brakeless Design – Eliminates brake track weight and complexity; enables use as front or rear rim on hydraulic or mechanical disc-brake systems without compromise
• Matte Finish with Glossy Water Decals – Premium aesthetic combining understated matte carbon with vibrant glossy graphics; available in white, blue, red, or neon yellow
• Presta Valve Compatible – Engineered for Presta valve tubes; narrow valve design standard for modern BMX wheels
• Tubeless Compatible – Ready for tubeless tire setups (requires tubeless-specific tire and preparation kit); reduces rotational weight and enables sealant-based puncture repair
• Front or Rear Versatility – Brakeless profile enables use on either wheel position without sacrificing performance or durability
• Significant Weight Savings – 300g delivers 90g savings versus alloy equivalent (390g); complete set saves up to 180g (6.3 oz) per wheel pair

Compatibility and Ideal Use Cases

• Fits: 20" BMX bikes with 32-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: Accommodates multiple tire widths from 1.40" to 1.95"+; enables riders to switch tire sizes without rim changes
• Best For: Competitive 20" BMX racers with disc-brake bikes seeking absolute lightweight performance with wide-tire capability; riders valuing Toray T700 premium carbon quality
• Ideal Riders: Advanced 20" racers; riders running complete disc-brake setups; competitive racers optimizing for speed and weight advantage; those prioritizing minimal rotational mass
• Wheel Building: Requires 32-hole hub, spokes, and nipples to complete wheel assembly; professional wheel building strongly recommended due to carbon brittleness
• Not Recommended For: V-brake or rim-brake systems; front wheel use on rim-brake frames; rough or loose track surfaces; beginners unfamiliar with carbon care

Tubeless Setup Rim is tubeless-compatible but requires additional components: tubeless-specific tire, rim tape, sealant, and tubeless preparation kit. Traditional tube setup with Presta valve tubes works without modifications.

Weight Advantage Brakeless design saves additional weight compared to brake-surface version (300g vs. 305g). Complete set of Ikon Carbon brakeless rims (front and rear, 32-hole) saves approximately 180g (6.3 oz) versus equivalent alloy rims—a meaningful advantage in competitive racing where acceleration and handling response directly impact performance.

Maintenance and Care Notes UD carbon construction is sensitive to lateral impacts due to unidirectional fiber orientation. Store and transport rim carefully in padded wheel bag. Inspect regularly for cracks or damage. Do not subject to extreme impacts or heavy dropping. Professional wheel builder recommended for initial build and any future maintenance. Spoke tension must be carefully managed; consult builder for proper tension specifications. Front and rear versatility allows wheel swaps between positions if one requires inspection or repair.

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.
