RACE ONE VELLAR Carbon TT Disc wheels

Key Features: Engineered for TT & Triathlon Excellence

• TT-Optimized Aerodynamic Profile: The rear rim features a streamlined 26mm external / 21mm internal width with a hooked tubeless ready design, paired with a front rim tuned for seamless airflow integration. This combination cuts through headwinds, reduces turbulence, and maintains stable aerodynamic performance in all wind conditions.
• Ultra-High Modulus Carbon Construction: Crafted with Toray T700, T800, and T1100 carbon fibers, the VELLAR achieves exceptional stiffness for instantaneous power transfer, superior structural strength for high-speed descents, and a lightweight build that enhances acceleration and reduces rotational mass.
• Featherweight Performance: At just 970g for the complete wheelset, it stands out as one of the lightest TT disc wheelsets available. The reduced weight translates to faster acceleration, less fatigue during long efforts, and the ability to maintain speed with minimal energy expenditure.
• Premium Hub & Bearing Technology: The rear hub boasts RACE ONE’s Low Flange Road Hub (12×142mm, 19mm OD) paired with a Ratchet 54T system, delivering near-instant power engagement for explosive starts and consistent pace. S&S Ceramic Bearings eliminate friction, ensuring smooth, efficient rotation mile after mile.
• Tubeless & Insert Compatible: Supports tubeless tire setups to lower rolling resistance, enhance puncture protection, and allow for lower tire pressures (improving grip on variable TT courses). Rim insert compatibility adds extra durability for rough training roads or technical race segments.
• Disc Brake Optimization: Designed exclusively for disc brakes, offering precise stopping power, consistent heat management, and reliable performance in wet or dry conditions—critical for high-speed TT and triathlon scenarios where control is as important as speed.

Technical Specifications

Compatibility & Use Cases
