Made from Japanese Toray T700 to T1100 carbon fiber, the UD paint treatment not only highlights the carbon fiber texture but also provides scratch and sun protection.

This 45mm lightweight disc brake road rim is made from Japanese Toray carbon fiber cloth for enhanced rigidity and lightweight performance. Its UD paint finish creates a simple carbon texture, balancing durability with visual appeal. Its 21mm internal width is compatible with tires from 23-47cm, making it suitable for a wide range of riding situations. Its 30mm outer width, combined with a 45mm rim depth, provides ample heat dissipation while balancing aerodynamic performance and maneuverability. The 28mm brake track is specifically designed for disc brakes, ensuring stable and rapid braking while minimizing rim damage. Its lightweight design, with a single-turn weight of 360±15g, reduces rotational inertia for more agile climbing and acceleration, making it ideal for both racing and training.

Core Competition Design： A 50mm rim depth improves high-speed cruising by 10% compared to a 45mm rim depth. Its lightweight construction (lap weight: 385±15g) reduces rotational inertia for balanced performance. Dimensional Advantages： The 21mm internal width stably supports tires ranging from 25-47cm. The streamlined 30.5mm outer width creates a low-drag, rounded cross-section when inflated, balancing grip and high-speed stability. The 27.94mm brake track width is designed specifically for disc brakes, providing ample heat dissipation to effectively prevent thermal decay caused by continuous braking and ensure braking safety. Appearance and Craftsmanship： The unique gold marble finish, created through a multi-layer UV curing process, creates a three-dimensional, layered texture. It not only exudes a premium visual quality, but also offers excellent scratch and UV resistance, ensuring long-lasting aesthetics.

R50X26TL-UL: A 50mm deep, 26mm external width, 19mm internal width tubeless-ready carbon road wheel specifically designed for both comfort and speed. *The rim's optimal aspect ratio is designed to balance aerodynamics, maneuverability, and comfort. Compatible with tires from 23-42mm, this wheel offers excellent grip and a smooth ride. It's also lightweight, weighing only 475 ± 15 grams. *Available in both disc and rim brake versions to suit different rider preferences. *Customizable finishes include UD, marble, 12K, and twill.
