This rim features a 60mm aerodynamic frame with a perfect ratio of 28mm external width to 21mm internal width. Its sleek profile reduces high-speed drag while precisely adapting to 23-47mm tubeless tires. Its bead-shaped design fully complies with ETRTO standards, eliminating the need for an inner tube and ensuring a tight seal verified by thousands of pressure tests. Its ultra-light weight of 450±15g is achieved through the optimized layup of Toray's premium carbon fiber fabric, combined with the factory's patented one-piece molding technology, achieving a perfect balance of rigidity and lightweight.

Product Features and Advantages

Aerodynamic Upgrade: 

The 60mm rim depth, optimized through wind tunnel testing, further reduces high-speed drag compared to a 55mm rim depth, increasing cruising speed and making it suitable for both flat-road racing and long-distance cycling.

Wide Compatibility: 

The 21mm internal width accommodates tires ranging from 23-47cm. The 30mm external width creates a streamlined shape, and when inflated, the tire offers low drag, ensuring both grip and stability.

Reliable Braking: 

The 28mm brake track, designed specifically for disc brakes, provides ample heat dissipation, preventing thermal decay during continuous braking and ensuring safe braking.

Lightweight and Agile: 

The lightweight design, with a single-turn weight of 450±15g, reduces rotational inertia, ensuring agility and agility when climbing and accelerating.

Durable Exterior: 

The UD paint finish features a distinct carbon fiber texture and undergoes a multi-layer UV treatment for scratch and UV resistance, combining a minimalist aesthetic with the durability to withstand heavy use.

Strict Quality Control:

KOBIKE do 100% tire pressure(150 PSI), flatness(＜0.2mm) and roundness(＜0.2mm) inspections before shipping, also offering 2 years warranty for our carbon rims.

Product Structure

Valve Hole Details: 

Precision drilling ensures seamless valve installation, ensuring long-term airtightness and simplifying operation. The 21mm internal width is compatible with tires sized 23-47cm, allowing for tool-free daily inflation and maintenance.

Aerodynamic Sidewall Advantage: 

The 60mm high sidewall is optimized for aerodynamics, creating a smooth transition to the 28mm external width, reducing airflow turbulence at high speeds. The UD paint finish preserves the pristine carbon fiber texture while providing enhanced wear resistance and extending the life of the exterior.

Vacuum-Sealed Design: 

The hidden sealing groove complements the 21mm internal width, allowing for more even distribution of sealant within the groove, significantly reducing the risk of tubeless tire deflation and reducing post-puncture maintenance time by approximately 30% compared to traditional tube-based systems.

Improved Structural Rigidity: 

The reinforced spoke holes enhance the rim's torsional resistance. Combined with the rigid support of the 28mm brake track, this minimizes rim deformation during braking, providing more direct braking feedback and improving safety during emergency braking.

Main Material Performance: 

Japan Toray's carbon fiber lamination process results in a single lap weight of just 450±15g. This lightweight design offers significant acceleration advantages. Furthermore, the high strength of carbon fiber ensures the rim remains stable even at 120psi tire pressure, achieving a perfect balance between performance and durability.

Application Areas

Application areas for the D60X28TL-UL carbon bicycle rim:

For daily training and leisure riding: 

The convenient valve port installation and tire compatibility allow for quick inflation and a smooth ride.

Flat racing and time trials:
