The descriptions of carbon rims 40mm tubeless:
The 40mm tubeless carbon rims internal width is 21mm, outer width is 28mm. And the rim provides the perfect balance between aerodynamics, weight. Besides it performance great in windy conditions.
Moreover, the tubeless ready system allows you to easily change to tubeless tires. Thereby reducing rolling resistance and providing better protection against punctures. due to the significant improvements in aerodynamics, weight and stiffness. This rim is a wheel set suitable for all types of terrain.

The features of 40mm deep carbon rims 700C 28mm width.

  • The material of the rim is full carbon Toray T700&T800.Which make the carbon rims lighter.
  • The rim has complex layer structure. No two carbons are the same. The layered structure and orientation of the fibers are decisive for the function and stiffness of the carbon component.
  • The wider carbon rim profile has better lateral rigidity. Besides, more wider rims offers better aerodynamic performance. Together with better handling and faster riding speed in crosswind conditions.
  • The height of the rim profile determines the radial stiffness. The radial load of the rim on uneven ground due to bumps or bottoming will be reduced due to the high profile. There is almost no reduction in the load on the spokes. Which directly increases the life of the structure. Our 40mm high rims are the perfect combination of stiffness, aerodynamic design and weight. Maintain agility and ensure excellent scrolling performance.
  • All spoke angles have customized according to the geometric angle of the hub. All spoke holes have inspected to ensure that they are free of burrs. If your wheel is unique and you want a unique wheel configuration. Then you can request a customized drilling angle.

Why tubeless carbon rims are more and more popular.

  • First, with lower rolling resistance. By eliminating the inner tube, the friction between the tire and the inner tube has also eliminated. This makes the tire rolling, bending and conforming to the road more efficient.
  • Second, it is “Flat less and ride more”. In addition, it can run in the best pressure. With tubeless version rim , you can run the pressure you want for maximum comfort, traction and rolling efficiency.
  • Third, tubeless performance depends on the tire maintain a light press fit with the edge on the diameter of the bead seat.
