Carbon Rims 700C Road Bike Rim Brake 28mm Wide Tubular

Orn728 series carbon rims are made from Premium Toray T700&T800 carbon fiber, We use a double wall design to better control the rim strength and stiffness during layup. and adding additional material around the spoke hole area for reinforcement.

Lightweight, aerodynamic, stiff and strong.

Aero-technical design with U-shaped cross-section. carbon 700C tubular rims 28mm wide outside, with 33/38/44/50/55mm depth options. It can be used as both race carbon rims or daily driver's rims. The 28mm outer width keeps the aerodynamics optimized with smoother rolling for your 25c and 32c tires.

For rim-brake carbon rims, we have UD/Basalt/3K/3K twill/ Grooved 3K twill to choose from. With high TG and faster heat elimination.

FEATURES: 

- U shape design Aerodynamic advantages

- Double wall design, for better strength and stiffness

- High TG 255°C braking surface

- Road rim-brake carbon rims, 28mm width

- 33/38/44/50/55mm depth optional

- 2 years' quality warranty

TECHNOLOGY

1. High TG 255°C Brake Surface

High TG resin temperature 255° brake track, solve the heating problem on the rim brake clincher bicycle wheels.

2. Ultra Smooth Inner Wall

Use specific, thinner, high-pressure air bladders to control the inner wall smoothness, The result is that we could see a very clean and smooth inner wall, which means the carbon fabrics are stretched smoothly and optimized. This could ensure the best strength of the fabrics.

3. Double Wall Design and Aero Technology

We use a double wall design to better control the rim strength and stiffness during layup. Rim profiles are specially designed with aero gains and drag reduction in mind.

4. Customized Spoke Hole Angle Drilling Technology

High-speed CNC machine tools drill carbon fiber rim spoke holes. Customized according to the geometric angle of the hub. Check all drill holes to make sure they are free of burrs.

CARBON 700C RIM BRAKE WITH DIFFERENT BRAKING SURFACES

BRAKE SURFACE:

We have 5 different brake systems for professional cyclists to choose from. The high TG resin temperature of the 255° brake track solves the heating problem on the bicycle wheel of the rim brake. 

If you have special requirements for the brake system, Grooved 3K twill will be your best choice. 

The grooved track helps to evacuate trapped moisture between the brake pad and carbon rim under wet. it bears a higher temperature while braking, but for faster braking heat elimination. More friction, less lever force needed, and shorten about 30% braking distance. More friction to shorten the braking distance.

MANUFACTURING PROCESS:

Our carbon fiber rims are formed in one piece, and each rim is made of long carbon fiber without wrinkles, to make the strength of the rim is the strongest. Every component, including the rim serial number, airbag, and carbon fiber prepreg, is collected, inspected, and weighed to confirm that everything has been taken into account.
