Carbon Rim 650B Gravel 30mm Wide

We use a double wall design to better control the rim strength and stiffness during layup.

The latest Gravel/Adventure carbon 650B rim has been designed with a specific new rim profile. The main feature of these wheels is to make it perfect for the focused purpose of drop-bar adventure/gravel road riding.

30mm wide outside and 25mm wide inside rims provide excellent ride handling and support for the wider tires.

They work perfectly with the 2.2 inch mountain bike tires. Using larger tires results in better bump compliance, greater flat protection, and more grip.

Tubeless feature reduces weight and rolling resistance and features an H-lock bead seat for easy and secure tubeless mounting.

Ultra-light carbon gravel 650B rims make this the perfect choice for adventure/gravel riding. Pro Racing level, lightweight, stiff and durable, perfect for your gravel and cross-country bikes. If your frame has enough space, these wheels can allow you to drive on rough terrain.

650B Carbon Gravel Rims Series of Standweight / Flyweight

1. Advantages of Hookless Sidewalls

The bead of the hookless rim is straighter and smoother, and the tire can fully contact the rim wall. Compared with traditional hook rims, it is more durable and impact resistant. Provide more support during sharp turns.

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. Burp Free Technology  

When the tire is mounted, the raised portion reinforces the tire bead, making it harder to burp into the center channel.

4. 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.

5. 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.

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.
