29er Carbon Rims Best Carbon Trail/AM/DH/EN Series

We use a one-piece layup design to increase fiber continuity and reduce the number of overlapping seams increases the impact strength and helps distribute energy and shock from impacts to the rim. for better dynamic balance.

Orn937-24/Orn938-28 series, We created a 31mm inner width to pair nicely with modern all-mountain tires ranging from 2.3 – 2.6 inches in width. The 31mm inner width assures tires puttheir entire width to the ground and don’t fold over as easily in corners.

Orn937-18-AM/Orn938-28-AM/Orn940-28-AM/EN model carbon 29er rims with asymmetric design.

Asymmetric design helps to equalize the spoke tension between drive side and non-drive side, which makes carbon MTB wheelset stiffer and stabler.

Best carbon MTB 29er rims series are optional in 31/34/37/38/40mm widths to meet different usage of Trail, All Mountain, Enduro, Downhill.

TECHNOLOGY

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. One-Piece Layup Technology

We use a one-piece layup design to increase fiber continuity and reduce the number of overlapping seams increases the impact strength and helps distribute energy and shock from impacts to the rim. for better dynamic balance.

3. 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.

4. Burp Free Technology  

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

5. Asymmetric Rim Profile Design

This design noticeably equalizes spoke tensions between drive and non-drive sides, This would create a stronger and stiffer wheelset, and with fewer fatigue issues.

6. CNC Angle Drilling Technology

High-speed CNC machine tools drill carbon fiber rim spoke holes. Customized according to the geometric angle of the hub. which allows the nipple to pull straight in line with the spoke for reduced stress. this results in fewer broken spokes and nipples.

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.
