Carbon Fiber Material

Carbon Fiber Material

Premium Toray T700 + T800 carbon fiber are used in our carbon rims. 

Besides, advanced graphene filling technology is used in producing our super light MTB carbon rims (GP model). 

Combining with stable resin system to make consistent quality and light weight mountain bike carbon rims.

Light Weight

Light Weight

By using well designed lay-up structure, mixing Toray T700 and T800 carbon prepreg, light weight carbon rims are created.

Excessive materials are eliminated to save weight, while extra materials are added around spoke hole for reinforcement.

So, light weight is achieved without compromise in strength or stiffness.

Asymmetric Design

Asymmetric Design

Asymmetric design mtb rims help to make wheelset with more even spoke tension between drive side and non-drive side.

Carbon mtb wheels built with asymmetric rims are of better stiffness and stability.

The spoke tension on such wheelset will not get loose easily, lower frequency for re-truing is needed.

Hookless Design

Hookless Design

Compared to bead hook rims, the sidewalls of hookless rims are thicker and stronger, providing better impact resistance.

Straight bead provides more stance for tire. Tires will not be squeezed in bead as it was, which makes it less "light bulb effect".

Thus, the tire/rim engagement is more stable, more difficult to be blown out under strong impact, which is important for carbon mtb rims.

Tubeless Ready

Tubeless Ready

Tubeless tire is getting popular in road bike wheels thanks to its better traction, lower rolling resistance and better riding comfort.

All our carbon clincher rims are tubeless ready (also fit normal tube tires).

Optimized anti-burp bump design provides easy tire mounting, dismounting, as well as air inflation. 

Hand Built

Hand Built

All our carbon wheelsets are hand built by experienced mechanician.

Based on customers’ demand, various choice of hubs, spokes and nipples are optional.

After wheel built, they are trued precisely at high standard (≤0.3mm) on roundness, lateral and center tolerance.

DT240 Boost Hubs

DT240 Boost Hubs

High end DT Swiss 240 EXP Boost hubs, light weight and reliable carbon mountain bike wheels for racing.

Ratchet EXP 36 freehub system provides best reliability. Straight spring and increased bearing distance creates longer lifetime.

15*110/12*148 boost spacing, with both 12-speed (Sram XD, Shimano MicroSpline) and 11-speed freehub optional.

Sapim CX-Ray Spokes

Sapim CX-Ray Spokes

High end Sapim CX-Ray spokes, one of the best spokes available in the market.

CX-Ray spoke is the best combination of light weight, strength, flexibility, and it results in best fatigue testing.

It is widely used in many carbon bike wheels of those top brands all over the world. 

2-Year Warranty

2-Year Warranty

We have strict production management system, QC and Testing process. Our quality is always very good and reliable.
