650B rims

CHA/Customized spoke hole angle

All spoke hole angles must be customized according to the geometric angle of the hub.all drilled holes are inspected to ensure they are free of burrs.You can request a customized drilling pattern if you have a unique wheel build.

TRD/Tubeless R angle design

All yuan an bike are tubeless compatible.We design a R angle,The rounded edge makes tire installation easier and offers increased support during hard cornering with a softer edge and larger surface area.

LMS/lighter materials improve the strength

We use lighter materials and make full use of the combination of T700 and T800 to improve the strength.

SIW/smooth Inside Wall

We use a specific, thinner, high-pressure air bladders to control the inner wall smoothness, and the inner wall air bladders can be extracted clean at one time, without residue, not only effectively improve the tightness of the carbon fiber yarn, but also allow the spoke cap to be more tightly integrated with the spoke hole

OPT/one piece technology

Compared to the technology of 3 piece, our one piece tech is more technically difficult and takes longer to produce, but the rigidity of the rim is at least 7% higher

BLT/Bead Lock technology

The bump on the rim bed helps to create a buffer during tire inflation, making the mounting process easier. When the tire is mounted, the raised portion reinforces the tire bead, making it harder to “burp” or fall back into the drop channel.

Design your brake surface?

Basalt brake surface or crystal polishing brake surface.

What is the role of basalt braking surface?

Basalt is a special carbon fiber material, the surface is rough and high temperature resistance, wear-resistant.

Basalt has a good performance, both on dry and wet roads.

What is the difference between UD, 3K, and 12K Weaves?

The weave patterns you see on some of our rims are only the external layer and are done for cosmetic reasons.

This layer utilizes the same resin system as the rest of the rim and so the weight and performance are not significantly changed. UD is the most popular option.

What is the role of crystal polishing brake surface?

Crystal polishing is a special technology, in the final steps of the machining rim, we use crystals to polish the surface of the braking surface, so that the surface of the braking surface has better flatness, thus increasing the wear resistance of the brakes, also effectively avoid the noise when braking. Crystal Polishing is only a technology, not a specific individual refers to a type of braking surface, ud/3k/6k/12k braking surface all can be used with crystal polishing this technology .
