TECHNOLOGY

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.

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.
