About the yuan an 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 rims 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.

URT/Unique resin technology

To improve the stability of the wheel, we think the material control is the root.So we import carbon fiber raw yarn from Toray, Japan, and mix with the high-temperature-resistant resin which researched and developed by our own, weaving them to be prepreg .So, from the source we firmly control the quality.

EPT/Environmental protection technology demoulding

Compared with many oil-based mold release agents, we use a neutral mold release agent imported from Germany, because we use labeled "NAK80 steel", which is a very high-strength abrasive tool, compared to ordinary P40 For steel, NAK80 has a firmer surface and a smoother rim surface.

HBW/Hand bulit wheel

From prototype to production, every wheel gets assembled by hand. There is no substitute for the experience and meticulous attention to detail that a human being brings to the craft of wheel building.
