UD X Weave :
-Overlap the carbon fiber cloth in an X shape
-These carefully woven layers of carbon fibers are designed to overlap evenly over the spokes holes, which makes the tensile strength of the spoke holes increase by 6% and hold up to 380kgf. The appearance of UD X Weave make the rim stronger and safer. Based on the technology of YUANAN, this look does not add weight to the wheels.
-50mm depth,29mm outer width.The most classic, popular and practical wheels.The same U-shaped aerodynamic performance, with 19.5mm internal widths, providing more precise choices
-A1 sculptural brake surface

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.
