.The 27.5er ultralight MTB rim, we created a race-level ultralight rim for cycle cross riders specially.On the premise of not losing strength, we can reduce the weight of the rim as much as possible, and also reinforce the position of spoke holes. The inner wall of the wheel is smooth ,it doesn't affect the tension of the spokes

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.
