We have 3 types of ultralight carbon mountain bike rims to release, widths in 27mm, 30mm and 34mm.The profile drawings are as below:
29" 27mm rim model is NXT29UL27, weight is only 280g.
29" 30mm rim model is NXT29UL30, weight is 310g.
29" 34mm rim model is NXT29UL34, weight is 350g.
27mm and 34mm rims are symmetric, 30mm rim is asymmetric.
We use 30% T1000 carbon fiber + 70% T700 carbon fiber materials to manufacture these ultralight mtb rims, specially design the layer-up system.
T1000 is a very expensive materials, it's usually used in military project. The stiffness/rigidity is much higher than T700 or T800, and very light. While, relatively the tenacity is not as good as T700.
So we choose T700 + T1000 carbon fiber to manufacture the ultralight rims. Plus, the spoke holes wall is designed with single point reinforced, good to decrease weight while keeping the strength enough.
