New Lightest 28mm Outer Width Road Rim Series
Ⅰ.Introductions of New Super Ultra Light Road Series:
-1) 28mm outer width, U-shape designs, more aerodynamic and high stiffness.
-2) High modulus Toray T700 and T800 materials contained, reach lightest weight.
-3) Symmetric tubeless clincher structures, resist high impact strength of road/gravel cycling.
-4) 35/40/45/50/55/62mm profile heights are avaialble, suitable for different kinds of riding situations.
-5) Paintless/free paint carbon fiber surfaces, save the paint weights and enhance the fiber effect.
-6) Designed mainly for road cyclco-cross or gravel bike races, only disc brakes are available.
