Technology we use on gravel frame production
Use the newest one-piece latex 3D mandrel and molding technology.
Such technology helps to optimize the orthodromic and strength of carbon fiber, and avoid wrinkle inside (wrinkle is a key factor that may cause crack)
Even using the same material, the strength is improved 30%.
One-piece 3D latex mandrel helps to make smooth inner side of frame.
To achieve same strength, tradition method requires thickness 1mm-1.2mm, while such new technology only requires 0.5mm-0.8mm thickness. Thus, we are able to make the frame about 15% lighter, given strength unchanged
