Gravel Frameset internal cable routing

A – Rear derailleur cable routing

B – Rear disc brake cable routing

C – Front Derailleur cable routing

D – Front disc brake cable routing

All cables were integrated though handlebar stem through head-tube, integrated design to make complete bike clean and aerodynamic.

25mm Offset Special Design Top Tube

25mm offset  seat post, providing better comfort ability for long distance cycling. Top tube shaved off at the position near seat tube, which helps to reduce vibration and result in better comfort ability.

3D latex mandrel Technology 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%.

Tradition method and 3D latex mandrel produce Products Compare

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
The above picture shows frame made with tradition technology and new 3D latex technology, for tradition method which is with many wrinkle and bubble inside. For 3D latex mandrel which is smooth inside, no wrinkle or bubble.
