Two Fork Versions Optional 

Two Gravel Fork Versions Optional

 The default carbon gravel fork is equipped with 3 rivets on each side of the fork leg. Considering that some riders do not intend to put small luggage or bottles on the fork legs (which would interfere with handling), this gravel fork has another option, namely there are no rivet holes on each side. If you prefer a fork without riveted holes, please let us know when placing your order.

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. 


Technology we use on gravel frame production

gravel bike frame material

real photo of 3D latex mandrel
 3D latex mandrel applied on frame


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
3D latex mandrel produce Products 3D latex mandrel produce Products


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.
