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

Downtube Storage Design (with small bag optional)

Downtube storage space is a savior for sundries. Keys? Energy gel? Spare inner tube? Or portable tools? LCG071-PRO wants to give them a "home". The storage space is a solution for high-intensity outdoor long-distance riding. The goal is to solve the problem of placing some sundries that are necessary for outdoor riding. We took advantage of the large space of the down tube and designed a storage system that can accommodate 2 pcs of 200 ml storage bags. The specific lid is also designed with standard hole for bottle cage. So, in addition to storage space, bottle cage can also be installed same as common bikes.

Two Versions Of Fork Optional

Two 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.

Special Design For the Top Tube

25mm offset seat post, providing better comfort for long distance cycling.

Top tube shaved off at the position near seat tube, which helps to reduce vibration and result in better comfort.

3D Latex Mandrel Technology Used In Our Carbon Frame Production


real photo of our cross-section	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%.
LightCarbon Frames Produced With 3D Latex Mandrel vs Other Frames

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.
