Downtube Storage Design (with small bag optional)


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.

T47 BB For Shimano 24/Sram DUB 29/30 Crank


T47 BB For Shimano 24/Sram DUB 29/30 Crank

More and more new carbon frames are designed with T47 bottom bracket, including those big brand carbon bike frames. There are mainly two popular types of BB for T47: Inner diamater 24mm for Shimano standard crank, and Inner diameter 29mm/30mm for Sram standard crank.

3D Latex Mandrel Technology Used In Our Carbon Frame Production

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
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.
