MAKING



The frame quality depends on the frame-maker's skills and dexterity. Blowtorches are highly skilled brazers best tools.
Hand-made alignment tables allow the positioning, the assembling and the control of frames.

 

 


     
The craftsman's traditional expertise is combined with modern means.
Computer aided conception methods offer preciseness.
       
   
RACKS
   
Racks receive the same attention as frames. Tubes are bent on a special machine of our conception and tube angles are then controlled on alignment table.
         
POWDER-COATING
   

ADVANTAGES:
The powder perfectly sticks to the frame.
Very good resistance to shocks.
Long-lasting.
No pollution (no solvent).


DISADVANTAGES:

The surface is less even than with liquid coating. There may be some small imperfections (powder can not be controlled as it melts during firing).
To guarantee a good result, two processes are first carried out:
- scouring and anti-corrosion protection baths,
- sand blasting, to ensure perfect paint adhesion, consists in 'throwing up' small corundum grains at a very high speed onto the frame to make it clean.
Made with powder colors, not with liquid colors.
We use a special spray gun which allows the powder to be attracted onto the frame as if it were a magnet.
The frame is perfectly covered thanks to this method.
The frame is then put into a kiln to fire the powder.
   
The different tubes are firstly brazed with just a little spot on the frame for made-to-measure models, or on a template for standard models. The whole rack is then taken apart, full soldered, surfaced on the alignment table and fixed again on the frame or the template for a last check before it is powdered.
   
HAND MADE WHEELS
Wheels are certainly the most suffering elements in a bike. All of our wheels are hand-made.
Spokes are progressively tightened to ensure a more even tension. As for spoke nuts, they are fixed with a small drop of nipple stick.
Wheels are centered and then hand-pressured, 'tortured' once, twice, three or four times if necessary, until they no longer loose their shape under the constraints we place upon them.
           
BAGS
 
The raw materials we use are strictly selected, nothing is left to chance. The resistance of leather, its softness, its lengthening, its thickness are strictly controlled. Parts are assembled by experienced hands according to the laws of traditional saddlery.
