GLOSSARY :
CHROMOLY :
A superior quality steel alloy from the SAE 41xx serie, used to manufacture forks. Includes Chromium and Molybdenum. Also called Crmo or Chromo.
SEAMLESS :
Superio quality tubing obtained by direct extrusion, without any weld-joint process. Stronger than other laminated / roller / welded tubes.
HEAT-TREATMENT :
Heat treatment is an industrial process involving the multiple use of heating and chilling, at high extreme temperatures, to harden a material, or change some of its mechanical properties.
ELECTRO-DEPOSIT :
Surface treatment process used to coat a metal product. The part is placed in a special bath with pigments and an electric field. Used to protect the material (steel, in this exemple) against corrosion (inside and outside the tubes). Also called "ED" like in ED Black.
INVESTMENT CAST :
Manufacturing process for the fork dropouts. A cast is used to produce a single homogenous block, without any weld, and so with less stress. This gives a stronger dropout area, useful in case of peg riding.
BUTTED / MULTI-BUTTED :
A tubing with multiple (inner) thicknesses. The tube is thicker around the stress areas (angles, welding spots) and so stronger / more durable. This allow the fork to have a better strength / weight ratio.
TAPERED :
Variable tubing (outer) diameter, usually in a conical shape. This shape is used to get a better strength around stress areas, like giving wider welding surface. Similar to the butted tubing, but on the outside of the part.
CNC MACHINING :
Usually used to manufacture fork steerers, this machining process is controlled by a numerical computer, offering more precision, but also a better finish compare to a traditional machining process.
