3D System

The 3D System* (*Patent pending) is an Argon 18 exclusive, a simple but clever mechanical solution for perfect adjustment of handlebar height for every rider. The device is a structural extension of the headtube. It keeps the headset bearings close to the stem, even when the cyclist needs a more upright position. Three positions are available: 0mm, 10mm and 20mm.

The 3D System allows for 3 effective headtube heights for every frame size, so that riders benefit from:

1. A position perfectly adapted to the individual’s physique and riding preferences
2. More precise handling and an uncompromized racing frame
3. Better front end stiffness

Increased front end stiffness: A larger diameter means more rigidity

• The head and steertubes, which have grown from 1’’ to 1’’1/8 and now to 1’’1/4, have been enlarged for a single reason: to increase rigidity for quicker acceleration.
• This change in bike design, however, hasn’t led to any modification in diameter or shape of the spacers customarily
  used to adjust stem/handlebar height.
• Therefore, much of the intended boost in stiffness is lost to overly flexible conventional spacers on an unsupported
  steertube end section.
