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.
New in 2015, two evolved versions of the 3D System:
- The Gallium Pro's 3D System is now press-fitted, in order to be easier to install and lighter as well.
- The Nitrogen introduces the AERO 3D, which helps reduce drag to a minimum. It is also press-fitted.
|The numbers tell the story|
|Structure and diameter||Increased rigidity under load|
|3D structural spacer outside diameter: 52mm
Comparison with traditional spacers:
Carbon fibre: +58%
|Compared to a standard 10mm spacer, a 3D structural spacer increases rigidity by 5%.
A 20mm 3D spacer increases rigidity by 11%.
Using the 3D system with no spacer places the bearing directly under the stem:
flexing is virtually eliminated
