AFS GEOMETRY ROAD
The Argon 18 Krypton frameset offers unique fit options through the AFS geometry. This allows for drastically different fits on the same size frame. It doesn’t matter if you enjoy a low, aggressive riding position or need a more relaxed option, the AFS geometry means that every frame size is specifically designed to perform optimally. Not every frame performs the same way as the frame size gets smaller or larger. With the AFS geometry you get a frame designed exactly the way it should be across all sizes. What that means for the rider is better balance, stiffness, comfort and performance.
- An ideal position for riders of all sizes
- A responsive, nimble bike regardless of frame size
- Optimally balanced proportions
- Seat tube angle (B)
- Front top tube and rear top tube lengths (XXX)
- Head tube angle and length (C and H)
- Overall wheelbase, divided into two sections: chainstays and front center (XXX and YYY)
The Gallium comes equipped with the 3D Headtube system, an Argon 18 exclusive. Easy to install and adjust, 3D replaces conventional spacers with a structural mechanism that allows for handlebar height adjustment without compromising front-end stiffness.
Enhanced positioning versatility and superior front-end rigidity
The 3D system lets the user choose from three effective head tube lengths for a given frame size for positioning flexibility. These lengths are as follows:
1. Basic head tube length, no 3D spacer
2. Basic head tube length + 15mm
3. Basic head tube length + 25mm
A rider can fine-tune the bar height without piling up an excessive number of conventional spacers, leaving the frame’s rigidity intact. Thanks to 3D, a handlebar set at a 15mm height preserves 5% more stiffness over a similar conventional set-up, and this figure reaches 11% with a bar set at a 25mm height.Since the 3D Headtube system offers three effective head tube lengths, a rider can set the right position initially, but can later revise this position as fitness, taste or riding style evolve over time.
For every frame size, the following dimensions are defined to achieve an optimal balance:
