Argon 18, official supplier to Team SpiderTech, presents the popular Krypton for 2012, a proven stellar performer in any setting.
Think of the world’s most beautiful and challenging roads, the places of cycling legend; that’s where the Krypton belongs. This bike has it all: low weight, comfort, efficiency, it’s all there, optimally balanced. All that’s missing is you.
AFS Road Geometry
Whether you prefer a low, aggressive stance or a more relaxed position, AFS geometry allows enough leeway in its range of adjustment to accommodate all types of riders. Every dimension is calculated to facilitate optimal positioning for unequalled comfort, even on those day-long rides.
At a glance, a bike’s geometry is not something very noticeable or obvious, but defining a frame’s geometry is a subtle but critical element in designing a truly outstanding bicycle. Argon 18’s AFS geometry means that every frame size has been given balanced, logical dimensions, making each frame ergonomically sound while ensuring that the bike has the desired characteristics on the road: accurate steering, agility, quick response and predictable handling.
- An ideal position for riders of all sizes
- A responsive, nimble bike regardless of frame size
Optimally balanced proportions
For every frame size, the following dimensions are defined to achieve an optimal balance:
- Seat tube angle
- Front top tube and rear top tube lengths
- Head tube angle and length
- Overall wheelbase, divided into two sections: chainstays and front center
The Kryptoncomes 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:
- Basic head tube length, no 3D spacer
- Basic head tube length + 15mm
- 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.
An Integrated Design
The Krypton was conceived as an integrated unit, built in a proprietary mold. It includes the following elements:
- A monocoque carbon frame, optimized according to HDS principles.
- The Kr 36 carbon fork, also molded as a single piece, with excellent vibration dissipation, contributing to the Krypton’s outstanding comfort
- The ASP 1500 seat post. Made of carbon fiber, it’s damping qualities complement the fork’s, for enhanced comfort.
HDS: Horizontal Dual System
The tubes that make up a frame all have a different role to play in the bike’s performance. The required rigidity must be correctly apportioned in the most highly-stressed parts, primarily along the lower areas, while a measure of absorbency is needed in the upper region to ensure comfort, while reducing weight throughout.
Argon 18 maximized stiffness in the frame with massive, asymmetrical chainstays as well as an oversized bottom bracket shell and head tube.
The frame’s upper areas feature smaller, thinner tubes that absorb and dissipate vibration from the road.
Whether in training or during a race, HDS construction lessens fatigue thanks to the enhanced comfort while the lateral rigidity maintains maximum efficiency, losing none of the athlete’s power in propelling the bike forward.
5650 HM Carbon Composite
5650 HM, consisting of high-modulus, is one of the main reasons for the Krypton’s exceptional performance. An elaborate fiber layup scheme varies the orientation and number of plies in response to the stresses occurring in each part of the frame and thus achieves excellent strength-to-weight ratios. Compared to the Radon, these strength-to-weight ratios are higher as measured in these areas:
- 20% in the rear triangle
- 9% in the bottom bracket
This substantial lateral rigidity means the Krypton tracks true and remains composed even at very high speeds.
Efficiency from a well-considered design makes the Krypton a lively, punchy performer that always remains comfortable.
