The idea started with a question: what is truly possible when development, materials and manufacturing come together in a new context? That question became the starting point for a project in which we are working step by step to develop and produce advanced carbon fibre frames in Sweden - from the drawing board to the start line.
In the first chapter, we introduced the vision behind the project and presented the collaboration with Aston Harald Composite - a partner whose expertise in advanced composite manufacturing makes this project possible.
In chapter two, we took a deeper look at the material choice and why we chose to work with TeXtreme® carbon fiber - a material used in some of the world’s most demanding applications, where weight, strength and precision are critical.
Together, these parts form the foundation of the project: the vision, the partnerships and the material.
To take the next step, we needed to define where it all begins. This is where chapter 3 of The Swedish Bike Project starts - the design process.
It became clear early on that the project’s first bike would be developed within a discipline where aerodynamics and efficiency are critical. The choice fell on triathlon.
Here, performance is decided in the margins - small changes in form, position and integration will have a measurable impact over long distances. It is also a discipline where the bike’s design does not just support performance, but defines it.
Having the opportunity to collaborate with one of Sweden’s leading elite triathletes added another dimension to the project - but more on that in a later chapter.
The initial sketches focused on finding the balance between stability and aerodynamics - between a frame that feels composed at high speed and a silhouette that cuts through the wind. Geometry and ergonomics determine how efficiently the rider can maintain an aerodynamic position over long distances, while the bike must remain stable and predictable at speed.
From these early sketches, ideas around integration also began to take shape. The goal was a frame where components, storage and aerodynamics work as one cohesive system - rather than as separate elements.
As the direction became clearer, the work moved into the digital domain. Using CAD, the frame was built in three dimensions, allowing proportions, lines and surfaces to be evaluated both as a whole and in detail. At this stage, functions were also integrated into the design, while the form was gradually refined and the bike began to take on its distinct identity.
Once the digital model had reached a sufficient level of maturity, the next step followed. To verify fit, ergonomics and aerodynamics, the design was brought into the physical world through 3D printing. On a large FDM printer, the frame was built layer by layer, with complex geometries supported by temporary structures during the process.
After assembly and surface finishing, the 3D-printed prototype takes on a more complete, refined form.
Still only a physical interpretation of the idea - but real enough to give a clear sense of the bike to come.
From the first lines on the drawing board to a form that can now be held in hand. A step in exploring what is possible when development, materials and manufacturing come together here in Sweden.
We call it - Allebike ASTON.
And the work continues.
