The brand started with a local team, developing and selling top carbon frames. First in South Africa and after around the world, year over year, the company grew up and the team was changing from local to multicultural and wide geographic group, creating the need to build a new headquarter and production facilities. The decision was established into the most aggressive market in the world: Europe. This big jump cost almost five millions dollars and gave the company a new dimension and the capacity to answer the market with an impressive range of bikes.
On every Road, MTB and TT bike, we care every detail to offer the rider an amazing performance. SwiftCarbon bikes are developed with high-quality carbon by developing innovation-driven competencies based on the principles of value creation and social and environmental responsibility, in international markets, providing adapted products to customers' requirements.
SwiftCarbon is a new kind of bicycle company that was born from a genuine love and passion for cycling and to develop the best bikes in the world. Swift implies "high speed", "fast" and "velocity".There are many factors to define this. We believe that the professional factor holds the greatest value in the frame design equation.
What sets SwiftCarbon apart is how the bicycles should ride. For us, the beauty of a bike is not just what it seems, it's how it feels too. Tuning the best quality of steering and handling on our bikes means that sometimes we have to let go of the latest trends by creating our unique designs. We strive to develop bikes for true riders, always keeping the passion for cycling for all conditions and with a broad vision, because a bike you like to ride is the one you like to pedal frequently and quickly.
De-mystifying carbon fibre
The material we call carbon fibre is actually a composite of different types of carbon filaments held together by a resin. Just as there are different alloys of aluminium and steel, so there are numerous types of carbon fibre filaments. All SwiftCarbon bikes use a combination of T700, 800 and 1000 filaments, to deliver the superior ride quality of every bike. These different kinds of filament can be combined in different ways. Uni-directional (UD) carbon fibre has all the strands running the same way - it's very strong in one direction, less so in others. Woven carbon has interwoven strands at 90 degrees to one another, making it strong in both directions. Which is used and where depends on the desired characteristics of the frame. Keeping a tight range means that we can invest the time needed to get each frame as good as it can be. For us, the quality of the product is paramount - get that right, and people will buy it.
The development of every SwiftCarbon product starts with a vision of what the product has to do. Our unique design process spans continents. Having identified the desired attributes, sketches and concepts are swapped between our designer in Europe and our engineer in South Africa. Bicycle design is a balancing act, juggling often conflicting requirements. A frame needs to handle accurately and be stiff under power, but also deliver a comfortable ride. lt needs to be strong, yet light. And it must look good, too. Drawings become plans and computer models, which become prototypes to be tested in real action and in laboratory.
Finite Element Modelling
One of the unique benefits at different types of fibre can be placed in varying orientations within a frame, putting strength exactly where it's needed. Using Finite Element Modelling (FEM) to visualise the loads on frames on computer, we can experiment with different materials, lay-ups and structures without having to build numerous physical prototypes.
With FEM, we can simulate the loads from riding and see exactly how those loads will affect a frame design. This step is essentially Finite Element Analysis (FEA), which not long ago was state of the art. FEM goes further, though, allowing us to add, remove or change material and refine the design virtually, testing as we go along. Once a frame design is performing as we want it in FEM, we know it's worth making a physical prototype for real-world testing.
EPS Moulding System
Making a carbon fibre frame involves compressing layers of carbon weave and epoxy resin into a mould to get the desired shape. Traditionally, inflatable bladders are used inside the frame to force the material into the mould, but because the shape of a bladder can't be finely controlled there can sometimes be wrinkles or inconsistent thickness in the finished frame. To avoid this, we use expanded polystyrene - essentially the same stuff that cycling helmets are made from.
We can make EPS formers to the exact shape we want before laminating carbon fibre around them and placing the whole lot in a mould. When heated, the individual beads in the EPS formers swell. Out in the open they'd reach 40 times their original size, but constrained by the mould they exert pressure on the inside of the carbon fibre, pushing it into exactly the desired shape with consistent thickness and no wrinkles.
But carbon fibre isn't just carbon fibre: woven carbon filaments by themselves aren't very useful. What turns carbon fibre from loopy sheets to stiff, resilient frames is epoxy resin. The resin binds the layers of carbon fibre together to form a composite structure. We use Carbon Nano Tech (CNT) reinforcement in the resin for our frames. These molecular-level cylindrical structures can strengthen a product significantly, but success relies on careful manufacturing.
These molecular-level cylindrical structures can strengthen a product significantly, but success relies on careful manufacturing. lt's easy for the tubes to clump together, leading to inconsistencies. Our construction technology gives us precise control of the distribution of resin in the carbon layers, ensuring that the nanotubes can do their job - giving a stiffer and more durable frame.
