Swift Carbon


We pay huge attention to every part of the ride, balancing often-contradictory requirements. For example, to make stiff frame, more material is required, either to make higher-volume tube sections or to make tube walls thicker. More material means more weight, so stiffness and weight are always a trade-off. It’s possible to use stronger materials, which let you use less material for the larger tubes, but that introduces the additional axis of cost.

It’s a similar scenario when it comes to aero features. A tube with a deep aero cross-section inevitably uses more material than a round tube. It’s a question of balancing the benefits of reducing drag against the weight penalty. Aero tubes are also stiffer along the long axis of their cross-section, which often seriously compromises frame comfort and ride quality. We spend a great deal of time testing and assessing all these axes of performance to achieve the ideal balance.

We pay particular attention to the ride quality, deliberately setting out to achieve a ride feel comparable to the very finest steel bikes of the mid 1980s, when steel was the dominant frame material. The geometry, feel and characteristics of 853 and 753 Reynolds frames that Mark rode as a professional left a lasting impression on him.
