The heart of reason
Because every work of art is born from a concrete thought
UFS™ TECHNOLOGY
Unishell Frame is a load-bearing frame model that is registered and patented by SWI and is based on the integrity (front and rear) of the frame as a monocoque, i.e. conceived as a single mould to increase the strength and the overall structural rigidity of both the transversal and longitudinal torsion.
UD Core with 3K skin
The key to increasing the structural performance of the frame is the rational use of the many features of the carbon fibre in the different parts of the frame. All SWI frames are made exclusively with UD (uni-directional) fibres. Unlike common carbon fibre products that are made of interwoven fibres (with the classic cross-ply appearance), UD carbon is literally a continuous piece of carbon with filaments placed in a single direction. Our frames are constructed by overlapping 14 to 19 very thin layers of UD carbon laminate. The outer layer of 3K carbon arranged in a herringbone pattern gives the SWI a unique and unmistakable aesthetic.
TPT™ THIN PLY TECHNOLOGY
TPT stands for Thin Ply Technology™, i.e. the technology of thin plies. In other words and more simply, the thinner the laminate plies (final thickness being equal) the better the mechanical properties. Therefore, with the same mechanical properties, we have less thickness and lighter weight.
BUILT ON YOUR PERFORMANCE
What makes every Swi bicycle truly unique, our most precious business card, what makes us different from all the others. We will sew the frame to your characteristics: thanks to the processing of the carbon layers you can choose a more or less rigid, more reactive or more comfortable bike according to your needs and the type of cyclist you are. Because every Swi bike is unique. Just like you.
GEOMETRY
The weight of the SWI frame varies between 650 and 750 grams, in relation to the sizes. It is designed for the sole use of the electronic derailleurs and disc brakes with internal cable routing. The weight of the SWI Di2 Disc bicycle in the medium size is 6.8 kg (pedals included). The Swi frame is produced in 7 sizes from size 48 to 60. The frame construction time is around 60 days.
