SWI is driven by a mission to produce the most advanced bespoke carbon bicycle frames. The only brand hand-building unishell carbon monocoque frames customised to match the rider’s weight and power output, every SWI frameset is built upon 3 pillars: engineering mastery, craftsmanship & extreme attention to detail. Originating in Ticino, Switzerland , SWI now designs and handbuilds it’s own framesets in Bassano Del Grappa, at the heart of the Veneto region in Italy.

Unlike traditional custom frame builders who glue tubes and lugs together, or the mass market modular monocoques, SWI utilises a unique patented, unishell monocoque construction process which uses a single mould and produces a frame as a single uninterrupted carbon shell. This results in a lighter, stiffer, stronger and more precisely aligned frame than is possible with bonding.

NTPT™ Carbon Textile

TPTTM carbon textile is the DNA and power behind every SWI frame. An exceptionally dense carbon textile, it is used for carbon yacht racing sails, race yacht foils, the carbon chassis of F1 cars and Moto GP superbikes.
SWI is the only bicycle frame builder in the world utilizing TPTTM which in 1mm of thickness has 14 layers of carbon, compared to the standard carbon fiber used in frame building which only has 5 layers. This results in a frame that is exceptionally lightweight yet strong, safe and incredibly reactive due an unbeatable stiffness to weight ratio.
SWI is the only custom frame builder who tailors the carbon lay up of each frame to the individual rider based on the rider’s weight, power output and desired ride feel. We adjust the number of TPTTM carbon layers in key areas of the frame (e.g bottom bracket, head tube, chain stays) to deliver the rider’s desired stiffness to comfort ratio. This allows us to create lightweight and stiff frames that still provide supreme comfort on long rides.
