The Technology

Performance is personal.
A ride feel like no other.

Three engineering principles separate every SWI from every other carbon frame on the road.

01

Unishell Monocoque

One continuous carbon shell. Zero joints, zero bonding.

02

Precision Geometry

Tolerances held within 0.1mm — every frame, every time.

03

TPT™ Carbon Textile

Swiss-engineered composite. 14 layers per millimetre.

From Unishell construction to autoclave pressure — the full technical story.

The Founder

From gold jewellery to carbon fibre.

SWI was founded by Stefano Cenere, after a career shaping intricate pieces of luxury gold jewellery.

A lifelong cyclist, he saw that the moulding techniques behind fine hollow gold links were not far from those behind a carbon frame and set out to build one with a jeweller's obsession for detail.

Development

8 years of relentless pursuit

The story began in 2014. Over eight years and more than fifty prototypes, Stefano developed a unique process and set of moulds for forming an uninterrupted monocoque carbon shell.

He worked with specialists in modelling and finite element analysis, and tested with some of Italy's most demanding professionals — among them the Olympic and two-time world champion Paolo Bettini, and the classics legend Luca Paolini — until the frame was ready.
