From the World Tour to the Bike Clinic.

A career built on the millimetre — from the Tour de France to clinical biomechanics.

THE PELOTON

Before the toolbox, the bike: racing at elite level taught me effort from the inside — what a position costs, and what it gives back. A serious accident at eighteen left me with a body that no longer sat straight on a bike.

Years passed. Many fits. No answer.

THE WORLD TOUR

At the UCI World Tour level — FDJ — I became the youngest mechanic in Tour de France history.

The peloton's workshop has one unit of measurement: the millimetre, under pressure, with no second chance.

THE METHOD

After years of fittings that never held, I travelled to Australia to be fitted by Neill Stanbury. He fixed me. 30'000km for few millimetres. 


In 2026 I crossed the world again — this time to train under him. I am now the only practitioner worldwide he has certified.

Clinical biomechanics: the body assessed before the bicycle is touched.

COQUILLADE PROVENCE

I joined the Cycling Center at Coquillade Provence, and came to direct it. An international clientele, a team to lead, a Relais & Châteaux house to serve.

Today, House Ambassador, I welcome you at La Bike Clinic.
