*Introduction*
French rider Paul Seixas made headlines during the opening stages of the 2026 Tour de France when he was spotted aboard a prototype Van Rysel frame that has not yet reached retail shelves. The sighting, captured by race photographers and quickly shared across cycling forums, offers a timely moment to examine how Decathlon’s in‑house brand has transformed its top‑level race machines over the past quarter‑century. From humble aluminum beginnings to today’s carbon‑fiber marvels, the trajectory mirrors broader shifts in professional cycling technology and retail strategy.

*Key Developments*
Decathlon launched Van Rysel in 2001 as a performance‑oriented line aimed at amateur racers seeking race‑grade specifications without the pro‑team price tag. Early models featured 6061‑series aluminum tubes, external cable routing, and modest groupset compatibility. By 2008, the brand introduced its first full‑carbon fork, signaling a commitment to weight reduction and vibration damping. The 2014 Van Rysel RCR series marked a turning point: monocoque carbon frames, internal cable routing, and integration with Shimano’s Dura‑Ace electronic shifting. Subsequent iterations added aerodynamic tube shapes, disc‑brake compatibility, and, most recently, a proprietary “FlexCore” lay‑up designed to balance stiffness with comfort. The 2026 prototype ridden by Seixas showcases a further refinement—nano‑enhanced carbon resin, a one‑piece cockpit, and a hidden battery port for emerging power‑meter systems, all while maintaining a sub‑800‑gram frame weight.

*Industry Analysis*
Decathlon’s evolution reflects three macro trends in the cycling sector. First, the democratization of high‑end materials: carbon fiber,
