The Lance Armstrong-era Trek 5500: A Revolutionary Carbon Fibre Bike
The Trek 5500, Lance Armstrong's 1999 Tour de France-winning machine, was a game-changer in the cycling world. It marked the beginning of a new era where carbon fibre became the dominant material in professional racing, replacing the traditional steel and aluminium bikes. This bike was not just a machine; it was a symbol of the shift in cycling technology and a testament to the power of innovation.
What makes the Trek 5500 particularly fascinating is its use of a monocoque carbon fibre frame. This design, where the entire frame is made from a single piece of carbon fibre, is inspired by the structure of an egg shell. It's a bold move that significantly reduces weight and increases stiffness, making the bike more responsive and efficient. This innovation was a breakthrough, and it's hard to imagine the Tour de France without carbon fibre bikes today.
The bike's fork, too, was a marvel. It used a bonded carbon and aluminium OCLV (Optimum Compaction Low Void) construction, which was a significant improvement over the bonded tube and lug method. This design not only reduced weight but also improved the bike's overall performance. The Trek 5500's fork was a prime example of how carbon fibre could be used to create a lighter, stiffer, and more responsive bike.
The Shimano Dura Ace groupset on the Trek 5500 was another significant innovation. It was the first time a rider using Shimano won the Tour de France, breaking the long-standing dominance of Campagnolo. The 7700 version of Dura Ace, with its 9-speed cassette and Shimano Total Integration (STI) gear and brake levers, was a game-changer. It was the last time downtube shifters were offered as an option for the top-level groupset, making it a historic moment in cycling.
The Rolf Vector Pro wheels were another standout feature. They used a patented system of paired spokes to reduce the left/right pull introduced by a conventional spoking arrangement. This allowed for a lighter and more efficient wheel, which was crucial for climbing. The Hutchinson Pro Tour tubular tyres, kept in a wine cellar to artificially age them, were another interesting feature. These tyres were designed for tubular tyres, with a 20 or 21mm tyre width, expanding to 23mm for mountainous stages.
The Selle San Marco Concor Light saddle, with its titanium rails, was a staple of the professional peloton at the time. Armstrong's preference for the classic, curved shape of the Concor Light over the standard team issue saddle is a testament to its comfort and performance. Selle San Marco still makes the saddle, with a Concor 50th Eroica version for those wishing to restore their own.
In my opinion, the Trek 5500 was a turning point in cycling. It marked the end of the era of metal bikes and the beginning of a new, carbon fibre-dominated landscape. It was a bike that not only won the Tour de France but also changed the way we think about cycling technology. It's a bike that continues to inspire and influence modern cycling, and it's a testament to the power of innovation and the human spirit.
What many people don't realize is that the Trek 5500 was not just a bike; it was a symbol of the shift in cycling technology and a testament to the power of innovation. It was a bike that not only won the Tour de France but also changed the way we think about cycling technology. It's a bike that continues to inspire and influence modern cycling, and it's a testament to the human spirit.
