The Trek 5500: A Revolutionary Bicycle in Cycling History
The Trek 5500, introduced in 1999, was a groundbreaking bicycle that marked a significant shift in the world of cycling. This monocoque carbon fiber bike not only won the Tour de France but also symbolized the end of an era for steel and aluminum bikes. The story of the Trek 5500 is a fascinating one, filled with innovation, controversy, and the evolution of cycling technology.
The Redemption Tour and the Rise of Carbon Fiber
The 1999 Tour de France, dubbed the 'Redemption Tour,' was a pivotal moment in cycling history. It followed the Festina doping scandal of 1998, which cast a shadow over the sport. However, the irony of the situation is that it was Lance Armstrong, who would later be stripped of his titles for doping, who won the race. This victory marked a turning point, as it signaled the end of the dominance of steel and aluminum bikes. From that moment on, carbon fiber became the new standard in cycling.
The Trek 5500 played a crucial role in this transition. Its carbon fiber frame, constructed using a monocoque system, was a significant advancement in bicycle design. This innovative construction method, where loads are supported by the outer surface, resembled the structural integrity of an egg shell. Trek's earlier 2500 model, introduced in 1987, had experimented with bonded carbon fiber main tubes into aluminum lugs using an aerospace bonding method. Building upon this foundation, Trek developed the OCLV (Optimum Compaction Low Void) method in 1989, which was further refined in the 1992 release of the 5500 OCLV.
Technical Innovations and Components
The Trek 5500 featured a bonded carbon and aluminum OCLV fork with a 1-inch steerer tube, which was a departure from the quill stem used in earlier models. This change reflected the evolving trends in bicycle design. In the 2000s, the 5500 transitioned to a 1 1/8-inch steerer and an ahead stem, further aligning with the industry's shift towards modern standards. The bike's groupset, provided by Shimano Dura Ace 7700, included a 9-speed cassette and Shimano Total Integration (STI) gear and brake levers. This setup broke Campagnolo's long-standing dominance in the Tour de France and introduced a new era of shifting technology.
The Rolf Vector Pro wheels, another notable component, utilized a patented system of paired spokes to reduce the left/right pull caused by conventional spoking arrangements. This design allowed for a more efficient and smooth ride, with 14 spokes in the front and 16 in the rear. The wheels were specifically designed for tubular tires, with a 20 or 21mm width, which expanded to 23mm for mountainous stages, ensuring better handling on descents.
The Hutchinson Pro Tour Tubular Tyres and Saddle
The Hutchinson Pro Tour tubular tires were a unique feature, with rumors suggesting they were aged in a wine cellar to enhance their suppleness. This practice was likely a strategic move to deter competitors. The Trek 5500 also featured a Selle San Marco Concor Light saddle, a popular choice among professionals at the time. Armstrong's preference for the classic, curved shape of this saddle over the standard team issue further highlights its significance.
The End of an Era
The Trek 5500's victory in the 1999 Tour de France was a pivotal moment that solidified the dominance of carbon fiber bikes. Despite the use of classic drop handlebars, a 1-inch quill stem, and rim brakes, the bike's carbon fiber frame and innovative components showcased the potential of this material. Over time, these traditional features would gradually disappear, leading to the evolution of modern bicycles.
In conclusion, the Trek 5500's success in the 1999 Tour de France not only marked a redemption for cycling but also accelerated the adoption of carbon fiber technology. Its impact on the sport cannot be overstated, as it paved the way for the high-performance bicycles we see on the roads today. The Trek 5500's legacy continues to inspire and influence the cycling industry, reminding us of the power of innovation and the relentless pursuit of excellence.
