When the first TCR arrived in the pro peloton more than 20 years ago, it was surrounded by controversy. It looked unlike anything else in professional road racing at the time, and rival teams were left wondering if the Giant-sponsored Team ONCE had an unfair advantage. Officials from cycling’s world governing body were called upon to determine if the bike was legal.
The questions and controversy had to do with frame geometry. The name of the bike clearly spelled out its main innovation: Total Compact Road. The brainchild of British bike designer Mike Burrows—who had already introduced some game-changing race bikes including Chris Boardman’s gold medal pursuit bike at the 1992 Olympics—the first TCR frame was a clear departure from the standard road bike design that had prevailed for decades. Its radical geometry was marked by a “compact” frameset featuring a top tube that sloped downward from the head tube to the seat tube.
Compact Road was inspired by mountain bikes, which were sill relatively new in the early 1990s. Burrows worked with Giant to create the Compact Road frames, which offered several obvious advantages. The sloping toptube created a smaller main triangle, which was both lighter and stiffer than standard frames with horizontal toptubes. The rear triangle was also smaller, which in addition to saving more weight also improved power transfer and efficiency.
The first TCR also ushered in a new era in production for high-performance road bikes. Its Compact Road geometry made it far easier to fine-tune the fit and position of the rider by simply adjusting seatpost and stem lengths.
Those early ONCE team bikes were instantly recognizable by their longer seatposts, which gave them a profile that more resembled mountain bikes. The other advantage was that longer seatposts could be shaped for better aerodynamics or crafted from carbon fiber to add compliance and smooth out the bike’s ride quality.
Ultimately, UCI officials decided the TCR was legal. Team ONCE riders including Laurent Jalabert went on to win dozens of races on it, including grand tour stages and major one-day races. The early TCR was unique in its ability to excel in mountain stages and time trials. With its aerodynamic advantages, it was especially effective against the clock—Jalabert won several stage race time trials on it, and ONCE became a favourite at every team time trial it entered.
Continuing a tradition that began more than 20 years ago, the flagship model of the new range, the TCR Advanced SL, is the result of a team effort involving Giant engineers and product developers, leading aerodynamics experts, and some of today’s top professional racers including Olympic champion Greg Van Avermaet along with other CCC Team riders and technical staff.
The project began with a nearly impossible goal: Make it even more efficient. That’s the story of the new TCR Advanced SL—squeezing more speed out of every pedal stroke. To accomplish that, our team analyzed every aspect of the bike, from raw materials to all-new manufacturing processes. Even the paint was created to minimize weight.
In the end, the major breakthrough with this TCR is that it is significantly more aerodynamic than the previous generation while retaining its best-in- class stiffness-to-weight ratio. Every tube shape has been modified to reduce drag without adding a single gram or compromising the qualities that have made TCR a leading pro-level race bike for two decades.
Like the original TCR, it took a complete re-think to accomplish this goal. The following pages present the details on the engineering, aerodynamic development and technical details that make this the fastest TCR ever.
Since it debuted as a controversial aluminum-framed race bike with compact geometry and a radical new look compared to all other race bikes Sn the late 1990s, the TCR has continually pushed the limits of performance with every new generation. It has been a staple in the pro peloton since 1998, earning wins at major races around the world for more than two decades.
