The past, present and future of road racing innovation
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.
Look around the pro peloton today, and it’s hard to find a bike that hasn’t followed in the footsteps of the original TCR
But that was just the start for TCR. Since that first-generation aluminium model, this bike has constantly evolved. Giant engineers and athletes have worked together creating new innovations to keep it ahead of the pack. Over the past 23 years, we have made multiple advances in material engineering and introduced new design concepts to continually make it lighter, stiffer and more compliant. And every new generation proved itself on the road, carrying some of cycling’s top pro racers to wins at the highest level including multiple stage wins at the Tour de France, two Giro d’Italia overall victories (2009, 2017) and dozens of major classics, WorldTour races and national championships.
That brings us to the 9th generation TCR
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.
Evolution of the TCR
Since it debuted as a controversial aluminium-framed race bike with compact geometry and a radical new look compared to all other race bikes in 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.

Key Performance Factors
Ultimately the new TCR Advanced SL had one critical goal that would determine its success: it had to produce measurable performance gains for the pros who race it day in and day out. Our team of engineers, product designers, aerodynamic experts and pro athletes worked together to research, develop and test new ways to achieve the near-impossible task of creating a TCR that was more efficient and aerodynamic while retaining the precise handling and control of the bike that came before it.
A high stiffness-to-weight ratio is a hallmark of the TCR. To retain this critical advantage, the 2021 TCR Advanced SL features new cutting-edge composite materials, reengineered tubing shapes and advanced robotic layup techniques. The result is a livelier ride quality, explosive acceleration and improved climbing efficiency with up to 26.3 percent greater frame/fork stiffness than key competitor bikes*. *2019 Trek Emonda SLR Disc.
The new TCR takes a major leap forward in its aero performance. This is where its most quantifiable gains, compared to the previous generation, can be found. Every tube shape was analysed, engineered and tested to create an overall structure with significantly lower drag at a wider range of yaw angles. The result is a TCR that’s faster than ever, especially in sprints and solo efforts.
From updated disc-brake integration to all-new composite WheelSystems that offer greater stability in crosswinds to user-friendly tubeless tyre setups, the new TCR delivers greater control in a wide variety of road riding conditions. A new composite fork boasts 35 percent greater torsional stiffness over key competitor bikes* for unrivalled steering precision and added frame/fork clearance allows higher volume tyres up to 32mm** for a smoother, faster ride on all types of road surfaces. *2019 Cervelo R5 Disc **dependent on brand
Stiffness-to weight comparison
Giants testing determined how much the complete frameset flexed torsionally under load. Each frame was locked at the rear dropouts with lateral force applied to the fork. More frame stiffness means better cornering and response to rider input on the road. The TCR Advanced SL Disc provides up to 26.3 percent greater transmission stiffness than some of its competitors.

|Total weight saving
Compared to the outgoing TCR Advanced SL Disc frameset, the all-new version saves 140 grams through its state-of-the-art manufacturing techniques and advanced materials usage. Furthermore, comparing its weight against key competitors, the new TCR Advanced SL Disc is lighter than the current Specialized S-Works Tarmac Disc (105 grams) and the Cervelo R5 Disc (322 grams). The significantly less stiff and less aerodynamic Trek Emonda SLR Disc is slightly lighter (17 grams).
