Sport/Performance

The latest generation of our flagship road racing series has been winning the biggest races in the world for more than three decades. It's the ultimate all-rounder for the performance obsessed. The latest TCR Advanced SL Disc builds on its proven climbing capabilities, boasting its highest stiffness-to-weight ratio ever, and adds aero shaping in key sections of the frameset for added all-rounder performance. Additional updates include added frame and fork clearance to fit high-volume tires up to 32mm, the latest integrated WheelSystem technology, and a new aero-engineered Contact SLR composite handlebar to make it even faster against the wind.

FROM THE TOUR DE FRANCE TO YOUR LOCAL KOM, NO OTHER ROAD BIKE IN THE WORLD DOES IT ALL BETTER THAN THIS LEGENDARY WINNER. CHOSEN BY WORLDTOUR PROS LIKE SIMON YATES, IT’S THE ULTIMATE ALL-ROUNDER FOR THE PERFORMANCE OBSESSED. KEY PERFORMANCE FACTORS Class-leading efficiency Combining best-in-class stiffness-to-weight with strategically placed aero-tube shaping, this frameset is engineered for faster climbing, explosive acceleration, and unyielding pedaling stiffness for race-winning performance. Advanced aerodynamics This is where the TCR’s most quantifiable gains can be found compared to previous generation models. Every tube shape was analyzed, engineered, and tested to create an overall structure with significantly lower drag at a wider range of yaw angles. Total control Integrated disc brakes deliver smooth, powerful stopping power and modulation for added control in variable weather and road conditions. Flat mounts and new thru-axles boost stiffness and improve overall handling, while added frame and fork clearance allows for larger diameter tires up to 32mm.
