GUNNING FOR THE RACE WIN OR DIGGING DEEP FOR A PR, THIS COMPOSITE ROAD RACING BIKE GIVES YOU THE SPEED, EFFICIENCY AND CONTROL TO PUSH IT TO THE LIMIT, AND THEN A LITTLE BIT MORE.
KEY PERFORMANCE FACTORS
With an impressive stiffness-to-weight ratio and updated aero tube shaping, this frameset is engineered to give road racers and riders superior climbing capabilities, aerodynamic efficiency, and sprint stiffness for race-winning performance.
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.
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 the added frame and fork clearance allows for larger diameter tires up to 32mm.
Reengineered with updated aerodynamic tube shaping in the headtube, downtube, and fork, plus added clearance for larger diameter tires, this all-rounder delivers outstanding on-the-road efficiency. The Variant seatpost adds just enough compliance to give it a balanced, race-tuned feel on the road. And with its integrated disc-brake technology, it’s an all-weather, all-conditions race machine.
High-performance grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
TRUNCATED ELLIPSE TUBING
Strategically engineered airfoil sections in the frame and fork, developed through CFD and wind-tunnel testing, improve aerodynamic efficiency, reducing wind drag at a wider range of yaw angles compared to traditional teardrop shaped tubes.
This proprietary seatpost design offers the perfect balance of light weight, superior ride quality, and easy saddle installation and adjustment.
Advanced-grade composite fork features a symmetric design and aero shaping, along with disc-brake integration and increased clearance for tires up to 32mm. The design makes it lighter, stiffer and more aerodynamic.
Features modified cable routing to provide a smart balance of aerodynamics, rider ergonomics and hassle-free setup and maintenance.
Giant’s proven oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
A massive rectangular downtube forms the link between the OverDrive headtube area and the PowerCore bottom bracket. This precisely engineered, rectangular shape yields unprecedented steering and pedaling stiffness while optimizing aerodynamic flow over a standard water bottle.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter-wide bottom-bracket design. Symmetric chainstays provide additional stiffness on the drive-side and stability on the non-drive-side.
GIANT TUBELESS SYSTEM
Engineered with proprietary Dynamic Balanced Lacing, a composite WheelSystem, and tubeless tires for improved efficiency, comfort, and control in the most user-friendly and reliable system.
The frame and fork are engineered with flat-mount disc-brake technology for powerful, consistent braking performance in all conditions.
COMPACT ROAD DESIGN
Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward-sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
