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.
Reengineered with updated aerodynamic tube shaping in the headtube, downtube and fork, plus added clearance for larger diameter tires (up to 32mm), the new TCR Advanced Disc 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, including flat mounts and 12mm front and rear thru-axles, it’s an all-weather, all-conditions race machine to keep you at the front of the pack.
Key Performance Factors
Class-leading efficiency
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.
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. The result is a TCR that’s faster than ever in sprints and solo situations.
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 32mm.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.

Highlights
Combining lightweight composite frame engineering with strategic aero tube shaping and integrated disc brakes, the new TCR Advanced Disc series delivers versatile road racing performance. Here’s a look at its key technologies.

Advanced Composite
Truncated Ellipse Tubing
New 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.
Variant Seatpost
This proprietary seatpost design offers the perfect balance of light weight, superior ride quality, aerodynamics and easy saddle installation and adjustment.
Symmetric Composite Fork
The new 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.
Contact Handlebar
A Giant Contact aluminum handlebar provides a comfortable grip, outstanding ergonomics and minimal weight.
OverDrive
Giant’s original 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.
MegaDrive
A massive rectangular downtube forms the link between the OverDrive 2 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.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter-wide bottom-bracket design. Symmetric chainstays provide additional stiffness on the driveside and stability on the non-drivesides.
Giant Tubeless System
Updated Giant tubeless wheelset and tires for improved comfort, efficiency and safety right out of the box.
Disc-Brake Integration
The frame and fork are engineered with flat-mount disc-brake mounts for powerful, consistent braking performance in all conditions.

Technologies & Features
Advanced Composite Technology
Giant’s 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 of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
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.
MegaDrive
A massive rectangular downtube and oversized toptube work in unison to provide superior front end lateral and torsional steering precision. The precisely engineered, rectangular shaped downtube yields unprecedented steering and pedaling stiffness.
OverDrive
Giant’s original 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 for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
Variant Seatpost
This proprietary seatpost design offers an optimized balance of light weight, superior ride quality and simple adjustment to enhance the total race performance of the TCR road range.
