From the superior stiffness-to-weight ratio of its Advanced SL composite frame to its integrated disc brakes including flat mounts and thru-axles—everything about this bike screams high performance. The Variant integrated seatpost balances efficiency and compliance. Proven Compact Road geometry, an OverDrive 2 steerer tube, and the massive MegaDrive downtube all work together to deliver legendary handling that’s synonymous with the TCR name.
Professional-grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including: Continuous Fiber Technology to add strength while reducing weight; Carbon Nanotube Technology resin to improve impact resistance; and Fusion Process for lighter, stronger frame junctions.
Every tube shape in the Advanced SL-grade composite frame is engineered to minimize weight, maintain stiffness and improve overall ride quality.
Complete composite construction and a minimalist design reduces weight while increasing stiffness. The redesigned OverDrive 2 steerer tube positions the lower bearing higher in the headtube, resulting in an improved transfer of force to the frame for sharp steering and cornering capabilities plus a smooth overall ride quality.
The frame and fork are engineered specifically for flat-mount disc brakes, including front and rear 12mm thru-axles for the most reliable braking and handling in all types of weather and road conditions.
A massive rectangular-shaped downtube links together the OverDrive front end and PowerCore bottom bracket. This precisely engineered tube shape yields optimal steering and pedaling stiffness while minimizing overall frame weight.
The oversized bottom bracket/chainstay area features a fully integrated 86mm wide BB design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Specifically engineered for the needs of competitive road racers, Variant’s refined shape and integrated design result in a ride quality that perfectly balances compliance and efficiency.
New internal cable routing with larger ports and a tool-free bottom bracket guide, designed for easy cable installation without any added weight.
Giant’s SLR Disc WheelSystem and the all-new Gavia SLR tubeless ready tires combine seamlessly to deliver a new level of efficiency, comfort and control.
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
