The TCR Advanced 1 continues Giant’s legacy of performance-driven road bikes, delivering class-leading efficiency and all-round versatility in a lightweight, carbon-framed package. The Advanced-Grade Composite frame offers a superb stiffness-to-weight ratio, designed to maximise power transfer on climbs and acceleration, while the refined aero tube shaping reduces drag across a range of riding conditions.
Every line and surface of the frame has been optimised for aerodynamic gains without compromising ride quality. The result is a fast, agile bike that responds instantly whether sprinting, cornering or climbing steep gradients.
The full composite fork with Giant’s OverDrive steerer adds front-end stiffness and precision, keeping the bike composed and predictable even at speed. The Shimano 105 Di2 12-speed drivetrain provides crisp, effortless shifting with the touch of a button, ensuring smooth gear changes under load. Paired with Shimano 105 hydraulic disc brakes, the TCR Advanced 1 offers excellent braking control in wet or dry conditions, giving riders complete confidence in every descent.
Rolling on Giant’s P-R1 Disc alloy wheels, the bike balances lightweight performance with durability. The Gavia Course 0 tubeless tyres allow lower pressures for better comfort and grip while reducing the risk of punctures — perfect for long training rides or club runs on variable road surfaces.
The finishing kit includes Giant’s Variant composite seatpost, which adds compliance for comfort without sacrificing efficiency, and a Giant Approach saddle to support long days in the saddle.
Every element of the Giant TCR Advanced 1 reflects Giant’s commitment to performance and reliability. It’s an ideal choice for riders who want the efficiency and handling of a race bike, with the everyday usability to make every mile feel fast and rewarding.
