Topstone Gravel Bike Alloy Range

Handcrafted with Advanced-grade composite material, the Defy Advanced is engineered with tube shapes that are optimized to absorb road shocks and vibrations. Even with its smooth ride quality, it still delivers a lightweight, stiff and lively feel when you’re climbing, accelerating and cornering. It’s made with a specific carbon layup to give it an efficient, high-performance ride quality that helps you push new limits of endurance. The D-Fuse seatpost and handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road. A tubeless Giant WheelSystem and tyres boost speed and efficiency with a reduced risk of flats. And for added control, it features integrated disc brakes with flat-mount disc brake tabs and 12mm thru-axles.

With the perfect blend of stiffness and compliance, Defy Advanced Pro delivers a smooth, fast ride quality even on rough roads. Its innovative technologies include a D-Fuse composite seatpost and Contact SLR D-Fuse carbon composite handlebar (Pro 1 and Pro 2 models). These integrated cockpit components work as a system to add compliance and reduce road shocks and vibrations. The Advanced-grade composite frame is also integrated for disc brakes, with flat-mount disc brake tabs and 12mm front and rear thru-axles, plus clearance for high-volume tyres up to 35mm. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision, while the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedalling efficiency.
