Building fitness and taking care of your health has never been more fun. This lightweight flyer combines the agility of a road bike with the added confidence and control of a flat handlebar setup.
The perfect balance of road bike speed and city bike versatility. Built on a lightweight ALUXX SL aluminium frameset with a smooth-riding composite fork, this new flat-bar road bike puts the rider in a comfortable position that’s smooth and efficient. The D-Fuse seatpost helps smooth out rough roads, and handlebar grips help keep your hands comfortable on longer rides. The fast-rolling wheels can fit high-volume tyres up to 32mm in width. Powerful disc brakes give you added control in all types of weather, and easy-to-use rack mounts make FastRoad SL a smart choice for commuting, fitness riding and weekend adventures.
Key Performance Factors
Light and agile
ALUXX SL aluminium frame with updated geometry paired with a composite fork minimises weight and produces a quick, nimble ride quality.
Smooth and comfortable
Innovative D-Fuse seatpost absorbs road vibrations, and ergonomic bar ends protect your hands, keeping them comfortable on longer rides.
Easy to accessorize
Smart-mount rack and fender system lets you customise the bike for fitness riding, commuting or long-range adventures.
Techs & Features
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
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.
