This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.

FastRoad SL
SPEED MEETS STABILITY
Highlights
The perfect balance of road bike speed and city bike versatility. Built on a lightweight ALUXX SL aluminum frameset, 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 ergo bar ends keep your hands comfortable on longer rides. The fast-rolling wheels can fit high-volume tires up to 32c, and they’re tubeless ready so you get a smoother ride, more grip, and fewer flat tires. 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.

ALUXX SL Aluminum Frame
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.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Flat Bar Positioning
Frame geometry is specifically engineered to produce a balanced feel that blends stable flat-bar positioning with speed and road acceleration.
D-Fuse seatpost
This proprietary composite seatpost with a D-shaped shaft dampens vibrations, resulting in a smooth, compliant ride quality.
Ergo-Max Bar End
The reengineered bar-end features a new ergo shape and integrated soft rubber on the palm zone to dampen vibrations.
Smart Mounting System
Rack mount is compatible with third party racks, making it versatile for various frame bags and accessories.
