Giant Contact SL D-Fuse

Handlebar

The handlebar and stem are where your hands steer the bike. Their width and length set how upright or stretched out you sit.

Giant Approach

Saddle

The saddle and seatpost carry your weight. The height of the seatpost sets your pedalling position.

Advanced-grade composite

Frame

The frame is the bike's backbone: every other part is fixed to it. Its material and shape decide its weight and how it feels to ride.

Advanced-grade composite

Fork

The fork holds the front wheel. A suspension fork absorbs bumps at the front; its travel is how far it can compress.

Shimano BR-RS405 hydraulic · 160 mm

Brakes

Brakes slow the bike. Disc brakes squeeze a rotor fixed to the wheel hub; rim brakes squeeze the wheel rim itself.

Shimano CUES U6030 · 10 speeds

Drivetrain

The drivetrain turns your pedalling into motion: the cranks, the chain, the cassette and the derailleur that changes gear.

Giant Gavia Fondo 1

Tyres

Tyres are the bike's only contact with the ground. Their width and tread decide grip, comfort and rolling speed.

Weight
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
