Giant Sport Flat

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 ErgoContact

Saddle

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

ALUXX-grade aluminum

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.

Tektro HD-R280 · 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

Drivetrain

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

Maxxis Re-Fuse

Tyres

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