Giant Sport

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 Grit Jr

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.

SR XCT Jr. L20 · 63 mm

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-J2820 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.

MicroSHIFT Advent

Drivetrain

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

Kenda Amrak

Tyres

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

  • “Dirt skills start here. With a lightweight aluminum frame that has a low stand-over height and 20-inch wheels, the new STP 20 gives kids the confidence and maneuverability they need to start leaning into the turns, shifting their weight, and popping some air. It’s all the things that make riding fun.” — Frame

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.
