Roval Alpinist Cockpit II

Handlebar

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

S-Works Power with Mirror

Saddle

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

S-Works Aethos 2 FACT 12r Carbon

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.

S-Works Aethos 2 FACT 12r Carbon

Fork

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

SRAM RED E1

Brakes

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

SRAM RED AXS E1 · 12 speeds

Drivetrain

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

S-Works Turbo TLR Race Tire · 28 mm

Tyres

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