Roval Alpinist Carbon Handlebar

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.

FACT 12R

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.

Future Shock

Fork

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

Shimano Dura-Ace BR-R9270 hydraulic disc

Brakes

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

Shimano Dura-Ace R9250 · 12 speeds

Drivetrain

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

Mondo TLR Endurance Tire

Tyres

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