Tap a number to see the part.

Handlebar

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

Bridge Comp

Saddle

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

PNW Loam OE Dropper

Dropper post

A dropper post lowers the saddle from a remote on the handlebar, so you can move freely on descents; raised again, it brings back your pedalling height.

M5 Alloy chassis and rear-end

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.

FOX DHX Factory

Rear shock

The rear shock lets the back wheel move over bumps. Its travel is how far the rear wheel can move; it is tuned to the rider's weight.

FOX FLOAT 38 Factory · 160 mm

Fork

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

TRP DH-R EVO · 220 mm / 203 mm

Brakes

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

Shimano SLX · 12 speeds

Drivetrain

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