Tap a number to see the part.

Alloy Trail Stem

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 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.

FACT 11m carbon 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 FLOAT Performance Elite

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 36 Performance Elite · 140 mm / 150 mm

Fork

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

SRAM Maven Bronze · 200 mm / 180 mm / 200 mm

Brakes

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

SRAM GX Eagle Transmission Derailleur

Drivetrain

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