Alloy handlebars
Handlebar
The handlebar and stem are where your hands steer the bike. Their width and length set how upright or stretched out you sit.
Specialized Bridge Comp with Mimic
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.
FOX FLOAT X 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
Fork
The fork holds the front wheel. A suspension fork absorbs bumps at the front; its travel is how far it can compress.
Shimano Deore XT brake · 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 XT Di2 · 12 speeds
Drivetrain
The drivetrain turns your pedalling into motion: the cranks, the chain, the cassette and the derailleur that changes gear.
61 mm
Tyres
Tyres are the bike's only contact with the ground. Their width and tread decide grip, comfort and rolling speed.
Specialized SL 1.2 Custom Rx Trail Tuned
Motor
The motor adds its power to the rider's effort. It sits either at the cranks or in the rear wheel hub; its torque, in newton-metres, tells how hard it can push on a climb.
Specialized SL1-320
Battery
The battery stores the energy the motor uses. Its capacity is given in watt-hours (Wh); how far it lasts depends on the rider, the terrain and the assist level.
