Bike type
Full-suspension bike
A mountain bike with suspension at both ends. The rear shock keeps the back wheel on the ground over roots and rocks, which means more grip, more control and less fatigue.
Also known as: full suspension, dually, full-sus

How it works
The rear wheel sits in a swingarm that pivots on the frame and is controlled by a rear shock. A linkage decides how the wheel moves and how the bike reacts to pedalling and braking — each brand's design is a different answer to that.
How much travel
- 100–120 mm: fast cross-country and marathon bikes.
- 120–150 mm: trail bikes that climb and descend equally well.
- 150–180 mm: enduro bikes for steep, rough descents.
- 180–200 mm and more: downhill and bike-park bikes.
Worth knowing
A full-suspension bike only works as well as it is set up: start with sag, then rebound. It also has pivots and bearings to look after, which a hardtail does not.
