Understanding Suspension Forks

Suspension forks are an essential component of any mountain bike. They are designed to absorb shocks and vibrations that occur while riding over rough terrains, providing a smoother and more comfortable ride.

There are several key components of a suspension fork:

  • Stanchions: These are the long tubes that slide in and out of the fork legs. They are responsible for guiding the fork’s movement and providing stability.
  • Lower Legs: The lower legs hold the stanchions and house the rebound and compression damping mechanisms.
  • Crown: The crown connects to the top of the fork legs and provides stability and strength to the fork.
  • Spring: Suspension forks can have either coil or air springs. The spring absorbs the impacts and determines the amount of travel the fork has.
  • Damping: Damping controls the speed at which the fork compresses and rebounds. It helps to regulate the fork’s movement and prevent it from bouncing too much.
  • Travel: Travel refers to the distance the fork can compress and rebound. It is measured in millimeters and determines how much shock absorption the fork can provide.
