The Glide Suspension Fork: Less Vibration, More Comfort, Better Health.

The Glide is the only suspension fork that maximizes vibration dampening in both horizontal and vertical directions and minimizes vibration transfer to the body of the rider.

  • Patented suspension element design is positioned at an angle to optimally dampen vibration.
  • Beautiful, sleek design available in standard fork (double-sided) or single-sided versions.
  • Offers 3 different durometers (elastomer hardness) based on the weight of the rider.
  • Forks are made of light-weight aluminum and the elastomer is made of durable polyurethane.
  • Only available on new TiLite chairs.

The Science Behind the Glide

The Problem

When your front caster hits a bump, forces are transferred in two directions - horizontally and vertically (yellow arrows). When averaged together, these forces impact your chair at an angle (red arrows).

The Suspension Solution

In order to address the vibrations from these impacts, suspension forks use a single pivot suspension system. This enables the fork to rotate in an arc around the pivot point as the suspension element absorbs the forces.

How Suspension Works

The single pivot suspension system rotates the direction of the impact forces as depicted by the red arrows going into the suspension element (at a right angle from the orginal forces). This facilitates the absobtion of forces into the suspension element.

The Innovation

The Glide is the only suspension caster fork that absorbs impact forces from both vertical and horizontal directions because its suspension element is angled to match the angle of the impact forces. This maximizes the effectiveness of the suspension element and its ability to minimize vibration transferred to the user.

The Glide: Background

For people in wheelchairs, an important barrier to optimal comfort is the shock and vibration experienced as one goes over bumps or rough surfaces. For those interested in minimizing shock and vibration, one solution is suspension forks. As illustrated above, however, currently available suspension forks reduce vibration only in the vertical plane while failing to address vibration from the horizontal plane.

Enter the Glide. To optimize vibration dampening in both directions, the Glide relies on a patented design that employs a suspension element that sits at an oblique angle – an orientation between the horizontal and vertical planes. Thus, the Glide is the only suspension fork that provides vibration dampening in both horizontal and vertical directions and in turn minimizes vibration transfer to the body of the rider. Less vibration means a more comfortable and healthier ride.

The Glide was invented and tested by researchers at the Human Engineering Research Laboratories, a joint venture of the University of Pittsburgh and the VA Pittsburgh Healthcare System.
