Other advances in design include adjustable travel, allowing riders to adapt the fork's travel to the specific terrain (e.g.
This amount of travel is now common for cross-country disciplines, whereas downhill forks typically offer 200 mm or more of travel for handling the most extreme terrain. When suspension forks were introduced, 80–100 mm of travel was deemed sufficient for a downhill mountain bike. The amount of travel available has typically increased. Telescopic suspension forks have become increasingly sophisticated. For instance, manufacturers produce different forks for cross-country (XC), downhill (DH), freeride (FR) and enduro (ND) riding which all have different demands for amount of travel, weight, durability, strength, and handling characteristics. The specifics of the suspension depend on the type of mountain biking the fork is designed for and is generally categorized by the amount of travel. Front suspension Ĭannondale Lefty fork Telescopic įront suspension is often implemented using a telescopic (i.e., telescoping) fork. However, the stiffness was able to be controlled and functioned well except in cold weather. The fork used elastomers and had no dampening effect, just a spring. Front suspension first appeared on a bike in 1990 when the founder of Manitou, Doug Bradburry, designed and built the first front suspension fork in his garage. This bike had a rigid front fork as the technology to build a fork with a shock wasn't here yet, at least for a mountain bike. A simple rear shock with a single pivot was designed by Brian Skinner and implemented onto a bike called the MCR Descender. It wasn't until 1983 when the first true suspension design came around. He was involved with Air Springs Ltd and they developed an air sprung motorcycle in 1909, but they also loaned an air sprung bicycle to the correspondent to show how good the suspension was.
In 1901 the famous author on bicycles Archibald Sharp patented air suspension for bicycles. Bicycle designers intentionally make frames in such a way that the frame itself can absorb some vibrations.īesides providing comfort to the rider, suspension systems improve traction and safety by helping to keep one or both wheels in contact with the ground.Īs early as 1885, the Whippet brand of safety bicycle was notable for its use of springs to suspend the frame. Bicycles with only rear suspension are uncommon although the Brompton folding bicycle is equipped with rear only suspension.Īlthough a stiffer frame is usually preferable, no material is infinitely stiff and therefore any frame will exhibit some flexing. When a bicycle has no suspension it is called rigid.

Bicycle suspension is used primarily on mountain bikes, but is also common on hybrid bicycles.īicycle suspension can be implemented in a variety of ways, and any combination thereof:īicycles with only front suspension are referred to as hardtail and bicycles with suspension in both the front and rear are referred to as dual or full suspension bikes. Bicycle suspension is the system, or systems, used to suspend the rider and bicycle in order to insulate them from the roughness of the terrain.
