Bike suspension: definition, types, how to choose and maintain

What is suspension in a bike?

Suspension in a bike refers to a system of components, including the front suspension fork and rear shock, that absorb impacts from rough terrain to enhance comfort, control, and traction. Suspension was first introduced in mountain bikes in the late 1980s, primarily in the U.S., by innovators like Paul Turner (RockShox founder), to help riders tackle trails more efficiently and reduce rider fatigue, and has since evolved into advanced air, coil, and electronically controlled systems for various cycling disciplines.

What is front suspension in the bike?

Front suspension in a bike refers to the suspension system located in the fork, designed to absorb shocks and vibrations from the front wheel when riding over rough or uneven terrain. Front suspension became popular in the early 1990s with the rise of mountain biking in the U.S., pioneered by companies like RockShox, to improve rider control, comfort, and safety by reducing impact forces transferred through the handlebars.

What is rear suspension in the bike?

Rear suspension in a bike refers to the shock-absorbing system integrated into the rear triangle of the frame, typically using a shock absorber to dampen impacts from the rear wheel. Rear suspension gained prominence in the mid-1990s through innovations by brands like Specialized and Santa Cruz in the U.S., aiming to enhance traction, control, and comfort on technical trails by isolating the rider from bumps and terrain irregularities.

What is dual suspension in the bike?

Dual suspension in a bike, also known as full suspension, refers to a design that incorporates both front suspension (in the fork) and rear suspension (in the shock) to absorb impacts from rough terrain. Dual suspension bikes became popular in the 1990s through developments by brands like Trek and Cannondale in the U.S. and Europe, aiming to maximize rider control, comfort, and traction in mountain biking by smoothing out both front and rear impacts on trails and descents.

What is lockout and preload on bike suspension?

Lockout and preload on bike suspension are key tuning features that help riders adapt suspension performance to different terrain. Lockout is a mechanism—typically found on the fork or rear shock—that temporarily disables suspension movement to improve pedaling efficiency on smooth roads or climbs, first popularized by brands like RockShox in the late 1990s. Preload refers to the initial tension applied to the suspension spring (coil or air), allowing riders to adjust sag based on their weight and riding style, a concept refined over decades to balance comfort, responsiveness, and control.

How do bike suspensions work?

Bike suspensions work by absorbing shocks and vibrations through a combination of springs (coil or air) and dampers (oil or air chambers) that compress and rebound as the wheel encounters uneven terrain. The suspension system—including forks for front suspension and shock absorbers for rear—converts kinetic energy from impacts into controlled heat or displacement, reducing rider fatigue, improving traction, and enhancing bike control across varied surfaces.

How do bike suspension forks work?

Bike suspension forks work by using a combination of springs (coil or air) and damping systems (usually oil-based) within the fork legs to absorb vertical impacts from the front wheel. As the fork compresses under load, it reduces the force transmitted to the rider by dissipating energy through the damper and then smoothly rebounds, improving traction, steering control, and comfort on rough or uneven terrain.

How does rear suspension work on a mountain bike?

Bike rear suspension on a mountain bike works through a pivoting frame linkage connected to a rear shock absorber, typically using either an air or coil spring combined with a damping system to control compression and rebound. As the rear wheel encounters bumps or drops, the suspension compresses to absorb impact forces, converting kinetic energy into heat via hydraulic damping and allowing the wheel to maintain traction while minimizing rider fatigue and improving control on rough terrain.

How does a full-suspension mountain bike work?

Bike full-suspension mountain bikes work by combining a front suspension fork and a rear shock absorber to absorb impacts from both wheels, using mechanical linkages, springs (air or coil), and hydraulic dampers to manage compression and rebound forces. This dual system distributes energy from rough terrain across the frame, improving traction, reducing rider fatigue, and maintaining control and stability through technical descents, jumps, and uneven trails.

Does bike frame shape affect suspension?

Yes, bike frame shape does affect suspension because it determines the geometry, pivot placement, and leverage ratio, which all directly influence how the suspension compresses, rebounds, and transfers forces. Specific designs like Horst Link, single pivot, or VPP (Virtual Pivot Point) are integrated into frame architecture to optimize travel efficiency, pedaling performance, and shock absorption based on intended riding style and terrain.

How important is suspension on a bike?

Suspension is critically important on a bike, especially for mountain, downhill, enduro, and trail bikes, because it absorbs shocks from uneven terrain, improves control, traction, and rider comfort.
