Choosing the Right Suspension Setup

Considerations for choosing suspension setup

Choosing the right suspension setup for downhill biking requires careful consideration of various factors. One important factor is the rider’s weight, as different shocks and forks have weight limits and need to be properly adjusted to provide optimal performance. Additionally, the type of terrain and riding style should be taken into account. Some trails may require a more robust suspension setup, while others may benefit from a lighter and more agile setup.

Travel length and its impact

The travel length of a suspension system refers to how much the fork or shock can compress and absorb impacts. Downhill bikes typically have longer travel lengths compared to other mountain bikes, ranging from 180mm to 220mm. A longer travel length allows for greater suspension travel, which in turn enables the bike to handle larger impacts and rougher terrain more effectively. However, it’s important to find the right balance, as excessively long travel can negatively affect climbing and pedaling efficiency.

Adjustability and customization

Having adjustable suspension settings allows riders to fine-tune their bike’s performance according to their preferences and the specific trail conditions. Suspension systems with adjustable features such as compression, rebound, and air pressure enable riders to optimize their bike’s performance for different terrains and riding styles. Customization options, such as the choice between coil and air shocks, also allow riders to tailor their suspension setup to their specific needs and preferences.

Features of Downhill Bike Suspension

Coil vs Air shocks

When it comes to choosing a rear shock for a downhill bike, riders often have the option of either a coil or air shock. Coil shocks use a metal spring to provide suspension, offering excellent sensitivity and robustness. They are known for their ability to handle large impacts and provide a smooth ride. On the other hand, air shocks use compressed air as the spring mechanism, providing a lighter and more adjustable option. Air shocks are often favored for their ease of adjustment and ability to fine-tune the suspension for different riders and terrain conditions.

Damping systems

Damping systems are an integral part of suspension setups, responsible for controlling the speed at which the suspension compresses and rebounds. Most downhill bikes feature adjustable damping systems, allowing riders to control the amount of compression and rebound damping to optimize the bike’s performance. High-quality damping systems ensure a smooth and controlled ride, preventing excessive bouncing or harsh impacts when encountering rough terrain.

Lockout mechanisms

While downhill bikes primarily focus on providing a supple and active suspension, some riders may find it beneficial to have a lockout mechanism. A lockout allows the rider to temporarily disable the suspension, essentially making it rigid. This can be useful for climbing steep sections or smooth terrains where suspension movement may cause energy loss. However, lockout mechanisms are less common on downhill bikes, as they are primarily designed for efficient descending rather than climbing.

Suspension linkage designs

The suspension linkage design on a downhill bike plays a significant role in determining how the suspension system functions. Different designs, such as single-pivot, four-bar, or horst-link, have distinct characteristics in terms of suspension performance, pedaling efficiency, and braking stability. Manufacturers often employ specific linkage designs to optimize the bike’s performance for downhill riding, ensuring maximum control, stability, and suspension responsiveness.

Key Components of Downhill Bike Suspension


The fork is a critical component of a downhill bike’s suspension system, responsible for absorbing impacts from the front wheel. Downhill bike forks are designed with robust construction and long travel to handle the demanding nature of downhill riding. They feature large stanchions and strong lowers to provide stability and durability. The fork’s performance, including its sensitivity and adjustability, greatly affects the overall control and handling of the bike.


The rear shock is another key component of a downhill bike’s suspension system. It absorbs impacts from the rear wheel, helping maintain traction and control. Rear shocks for downhill bikes are available in various types, including coil and air shocks as mentioned earlier. They are typically built with large-diameter shafts and increased oil volume to handle the increased forces encountered during downhill riding.


The swingarm is the component that connects the rear triangle of the bike to the rear shock. It plays a crucial role in transferring the forces from the rear wheel to the shock, allowing for the absorption of impacts and maintaining suspension performance. The swingarm design varies across different downhill bike models, with some featuring a single-pivot design for simplicity and efficiency, while others use more complex linkage systems for enhanced suspension characteristics.

Pivot points

Pivot points are the locations where different parts of the bike’s suspension system rotate or pivot. These points allow the suspension system to work effectively by allowing the necessary movement throughout its travel. The placement and design of pivot points directly influence the suspension’s performance characteristics, including sensitivity, anti-squat properties, and pedaling efficiency. Manufacturers carefully engineer pivot points to optimize the bike’s overall suspension performance.

Downhill Bike Suspension Tuning

Setting sag

Setting sag is a crucial step in tuning a downhill bike’s suspension. Sag refers to the amount of suspension travel that is used when the rider is in a static or neutral riding position. By adjusting the air pressure or preload on the suspension, the rider can achieve the desired sag, typically around 25-30% of the total travel. Properly setting sag ensures that the suspension is properly balanced and responsive to the rider’s weight and riding style.

Adjusting rebound

Rebound refers to the speed at which the suspension extends back to its original position after compression. It is essential to adjust the rebound damping to match the rider’s preferences and the terrain conditions. Too fast of a rebound can result in a bouncy and uncontrollable ride, while too slow can make the bike feel sluggish and unresponsive. Fine-tuning the rebound damping allows the suspension to recover quickly and maintain optimal traction and control.

Fine-tuning compression

Adjusting compression damping helps control the rate at which the suspension compresses when encountering impacts. High-speed compression damping affects larger, faster impacts, while low-speed compression damping helps with smaller, slower impacts and helps prevent excessive diving in the suspension during hard braking. Finding the right balance between the two allows riders to fine-tune their suspension for optimal performance on different terrains and riding styles.
