Dual-suspension, also known as full suspension, refers to a bicycle design that features both front and rear suspension systems. This setup allows for better shock absorption and improved traction on rough terrain, making it ideal for mountain biking and off-road cycling. The front suspension typically consists of a fork with springs or air chambers, while the rear suspension includes a shock absorber connected to the frame. The main advantage of dual-suspension bikes is enhanced comfort and control during rides over bumps, rocks, and roots. This design helps to keep the tires in contact with the ground, providing better stability and handling. Popular brands like Trek and Specialized offer a range of dual-suspension models for various riding styles.
