Mountain bike suspension refers to the system that absorbs shocks and bumps while riding on rough terrain. It typically consists of two main types: front suspension, which is found in the forks of the bike, and rear suspension, located in the frame. This technology helps improve traction, control, and comfort, allowing riders to navigate challenging trails more effectively. Suspension systems can be categorized into two main designs: hardtail, which has only front suspension, and full-suspension, which includes both front and rear suspension. The choice between these types depends on the rider's preferences and the type of terrain they plan to tackle.
