Mountain bike suspension serves two main purposes: to improve the rider’s control over the bike and to absorb shock from the terrain. There are several types of suspension designs used on mountain bikes, including:
Hardtail: This type of suspension has a shock-absorbing fork at the front of the bike, but no suspension at the rear. It’s generally less expensive and lighter than full-suspension bikes, and it’s a good choice for cross-country riding or for riders on a budget.
Full-suspension: As the name suggests, this type of suspension has shocks at both the front and rear of the bike. Full-suspension bikes are generally more expensive and heavier than hardtails, but they offer better traction and a more comfortable ride. They’re a good choice for downhill and technical riding.
Single-pivot: This is a basic full-suspension design that uses a single pivot point to allow the rear triangle to move. It’s a simple and reliable design that’s commonly used on budget full-suspension bikes.
Dual-pivot: This design uses two pivot points, which allows for more precise control over the suspension. It’s generally more expensive and complex than single-pivot suspension, but it offers better performance.
Four-bar linkage: This design uses four pivot points and a linkage system to control the suspension. It’s more expensive and complex than single-pivot and dual-pivot suspension, but it offers good performance and is commonly used on high-end full-suspension bikes.
Virtual pivot point (VPP): This is a more complex four-bar linkage design that uses two short linkages to control the suspension. It’s known for its efficient pedaling and good traction, and it’s commonly used on high-end full-suspension bikes
