1. Wheels Handlebar Seat Shock Linkages Pivots Parallel Linkages Suspension design allowing 14 inches of vertical rear wheel travel Jeff Burton Un-compressed State

2. Wheels Linkages Shock Pivots Parallel Linkages Plus Wheel travels slightly rearward through travel Shock linkages do not have to hold wheel laterally Minus Complex Top tube must allow for clearance of vertical shock position Jeff Burton Compressed State

3. Shock Linkages Pivots Wheels Handlebars Top Tube Shock A shock positioned horizontally on the top tube dampens the motion of the rear wheel Jeff Burton Uncompressed State

4. Shock Linkages Pivots Wheels Pros Fewer moving parts Wheel will not hit linkages Cons Rear wheel follows circle and gets close to seat Jeff Burton Top Tube Shock Compressed State

5. Double Rear Shock A simple two spring suspension system that allows long travel with few pivot points Advantages Fewer parts Simple Design Disadvantages Require 2 shocks Accurate spring force Pivot Uncompressed State Chat Huynh

6. Double Rear Shock Shock Pivot Compressed State Chat Huynh

7. Progressive Suspension A long travel suspension that uses three springs to create a progressive spring rate. Uncompressed State Simon Radomski

8. Progressive Suspension Compressed State Plus Very difficult to bottom out Allows for 14” of travel Minus Added weight and complexity of extra springs Inherently less frame stiffness than single shock design Simon Radomski

9. Progressive Suspension Relocated Main Gears - Subsystem The Larger Gears are relocated higher on the frame in order to get more ground clearance. Relocated Main Gears - subsystem Plus  Protects large chain rings from damage  Adds extra ground clearance Minus Inherently more chain slop Needs complex chain tensioning methods Simon Radomski

10. Double Shock Design A design with two shocks incorporated into the upper suspension arm. Pros + Design allows for a higher location of pedals, preventing the chassis from hitting the ground when shocks are completely compressed + Relatively Simple + Use of two shocks allows for more control + Large shock travel distance Jon Gutierrez Uncompressed State

11. Cons: - Center of mass is raised - Rider position is slightly different from usual position - Uses two shocks possibly making design more expensive Jon Gutierrez Compressed state
