ABSTRACT:
This application relates to rear suspension system for bicycles, such as freeride, downhill and trail-style mountain bikes. The suspension system includes a rear suspension for coupling the rear wheel of the bicycle to the bicycle frame, a rear shock absorber disposed entirely in front of the seat tube of the frame and a linkage for operatively coupling the rear suspension to the rear shock absorber. The linkage intersects the longitudinal axis of the seat tube for transmitting rear suspension forces around the seat tube to the rear shock absorber. The seat tube is preferably continuous and is disposed so that the bicycle seat is adjustable over a full range of seat positions. The seat tube orientation ensures that the seat is movable between optimum biomechanical positions for both uphill pedaling and aggressive downhill freeriding. Additionally, the seat tube and rear suspension system are configured so that the rear wheel and rear suspension will not contact the seat tube, seat, or bicycle rider even when the rear suspension system is in a fully compressed, forward position. The shock absorber is preferably oriented in an orientation to maximize its stroke length. For example, the shock absorber may be oriented generally parallel to a top tube of the bicycle frame.
