Abstract: A leverage curve progression adjustment assembly for a rear suspension of a two wheeled vehicle, such as a mountain bicycle, adjusts the rate of change (slope/progression) of the leverage curve for the vehicle's suspension linkage while maintaining the same leverage ratio at the suspension's fully extended position. The leverage curve progression is adjusted by translating the first and second mounting locations of a spring/damper member along an axis of the spring/damper member using mounting hardware segments with spring/damper mounting holes positionable at multiple locations, such as flip chips with offset mounting holes, and/or mounting plates with mounting holes located at different locations.

Abstract: A bicycle rear suspension based on a four bar configuration comprises an upper connecting member, a rear axle floating member, a lower connecting member, an upper shock actuation member, a pushrod member, and a damper member. A pivotable coupling couples a first location on the upper shock actuation member to a location on the front triangle, another pivotable coupling couples a second location on the upper shock actuation member to a first location on the pushrod member, and another pivotable coupling couples a second location on the pushrod member to a location on the lower connecting link member. The upper shock actuation member is pivotably coupled to the damper member. The upper shock actuation member and the pushrod member and the geometries of their respective pivotable couplings allow the leverage curve for the suspension to be defined independently of their kinematic traits, thereby providing improved rider feel and/or performance.
