Abstract
A suspension assembly for a cycle having improved stability includes a steering fork having a first arm and a second arm, each of the first arm and the second arm having a fixed pivot and a shock pivot, the space between the first arm and the second arm defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit has a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. The first gas piston area is not equal to the second gas piston area.
Claims8
A suspension assembly for a cycle, the suspension assembly comprising:
- a steering fork, the steering fork having a first arm and a second arm, each of the first arm and the second arm having a first end and a second end;
- a shock absorber having a damper body and shock gas spring comprising a shock spring body and a shock gas piston having a first gas piston area, the shock spring body being sequentially arranged along a substantially common central axis with the damper body, the shock absorber including a first shock mount and a second shock mount, the first shock mount being connected to the first arm, the second shock mount being pivotably connected to a shock link, and the shock absorber being located on the first arm;
- a spring unit, having a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area, a first spring mount and a second spring mount, the first spring mount being connected to the second arm, the second spring mount being pivotably connected to a spring link, and the spring unit being substantially located on the second arm;
- wherein the suspension assembly has a trailing link orientation, a fixed pivot being forward of a corresponding floating pivot, and the first gas piston area and the second gas piston area are unequal.
