Cycle wheel suspension assembly having gas pistons with unequal gas piston areas

A suspension assembly for a cycle, the suspension assembly comprising:

• a steering fork, the steering fork having a steering axis, 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 first gas piston area and the second gas piston area are unequal, and
• wherein, a mechanical trail distance, which is a distance between a ground contact point of a wheel connected to the wheel mount and the steering axis, increases as the suspension assembly compresses relative to a fully extended state.
