Abstract
A bicycle can include a suspension system with a shock absorber. The shock absorber can have a sag position which can be adjustable. Sag refers to the amount of movement experienced by the suspension under a static load, such as that of the weight of a rider. Methods and systems to set sag can include at least one valve in fluid communication with a gas chamber of the shock absorber. In some embodiments, the at least one valve can be used to automatically set the sag position based on an individual's weight and riding position.
Claims20
A bicycle assembly comprising:
- a shock absorber comprising:
- a gas spring assembly having an interior surface;
- a movable piston forming a seal with the interior surface and configured to move along the interior surface;
- at least one valve for inflating and deflating the gas spring assembly with fluid;
- at least one valve port configured to establish fluid communication between the gas spring assembly and the at least one valve;
- wherein the gas spring assembly is divided by the piston into a first chamber and a second chamber, the first and second chambers configured to be determined at least in part by the position of the piston within the gas spring assembly, and the at least one valve port being positioned to communicate with the first chamber when in a given uncompressed position and communicate with the second chamber and not the first chamber when in a first compressed position.
