Air springs for bicycle components

Air springs for bicycle components are described herein. An example air spring includes a tube, a first sealhead coupled to the tube, a second sealhead coupled to the tube such that a sealed pressure chamber is formed in the tube between the first and second sealheads, and a seal coupled to the second sealhead. The second sealhead and the tube are coupled along an axial interface locking length. The tube has a vent port. The seal is spaced from the vent port by a port seal gap that is less than the axial interface locking length such that as the second sealhead is being decoupled from the tube, the seal loses sealing contact with the inner surface to enable at least a portion of the sealed pressure chamber to be equalized with atmospheric air before the second sealhead is fully decoupled from the tube.

Bicycle seat with vibration isolation

A bicycle seat suspension can include one or more movable body members. The one or more movable body members can be configured to be operatively connected to a bicycle saddle. The one or more movable body members can be configured to change configuration when a load is applied to the bicycle saddle. The bicycle seat suspension can also include a vibration isolator. The vibration isolator can be configured to exhibit a non-linear stiffness profile including a region of quasi-zero stiffness. The vibration isolator can be operatively positioned such that, when the one or more movable body members change configuration responsive to a load being applied to the bicycle saddle, the one or more movable body members can engage the vibration isolator. As a result, the vibration isolator can isolate a person seated on the bicycle saddle from vibrations transferred through the bicycle saddle.
