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.

The bicycle further includes a first fairing member protruding outward from the frame member and having a side surface defining an aerodynamic trailing edge and a second fairing member detachably mounted on the first fairing member such that the side surface is exposed.

Abstract: A bicycle that including front and rear wheels and a frameset supported by the wheels. The frameset including a main frame with a seat tube having a width, a fork that couples the main frame to the front wheel, and a seatstay assembly. The seatstay assembly including first and second seatstays positioned on opposing sides of the rear wheel and on opposing sides of the seat tube. A front end of the first seatstay is spaced from a front end of the second seatstay by a distance greater that the width of the seat tube. The frameset also including a suspension mount that is detachably secured to the front end of the first seatstay and a suspension member that is pivotally coupled to the suspension mount.

Abstract: A damper for a bicycle having a primary unit and a remote unit that, in some arrangements, is substantially entirely outside of the primary unit. The primary unit includes a damper tube, a spring chamber, and a piston rod that supports a main piston. The main piston is movable within the damper chamber of the primary unit. The main piston and the damper tube at least partially define a compression chamber. The remote unit comprises a remote fluid chamber and, in some arrangements, an inertial valve within the remote unit. The inertial valve is preferably responsive to terrain-induced forces and preferably not responsive to rider-induced forces when the shock absorber is assembled to the bicycle.
