Abstract: A dropper post assembly can include an outer tube and an inner tube with a lower end that is within the outer tube and include a tube engagement. A spring cartridge assembly can include: a cartridge tube providing a cylinder; a piston movably received within the cylinder to provide a first chamber a lower side of the piston and a second chamber between the piston; a cartridge rod; and a second engagement member configured to releasably engage the tube engagement member thereby fastening the cartridge tube to the lower end of the inner tube so that the cartridge tube is axially fixed to the inner tube and movable with the inner tube relative to the outer tube.

Abstract: A dropper post assembly for supporting a bicycle seat can include an outer tube and an inner tube telescopically receivable in the outer tube and slidable within the outer tube between a retracted position in which a lower end of the inner tube is proximate a lower end of the outer tube and an extended position in which the lower end of the inner tube is axially spaced from the lower end of the outer tube. An actuator assembly may include an actuator body having a mounting portion connected to the lower end of the outer tube and a cartridge rod receiving portion, and may be configured so that when the inner tube is in the retracted position at least the upper surface of the cartridge rod receiving portion is nested within the inner tube.

Abstract: A dropper post assembly for supporting a bicycle seat may have an outer tube and an inner tube having a clearance portion and an upper end that includes an inward facing axial stop surface that defines a laterally extending abutment plane. A spring cartridge assembly has a cartridge cross-sectional that is less than 90% of the interior cross-sectional area of the clearance portion. A lower engagement member is disposed toward a lower end of the inner tube and substantially fills a lateral between lower end of the cartridge tube and the inner tube. A post head member has a front fastening aperture, a lowermost part of which lies in a laterally extending post head plane that is disposed axially inboard from the abutment plane.

Abstract: An elongate, tubular handlebar can include a laterally extending central mounting portion, a tubular left body section extending laterally from one side of the mounting portion a tubular right body section extending laterally from the other side of the mounting portion. The right body section may have an elongate, tubular right control portion extending laterally from an inboard end to an outboard end and configured to support a generally laterally extending grip and a right transition portion having a non-circular, transition cross-sectional shape at a first location defining a first width measured in a first direction and a second width that is greater than the first width and is measured in a second direction. Whereby right body section has a first stiffness in the first direction and a second stiffness that is greater than the first stiffness in the second direction.

Abstract: A dropper post assembly for supporting a bicycle seat may include an outer tube extending along a post axis and an inner tube configured to be axially slidable within the outer tube by a travel distance that is at least 200 mm between a retracted and an extended position. The inner tube may have an outer diameter that is between 25.5 mm and 30 mm, and when the inner tube is in the extended position a moment of inertia (lx) taken adjacent the seat collar is at least 11,000 mm4. A spring cartridge may have an unlocked configuration in which the spring cartridge exerts an extension force (FE) on the inner tube that biases the inner tube toward the extended position, and a locked configuration in which the spring cartridge is operable to generate a degassing force (FD) of between about 90 lbs and about 140 lbs to resist movement of the inner tube toward the retracted configuration. An actuator may be operable to change the spring cartridge between the locked configuration and the unlocked configuration.

Abstract: There is described a bicycle seat post assembly in which the travel distance of the seat post can be adjusted. The seat post assembly includes an outer tube that is configured to telescopically receive an inner tube. The inner tube is axially slidable relative to the outer tube between a retracted position and an extension position, the extension position being determined by an extension assembly in which a slider engages an upper retainer surface, thereby setting the upper limit of axial extension of the inner tube. The extension of the inner tube can be limited to an intermediary extension position that lies between the retracted and extension positions by an insertable extension stopper that is positionable under the upper retainer surface.

Abstract: A seat attaching may include a lower seat clamp that is moveable relative to a post head member about a pivot axis and includes: a mounting portion having a bearing surface configured to engage a corresponding cradle portion of the post head member a first channel configured to receive a first seat rail of a bicycle seat and a second channel configured to receive a second seat rail of a bicycle seat. An upper seat clamp may include: a central portion overlying the mounting portion; a first extension portion disposed on a first side of the central portion and having a first retainer surface overlying and facing the first channel to retain the first seat rail within the first channel and having a first apex; and a second extension portion disposed on a second side of the central portion and having a second retainer surface overlying and facing the second channel to retain the second seat rail within the second channel and having a second apex. An upper plane may contain both the first apex and second apex and may be substantially parallel to the pivot axis. The upper plane may be offset below the pivot axis and intersecting the bearing surface. A first fastener may be used to secure the upper seat clamp to the post head member.
