  • GEAR CHANGER ADJUSTMENT AND DEVICE
    Publication number: 20200346714
    Abstract: In an adjustment mode for a derailleur of a bicycle, acceleration values from an accelerometer of the derailleur are sampled as the derailleur moves through sprockets of a rear sprocket assembly. Acceleration signal powers are identified based on the sampled acceleration values, and potential rasping positions are identified based on thresholding of the acceleration signal powers. The identified potential rasping positions are compared to expected rasping positions, and adjustment for the derailleur is set based on a minimum error between the identified potential rasping positions and the expected rasping positions.

  • Adjustable seatpost
    Patent number: 10807667
    Abstract: A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.
