Abstract: A bicycle wheel comprises a rim and a valve assembly. The rim includes a radially inner wall having an inner opening and a radially outer wall having an outer opening. A first portion of the rim includes a first securing feature (e.g., inner threads). The valve assembly is positioned in the inner opening and outer opening and includes a second securing feature (e.g., outer threads) engaging the first securing feature. The rim can include a plate that defines the first engaging feature. The valve assembly preferably includes a valve stem and a resilient bumper coupled to the valve stem and aligned with a second portion of the rim. The valve assembly can further include a seal member compressed between the valve stem and the rim. Preferably, the seal member is positioned in an annular groove in an underside of an enlarged head of the valve stem.

Abstract: A bicycle rim assembly includes a rim defining a central plane and comprising annular inner and outer walls. The outer wall includes first and second bead seats separated by a center well. First and second annular projections are spaced laterally from each other relative to the central plane and extend substantially radially outwardly from the outer wall. Each of the annular projections includes a radially outer face and a laterally inner face. Right and left covers are spaced from each other and are preferably coupled to the rim to cover at least a portion of the laterally inner face and the radially outer face of the first and second annular projections, respectively, and also the first and second bead seats, respectively. One or both of the right and left covers can be fiber reinforced. First and second pieces of tape can be overlapped and used to secure the covers to the rim.

Abstract: A device for sensing a bicycle pedaling torque input includes: a housing; a bearing defining a rotational axis; a bearing support member that positions the bearing with respect to the housing, the bearing support member including one or more beams; an output member configured to be coupled to a chain ring, the output member being coupled to an inner race of the bearing to enable the output member to rotate with respect to the housing about the rotational axis; a spindle configured to be coupled to a bicycle pedal crank, the spindle functionally coupled to the output member to enable a rider pedaling force applied to the spindle to cause rotation of the output member; and one or more strain gauges, each of the one or more strain gauges being coupled a beam of the bearing support member.
