A hub assembly, including: an axle with an axial opening; a hub shell; a frame, including first and second frame members with respective first and second retaining surfaces; and a control shaft within the axial opening. The control shaft includes: an engagement end; a clamping end with an enlarged head portion with an inwardly facing grip face; a shank extending between the engagement and clamping ends; first and second engagement surfaces proximal the engagement and clamping ends respectively. The second frame member includes an open slot to receive the control shaft. The control shaft is axially displaceable between: a retracted position radially disengaged from both first and second frame members; and a pre-engaged position, where the first and second engagement surfaces are overlapping the first and second retaining surfaces in respective first and second radial engagements to radially retain the hub assembly with the first and second frame members. |
