An adjustable headstock arrangement 10 for adjusting a head tube angle relative to a mainframe of a cycle comprises a first headstock member 12 for attachment to the mainframe, and a second headstock member 14 pivotably mounted with respect to the first headstock member 12 such that the head tube angle (α, figure 4) of the second headstock member 14 may be adjusted between a first head tube angle α1 and a second head tube angle α2. The first and second headstock members 12, 14 comprise curvilinear engagement surfaces 18, 28 which allow the headstock angle α of the second headstock member 14 relative to the first headstock member 12 to be adjusted between a maximum headstock angle α and a minimum headstock angle α. The degree of curvature in the or each curvilinear engagement surface 18, 28 is such that a resultant headstock angle pivot axis (33, figure 4) is located forward of and perpendicular to a head tube longitudinal axis 24. Also claimed is a replaceable headstock arrangement.
