A stem includes a quill with a quill length extending along an axis. A first quill end has a cradle configured to couple to a handlebar, and a second quill end has helical slots opposite one another. A base has a base length extending along the axis. The base is configured to receive the quill. A first base end has a bracket configured to couple to a steering mast. The base has apertures opposite one another, and a second base end has a groove extending along the axis. A pin is coupled to the base perpendicular to the axis through the apertures. A releasable clamp is sized to fit around a base outer diameter. The helical slots are configured to receive the pin and slidably guide the pin along the helical slots of the quill such that the quill is rotatable within the base and relative to the base.
