A self-adjusting bolt action skewer clamp for a bicycle trainer includes a hollow, outer support member and an inner engagement member located inside the support member. The support member has a helical slot with a pocket at one end. The inner engagement member is attached to a handle via a carrier contained within a passage defined by the inner engagement member, and the handle can slide within the helical slot such that the inner engagement member will extend past the support member as the handle is rotated around the helical slot. Once it reaches the pocket, the handle will remain locked in place. The clamp tightens onto a rear axle of the bicycle. The spring allows the bicycle trainer to accommodate bicycles of various sizes without adjustment.
