Abstract
Locking the headset of a steering post of a bicycle is accomplished by this invention where the steering post or threaded body projects coaxially through a cylindrical journal mounted at the front end of the bicycle frame. Bearing cups are secured in each end of the journal to accommodate thrust bearings. Each thrust bearing in turn is engaged by a cone. The lower cone is mounted stationary on the fork-steering post of the bicycle while the upper cone is threaded engaged to the mounting post body and is drawn hand tight against the upper thrust bearing. The upper cone is locked against rotational movement by a lock nut threaded on the post body above the upper cone and spaced from the upper cone. The locking configuration is achieved by one or more screws extending through an opening in the lock nut and engaging the upper cone to jam the threaded connections between the lock nut, upper cone and steering post body.
