Abstract: An inner-tube assembly that includes an inner-tube and a valve assembly. The valve assembly is configured to facilitate the inflation of the inner-tube, and the valve assembly includes a valve core and a valve housing. The valve housing has a lower portion coupled to the inner-tube and an opposite upper portion. At least part of an exterior surface of the lower portion is threaded and at least part of an exterior surface of the upper portion is unthreaded. In another aspect, the inner-tube assembly includes the inner-tube and a valve assembly. An attachment member couples the valve assembly to the inner-tube. The attachment member has a length and a width defining an aspect ratio of width/length, and the aspect ratio is less than about 0.50.

Abstract: A water bottle cage comprising two mating sections formed of injection molded plastic, is disclosed. The two sections define a bayonet snap assembly which maintains alignment of the two sections, permits easy pivotal joining and release of the two sections, and locks the two sections upon insertion of a water bottle. Alternatively, the two sections can be permanently joined, for example, by ultrasonic bonding.

Abstract: An improved bicycle headset is disclosed having ball bearing races sealed by O-rings against contamination by dust, dirt, moisture and the like. This bicycle headset includes a lower assembly comprising a lower cup fitted to the lower end of a head tube, a crown cone upon which the shoulder of a front fork bears, a lower ball bearing race positioned between the lower cup and the crown cone, and a lower O-ring seal mounted on the crown cone to isolate the lower ball bearing race from the external environment. Also included, is an upper headset assembly comprising an upper stationary cone fitted to the upper end of the head tube and an upper cup threadedly attached to the upper end of a fork tube. A weatherproof lock nut is tightened down against the top portion of said upper cup so as to lock the position of the upper cup on the fork tube about a handlebar stem, and seal the upper part thereof.
