Abstract: A wheel bracket for holding a variety of objects, such as valve extenders and air hoses, in a desired position on a vehicle wheel rim. The wheel bracket comprises a first end for attaching to a wheel rim, a wheel portion for abutting a wheel rim and supporting a freestanding portion, and a second end. The freestanding portion may comprise an elbow and a straight portion for positioning the second end. The wheel bracket may be used with dual wheel assemblies and wheel covers. The wheel bracket or portions of it may be flexible and pliable to allow the wheel bracket to be adjusted to fit different wheels and allow the position of an attached object to be adjusted.

Abstract: The lamella fine cut-outs provided in profile elements of the tread surface of a tire, have three-dimensionally structured wall regions. Such wall regions restrict relative movements of the mutually facing wall regions in lateral as well as in radial direction. In such manner there are improved the travel characteristics as well as the wear characteristics like break-outs and irregular wear of such lamella tires.

Abstract: A valve for wheels for pneumatic tubeless bicycle tires. The wheel has a wellbase or drop-center rim and a valve opening in the base of the wellbase for such a valve. For simple installation of the valve, the valve body is provided on the outlet end with a cylindrical projection, the outer dimensions of which correspond to the inner dimensions of a valve opening recess, so that in the installed state the valve body has a surface which is flush with the base of the wellbase of the rim.

Abstract: A rigid valve stem cover for flexible tubeless tire type valve stems. The cover has a frustro conical shape which threadably engages the valve stem at its upper end while the bottom edge of the cover comes in contact with the stem and wheel rim area surrounding the stem and provides substantial rigidity to the stem.

Abstract: A flexible bicycle rim strip has two free ends and a securing hole near each end. The free ends insert through a rectangular valve stem hole in the rim, and are secured to adjacent spoke nipples.
