Abstract: A protective tire liner is positioned between the bicycle inner tube and the bicycle outer tire of a bicycle wheel. The tire liner includes a puncture-resistant flexible strip to protect the inner tube from puncture damage, and at least one covering layer on the puncture-resistant flexible strip to cover at least the side edges thereof. The puncture-resistant strip has a relatively abrasive surface especially at side edges thereof so as to be capable of abrading the inner tube upon relative motion. Accordingly, the covering layer prevents abrading of the inner tube which would otherwise occur. The protective liner protects the inner tube from puncture damage, such as from thorns, as are commonly encountered when mountain biking. In one embodiment, the at least one covering layer comprises a flexible plastic strip spirally wound about the puncture-resistant flexible strip.

Abstract: A bicycle seat post and clamp includes a tube and a flange connected to an end thereof with the flange comprising a pair of opposing ears extending longitudinally outwardly from the tube and having an upper surface defining a laterally extending recess for receiving a lower clamp member. A lower clamp member preferably includes a lower clamp body portion having a lower surface defining a laterally extending partial cylindrical shape received in the recess of the flange, and a pair of lower rail channel defining portions connected to respective opposing longitudinally extending sides of the lower clamp body portion. Each of the lower rail channel defining portions preferably includes a pair of cantilevered rail support portions extending outwardly from the lower clamp body portion. The upper clamp member preferably includes an upper clamp body portion and a pair of upper rail channel defining portions connected to respective opposite longitudinally extending sides of the upper clamp body portion.
