1. A bicycle seat post assembly comprising:
a. a base assembly connectable to a bicycle and having an outer tube having an upper end, a lower end spaced apart from the upper end along an assembly axis and a collar secured on the upper end;
b. an extension assembly comprising an inner tube having an upper end for connecting to a bicycle seat, a lower end that is telescopically receivable in the outer tube and an inner contact member positioned toward the lower end of the inner tube and slidable with the inner tube within the outer tube, wherein the inner tube is movable relative to the outer tube between a retracted position in which the lower end of the inner tube is disposed toward the lower end of the outer tube and an extended position in which the inner tube is spaced from the lower end of the outer tube by an extended distance; and
c. a positioning assembly comprising one or more shims with a plurality of axially spaced apart lower surfaces that are each configured to contact an upper surface of the inner contact member at a respective shim length, the one or more shims being retained within the base assembly when the collar is secured on the upper end so that when the inner tube is moving from the retracted position toward the extended position the inner contact member engages one of the lower surfaces to limit the axial extension of the inner tube at an intermediate position in which the lower end of the inner tube is spaced from the lower end of the outer tube by an intermediate distance that is less than the extended distance.
