Bicycle head tube spacer

摘要

A spacer for positioning between a head tube of a bicycle frame and a front wheel fork of the bicycle. The spacer includes an annular body defines a center axis and extends axially between annular upper and lower spacer surfaces. A bore extends axially through the body concentrically with the center axis between a first opening in the annular upper spacer surface and a second opening in the annular lower spacer surface. The annular upper spacer surface includes a radially outer planar rim and an engagement flange disposed radially inwardly from the planar rim, the engagement flange projecting axially upwardly from the planar rim and circumscribing the opening. The planar rim and the engagement flange abut complementary surfaces on a lower mating surface of the head tube and form a seal with the head tube upon being engaged therewith.
