Adjustable telescoping system for a bicycle

摘要

In a preferred embodiment, a light weight telescope assembly for bicycles that is readily adjustable by riders in the field and that provides smooth action of the suspension system. This telescope assembly contains roller bearings to reduce stiction and prevent torsional losses. The adjustment mechanism includes an adjustable outer race shim composed of two oppositely tapered races moving longitudinally in relation to each other, thereby causing their combined thickness to expand or contract thus allowing the bearing pre-load to be adjustable. Integral with this adjustable pre-load mechanism is a bayonet-style collar whose design enables bearing pre-load adjustment from a position that is readily accessible by consumers. In addition, this collar enables greater geometric latitude on the shape of the inner tube, thereby enabling significant strengthening of the telescoping assembly using light weight materials and lower cost manufacturing processes that hitherto have been unachievable.
