ABSTRACT:
The invention relates to an extremely lightweight but strong bicycle seat post that is infinitely adjustable linearly and angularly in the plane of the bicycle frame. It employs two combined fixing and adjusting bolts with the wrenching heads readily accessable on the bottom side. The linear and angular adjustments do not interact. The construction, except for the bolts, is lightweight alloy metals.
Loadbearing ability is designed to meet the needs of mountain racing and touring bicycles.
The unit can be built without recourse to unusual shapes which must be formed by casting, forging, welding or other processes requiring expensive tooling or processing; only stock pars and tubes are needed.
