Rear shock absorber for bicycles

摘要

A shock absorber including a top tube-shaped body and a bottom tube-shaped body connected telescopically, wherein the bottom body has an oil cavity disposed above a gas cavity, the cavities being separated by a floating piston. An inside ram has a bottom portion, disposed in the oil cavity, and a center rod, upwardly extending from the bottom portion and fastened to the top body, so that movement of the top body is accompanied by the axial movement of the inside ram within the oil cavity. The shock absorber further includes a mechanical blocking system that optionally prevents relative axial movement between the top body and the bottom body.
