Frame with standardized configuration for two-wheel bicycles.

摘要

Standardized-configuration frame (10) for two-wheel bicycle, with which a seat post (16) and a handle-bar stem (18) are coupled according to respective sliding axes (20,21), in which the axis (20) of seat post (16) sliding relatively to the frame (10), and the axis (21) of handle-bar stem (18) sliding relatively to the bicycle frame (10) are slanting in opposite directions relatively to each other, relatively to a perpendicular axis (22) to the normal plane of contact of both bicycle wheels with soil. <IMAGE>
