Adjustment device for rotationally fine adjusting angle of bicycle sections has external toothing that is provided at bicycle section, and meshes into internal toothing of intermediate ring to define predetermined set of meshing toothings

摘要

The adjustment device (1) has an intermediate ring (5) whose external toothing (6) meshes into the internal toothing (4) of a first bicycle section e.g. saddle pillar (2) to define a first set of meshing toothings. A second bicycle section e.g. saddle rail support (8) has an external toothing (10) which meshes into internal toothing (7) of intermediate ring to define a second set of meshing toothings. The second set of meshing toothings has second minimum rotation angle different from first minimum rotation angle of the first set of meshing toothings.
