Patent ID: 8398107

Claim:
A bicycle angle adjustment device for rotationally adjusting a first bicycle part in relation to a second bicycle part, wherein the first bicycle part is provided with a hole with an internal toothing; an intermediate ring is provided with an external and an internal toothing, wherein the external toothing of the intermediate ring, when mounted, meshes into the internal toothing of the first bicycle part, in such a way that a first set of meshing toothings is formed; and the second bicycle part is provided with an external toothing, which, when mounted, meshes into the internal toothing of the intermediate ring, in such a way that a second set of meshing toothings is formed; wherein the first set of toothings has a first minimum angular rotation and the second set of toothings has a second minimum angular rotation; wherein the first minimum angular rotation differs from the second minimum angular rotation; wherein the device is for rotationally fine-adjusting the first bicycle part in relation to the second bicycle part with a few degrees; wherein the difference between the first and the second minimum angular rotation is 0.05° at the least and 20° at the most; wherein the first bicycle part is a saddle pillar with a continuous hole extending transversally in relation to the longitudinal direction wherein the hole is provided with an internal toothing; wherein the external toothing of the intermediate ring, when mounted, meshes into the internal toothing of the saddle pillar, in such a way that a first set of meshing toothings is formed and wherein furthermore a saddle rail support is provided with an external toothing; and wherein, when mounted, the toothing of the saddle rail support meshes into the internal toothing of the intermediate ring, in such a way that a second set of meshing toothings is formed.
