Patent attributes
A bicycle component for an at least partially muscle-powered bicycle, including a seat post device adjustable between two positions, with two support members telescopically movable relative to one another in the axial direction namely, a first support member and a second support member. The bicycle component has an anti-twist protection with a clamping element that non-rotatably couples the support members together, and which is displaceably received in a guiding groove, so that rotational movement of the first support member relative to the second support member can be at least partially blocked. The anti-twist protection includes a spline device with a spline unit that can be pressed against the clamping element in the axial direction. By pressing the clamping element and the spline unit together, the clamping element can be moved relative to the guiding groove transverse to the axial direction.
