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 includes 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 and/or the spline unit can be moved relative to the guiding groove in the peripheral direction.

Bicycle component with an adjustable seat post device

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.

A damper device for a bicycle having a housing extending in the axial direction and disposed therein, a chamber which forms a chamber volume that is sealed outwardly. The chamber volume extends in the axial direction from a first end to a second end. In the axial direction, at least one adjustment member is rotatably disposed between the ends of the chamber volume. The adjustment member is configured as an annular member and is rotatably received at the housing and surrounds at least part of the housing. By way of movement of the adjustment member, at least one operational setting of the damper device is changeable by means of a mechanical transmitting device.

Damper device for bicycles

A quick release mechanism for at least partially muscle-powered two-wheeled vehicles such as bicycles having a through axle extending in the axial direction, a clamping device at a first end of the through axle and a fastener at the second end of the through axle and with a clamping mechanism for clamping the clamping device. The clamping device includes an engaging section for applying a clamping force from the clamping mechanism to the clamping device and a clamping section with an annular pressure area for clamping. The clamping device has a tubular mounting section extending from the clamping section in the direction of the second end of the through axle and to which the through axle is attached.
