A pull shock damper for a bicycle comprising a spring device and a damper device, the spring device comprising a positive spring and a gas-operated negative chamber. The damper device comprises a first oil chamber and a second oil chamber connected therewith. The negative chamber abuts the first oil chamber via a piston. A tubular structure extends from the piston through the negative chamber interior up to the end of the negative chamber. The piston rod of the piston extends through the first oil chamber to the exterior.

Damper for a bicycle

A spring system in particular for bicycles includes a gas suspension spring with adjustable progression and a housing element for movably receiving the suspension piston of the gas suspension spring. The gas suspension spring has a spring volume including a first spring chamber and at least a second spring chamber separated from one another by a partitioning member. The first spring chamber is arranged within the housing element and the second spring chamber extends internal of the housing portion consecutive to the housing element.

Spring system for bicycles

An axle system, and a two-wheeler component with a first dropout and a second dropout and an axle system with an axle for receiving a wheel of a two-wheeler, wherein a clamping mechanism with a tightening device and an end device is provided and equipped to clampingly attach the axle received at the dropouts between the tightening device and the end device. The clamping force is independent of a possibly possible rotary movement of the axle.

Axle system for a two-wheeled vehicle

A suspension fork for a bicycle includes at least one stanchion tube and at least one slider tube interacting therewith and a wheel receiving space adjacent thereto. The suspension fork includes a damper system with a damper chamber divided into a first chamber and a second chamber by a movable piston. The suspension fork further includes a damping device for the rebound stage and a damping device for the compression stage are provided. A shut-off valve is provided for selectively locking the rebound stage. The damper chamber comprises a connecting duct with a flow damper that connects the second chamber with the first chamber when the stanchion tube and the slider tube interacting therewith are compressed more than a predefined distance such that in the case of a forceful compression and with the shut-off valve of the rebound stage activated, slow decompression is allowed up to a damper position as defined by the predetermined distance.

Suspension fork for a bicycle

A bicycle component with a wheel mount at which a wheel with a hub can be received, with the wheel mount including two tube components provided with a mounting device at each of its end portions. At the mounting device of at least one tube component a bushing device is arranged to be exchangeable and to be suitable and intended to receive and support a hub.

Bicycle component

A slider tube unit for a suspension fork of a bicycle, including two spaced-apart slider tubes and a wheel receiving space in-between, and at least one connector bracket connecting the two slider tubes above the wheel receiving space. The connector bracket includes a connector body which in its longitudinal extension from the one slider tube to the other slider tube is configured hollow wherein the connector body consists of an open basic profile and a reinforcing device closing the opening of the basic profile.

Slider tube unit for a suspension fork

A suspension fork for a bicycle includes at least one stanchion tube and at least one slider tube interacting therewith and a wheel receiving space, and a damper system. The damper system includes a damper chamber divided into a first chamber and a second chamber by a movable piston and a damping device for rebound damping and a damping device for compression damping. The damper system is disposed at the stanchion tube, the damping device for rebound damping and the damping device for compression damping are disposed above the movable piston.

A spring system in particular for bicycles includes a gas suspension spring with adjustable progression and a housing element for movably receiving the suspension piston of the gas suspension spring. The gas suspension spring includes a spring volume including a first spring chamber and at least a second spring chamber separated from one another by a partitioning member. The first spring chamber is arranged within the housing element and the second spring chamber extends internal of the housing portion consecutive to the housing element. One single adjustment element allows adjustment of both the damping system and the spring characteristics.
