A seat post for a bicycle comprises a post body having a first end shaped to be connected to a bicycle frame, a second end shaped to be connected to a saddle, at least two longitudinal portions meshing with each other and slidable relative to one another along a longitudinal extension, and a fixing apparatus by which the two longitudinal portions can be fixed to one another in a settable relative position, the fixing apparatus being influenced to selectively fix and unfix by a radio signal.

Electronically controlled suspension system, method for controlling a suspension system and computer program

An electronically controlled suspension system for a bicycle includes at least one spring element between first and second parts the bicycle, both parts being movably interconnected. At least one parameter of the spring element is modified. At least one actuator influences the spring element to modify the at least one parameter. An electronic module produces a control signal for the at least one actuator. A control device is influenced by the control signal produced by the electronic module. The control device is connected to at least one of the electronic module and the actuator through a radio signal. A corresponding method controls the suspension system for the bicycle and a computer program executes the method.

A lower leg () for a suspension fork has two tubes () with, in each case, a receptacle device () for receiving a stanchion tube displaceably mounted in the receptacle device. Two stabilizers () connect those end regions of the two tubes which are opposite the dropouts of the tubes to one another. The lower leg () has a stiffening member () which connects the two stabilizers to one another.

A brake disk for a disk brake, in particular, for motor cycles or bicycles, includes a brake band of a first material which has a high heat resistance and an inner part () of a second material which has a lower density than the first material. The brake band and the inner part () each have a plurality of extensions, which in each case are arranged in pairs bordering one another. A plurality of connecting elements connect the brake band () to the inner part () by being received in recesses () formed in the extensions. Thus, a divided brake disk has little deformation or wear in the region of the connection between the brake band and the inner part in combination with a low weight. Specifically, the recess () is formed in such a way that the connecting line () between the ends of the recess () is at an angle &#x3b1; of from 15 to 85&#xb0; to the tangential direction ().
