Abstract: A rear hub for mountain bikes includes a hub body and a sprocket carrier rotatably provided on a hub axle. The hub body is coupled with the sprocket carrier via a freewheel mechanism. By providing a decoupling mechanism, it is possible to decouple the sprocket carrier from the hub body.

Abstract: A handlebar stem for bicycle handlebars has a stem element connected to a holding element. The holding element has a tube opening and surrounds a steer tube in the mounted state. A clamping element is arranged in the holding element. Using a clamping device, a clamping force is exerted on the clamping element for fixing the handlebar stem to the steer tube.

Abstract: A steering stop for bicycle handlebars, comprising a first stop element adapted to be fixed to the head tube of a bicycle fork, and a second stop element cooperating with the first stop element to limit the steering angle. The second stop element is adapted to be mounted to the bicycle frame, in particular to the top tube of the bicycle frame.

Abstract: A vehicle frame, in particular a mountain bike frame or a trekking bicycle frame, comprises main frame element. A rear frame is pivotably connected with the main frame element. A damping element is provided between the rear frame and the main frame element. A first connection point of the damper element is connected with the rear frame and a second connection point of the damping element is connected with the main frame element. For the purpose of changing the frame characteristics, a displacing element is provided for the displacement of the first connection point. The locking of the displacing element is done with the help of an actuator element.

Abstract: A bicycle frame, particularly a racing bicycle frame, comprises two bars. The bars are connected to a head member for connection to a saddle member. In their frame-side end region, the two bars are formed as a hollow profile. In this region, the two bars have a semicircular cross section so that a common contact face is formed.

Abstract: In a saddle tube for a bicycle frame, especially a racing bicycle frame, the bottom bracket end (22) of the saddle tube is wider in a direction transverse to the longitudinal direction (24) of the frame than in the longitudinal direction (24) of the frame. According to the invention, the saddle tube (18) has a flat portion (32) at the chain ring side.

Abstract: A bicycle handlebar, which is in particular a racing bicycle handlebar, comprises a transverse member (12) extending transversely to the driving direction (16). Said transverse member (12) is connected with two gripping members (14,21). For improving the aerodynamics, an aerodynamically configured liquid storage container (10,42) is in particular releasably connected with said transverse member (12).
