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.
A hub, in particular for bicycles having a hub shell and two bearings received therein on bearing seats for rotatably supporting relative to a through axle, wherein the two bearings are retained at a defined axial distance by means of a sleeve. A radial spacer device is provided to reduce radial play of the sleeve in the hub shell and to facilitate inserting the through axle.
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.
A method of producing a bicycle rim including, positioning a first quantity of woven fiber strips having a first width and a first length and a second quantity of strips of said woven fibers having a shape different from the first shape to form a first laminated band from the first quantity and the second quantity of strips. A second narrower laminated band is produced. The first band is re-shaped to a V-shaped band before the first band is inserted along the periphery of a mold interior. A core is positioned on the first band and the second band is positioned on the first band. Rim well rings are positioned from outside on the second band, to abut the sides of the second band. A spreader ring is inserted between the rings to join the material near the upper rim flanks and the rim flanges.
A hub for bicycles, having an axle and a shell, two bearing units arranged substantially between the hub axle and the hub shell, and a rotor rotatably supported relative to the hub axle for receiving a sprocket the rotor, and a freewheel having two toothed disc units with biased tooth faces for transmitting the drive torque from the rotor to the hub shell. The two toothed disc units are disposed around the hub axle upon assembly, they are, at idle, disposed transverse to the hub axle. At least one toothed disc unit includes a toothed disc having a hole, a radial wall and an axial toothed wall, wherein an inner diameter of the hole is smaller at the axial wall than an inner dimension in the radial wall to form a receiving space at the toothed disc between the clear inner diameter of the axial wall and the radial wall.
A quick release for bicycles comprising a pull rod extending in the axial direction, an end element at a first end of the pull rod, a clamping element at the second end of the pull rod, and a tensioning device for tensioning the clamping element. The tensioning device comprises a lever for applying the clamping force and a tensioning sleeve with a transmitter portion for transmitting the clamping force to an engaging portion of the clamping element. The lever is positioned to be movable relative to the clamping element in the axial direction of the pull rod and against the biasing force of a biasing spring is movable outwardly in the axial direction of the pull rod from an engaged position to a turn position. In the turn position an angular position of the lever can be set independently of the state of tensioning.
