Abstract: A releasably locking device, and clamping element for such a device, secures a bicycle component to a bicycle frame. The device has a traction rod associated with a rotation cam extending in a housing. The rotation of the cam is driven by a lever-operated manual actuation system between a clamping operating position and a release position. The rotation cam has two ends that can be commanded into synchronous rotation through said lever-operated manual actuation system.

Abstract: The integrated control device (1) for driving the control cable (20) of the derailleur and the brake cable (16) of a bicycle is provided. The device having a support body (4) connectable to the handlebar (2) and that can be gripped by the cyclist's hand, a cable-winding bush (19) about which the control cable (20) of the derailleur is wound/unwound and a first lever (9) rotatable with respect to the support body (4) about a first axis (X1) for actuating the brake cable (16) and rotatable about a second axis (X2) to drive the cable-winding bush (19) into rotation in a first direction of rotation (R2). An indexing mechanism (12) connected to the first lever (9) cooperates with the cable-winding bush (19) to define predetermined angular positions therefor. The support body (4) having a recess (25) for the passage of the control cable (20) of the derailleur.

Abstract: A bicycle bottom bracket assembly that reduces the accumulation of dirt and/or corrosive substances inside the shaft extending between the crank arms of the assembly. The bottom bracket assembly includes a shaft having a through-cavity that extends along its longitudinal direction; a crank arm is associated with each end portion of the shaft, and the through-cavity extends unobstructed through the crank arms and the shaft.

Abstract: A sprocket assembly mounted to a hub has at least eleven sprockets. The hub is able to rotate about a rotation axis and has a plurality of spoke attachment seats and a fastening portion to a frame of the bicycle. On the hub a predetermined axial distance is defined between a plane, substantially perpendicular to the rotation axis, comprising the points of the spoke attachment seats closest to the freewheel body and a plane, substantially perpendicular to the rotation axis and defined in the fastening portion to the frame, comprising the attachment points to the frame closest to the freewheel body. All of the sprockets of the sprocket assembly, when associated with the freewheel body, have an overall axial width that is lower than or equal to the predetermined axial distance. The chain has a maximum thickness between 4.6 mm and 5.8 mm.
