Abstract: A control device for bicycles has a main body for attachment to a bicycle handlebar and at least one actuation arm for controlling a brake and/or a derailleur of the bicycle. The at least one actuation arm has a first portion having a finger actuation area and a second portion for controlling the brake and/or the derailleur, said first portion and said second portion being distinct bodies fixable to each other. The first portion can therefore be replaced without disassembling the control device, with an identical one when it breaks, wears down or is damaged, or else with a different one in terms of the constituent material, color or similar, to satisfy the different preferences of the cyclist, or even different in shape and/or size, in particular in curvature and/or length, so that the control device is adaptable to cyclists with hands that depart from average size. To this purpose, a same first portion can also be fixable in at least two different positions with respect to the second portion.

Abstract: A rim for a spoked bicycle wheel is disclosed that has a change of radial section of the side walls. Through changes of symmetry/asymmetry with respect to a middle plane and/or changes of radial extent, it is possible to improve the performance of the rim in terms of balance, camber angles and/or strength. Preferably, the radial section is variable, still of constant area along the circumference, apart from apertures for the attachment of spokes and possible openings for the passage of nipples. A process for manufacturing a rim for a bicycle wheel is also described, comprising hydroforming a tubular extruded piece to locally change the section of the side walls.

The hardened plastic matrix retains an insert within the body of the crank lever. The crank lever can also include a hollow cross section along a portion thereof. The reinforcing fibres can also be randomly arranged within the thermosetting material matrix.

Abstract: A bicycle bottom bracket assembly has a shaft having a longitudinal axis extending along a predetermined direction and a first and second end portion. A first bearing has an inner ring inserted on the shaft in a position adjacent to the first end portion and an outer ring is coupled with a first adapter adapted to be associated with a first end of a housing box of the bottom bracket assembly in a bicycle frame. A second bearing has an inner ring inserted on the shaft adjacent to the second end portion and an outer ring coupled with a second adapter is associated with a second end of the housing box. The assembly further includes first locking means of the inner rings of the first and second bearings acting on the inner rings to prevent the movement of the inner rings in both ways of the predetermined direction.

Abstract: The invention relates to a bicycle brake control device, comprising a support body to be fixed to a handle bar and suitable to receive an end length of a traction cable according to a line, and a brake lever pivoted on the support body for actuating the brake through the traction cable when it is pulled towards the handle bar, the brake lever having a first actuation area at one end, wherein the pivot of the brake lever is arranged at a position which is not intermediate between the intersection of the line with the brake lever, and the first actuation area of the brake lever. Through such a configuration, the length of the brake lever on the side of the first actuation area, i.e. on the useful side of the brake lever, increases.

Abstract: A bottom bracket assembly of a bicycle comprises two cranks, an axle integral in rotation with the cranks, and two bearings for the rotatable support of the assembly with respect to a box of the frame of the bicycle; each of the bearings is arranged inside the thickness of one of the respective cranks. In this way, the weight of the cyclist acting on a crank transfers directly onto the corresponding bearing, without any bending stress being generated on the axle of the bottom bracket.
