摘要： One aspect of the invention relates to a diagnosis method for a bicycle hydraulic braking system (1) of the disc type, in particular of a master cylinder assembly (7) thereof, which comprises:
a) providing a master cylinder assembly (7) comprising a cylinder (8), a piston (9) movable by reciprocating motion inside the cylinder (8) against the action of a return spring (10), as well as a hydraulic tank (20) comprising a bottom (23), a ceiling (22), and a membrane (25) dividing the tank (20) in a variable volume filled chamber (26) and a complementarily variable volume empty chamber (27), said tank (20) being fluidically connected to the cylinder (8) through at least one main passage (21) in said bottom (23),
b) providing a meter device (40) of the distance of the membrane (25) from the ceiling (22) of the tank (20),
c) inserting a hydraulic fluid (5) in the master cylinder assembly (7),
d) moving the piston (9) by reciprocating motion inside the cylinder (8),

摘要： This bicycle wheel comprises a rim (11) connected to a hub (12) by a plurality of spokes (13), wherein at least one of the spokes (13) is anchored to the rim (11) through a nipple (20) having a stem (21) inserted in a hole (17) in a bridge (16) of the rim (11) and facing towards the hub (12) and an enlarged head (22) hooked to the bridge (16). An abutment interface (30) between the head (22) of the nipple (20) and the bridge (16) of the rim (11) comprises:
- a first washer (31), with a radially inner first face (32) abutting on the bridge (16) and a radially outer second face (33),
- a second washer (41), with a radially inner first face (42) abutting on the second face (33) of the first washer (31) and a radially outer second face (43) abutting on the head (22) of the nipple (20).
The faces (32, 33, 42, 43) of the washers (31, 41) are shaped so as to allow the washers (31, 41) to make adjustment movements both with respect to each other and with respect to the nipple (20), during an initial step of the fixing operation of the spoke (13) to the rim (11), and vice-versa so as to prevent the washers (31, 41) from making any adjustment movement both with respect to one another and with respect to the nipple (20), during a subsequent fixing step of the spoke (13) to the rim (11) in which the nipple (20) has tension applied to it through the spoke (13).

摘要： The bicycle rim, made with a plurality of layered structures of composite material, each formed by one or more layers of structural fibres incorporated in a polymeric material, comprises a radially outer peripheral channel (11) comprising an upper bridge (12) extending between two opposite wings (13, 14) for holding a tyre. The peripheral channel comprises an inner layered structure (31), extending from one of the wings up to the other, and at least one wrapping layered structure (32), wound on the inner layered structure at least at the end (15, 16) of the wings, the inner layered structure and the wrapping layered structure being included in said plurality of layered structures.
The wrapping layered structure on the end of the wings not only provides a reinforcement to the wings themselves, but also protects the ends of the wings with respect to possible phenomena of delamination, preventing the occurrence thereof also in the case of traumatic events, like for example the bursting of a tyre or a particularly heavy impact of the rim on a rigid obstacle.
