An adapter for a rolling assembly having an axis of rotation (YY′) includes an axially inner end connected to a rim, an axially outer end including an outer reinforcing element and intended to come into contact, via a substantially radial axially inner face, or bearing face, with a bead, a body connecting the axially outer end to the axially inner end so as to form a single piece, including at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and including a substantially axial adapter seat intended to come into contact with a bead. The outer reinforcing element (15) is completely axially on the outside of the bearing face (21), and the outer reinforcing element (15) is a substantially annular structure, referred to as a bead wire, of substantially polygonal section, including at least two first layers of composite and/or metallic material, and at least two second layers of rubber compound, the first and second layers being arranged mutually parallel and in alternation with each other and parallel to the axis YY′.

Provided is a sealant material composition that makes it possible to ensure good sealing properties and to suppress sealant flow due to traveling. As a sealant material composition forming a sealant layer disposed on an inner surface of a pneumatic tire, a sealant material composition comprising from 1 part by mass to 40 parts by mass of an organic peroxide and from 0.1 parts by mass to 40 parts by mass of a crosslinking agent, being blended, per 100 parts by mass of a rubber component containing a chlorinated butyl rubber, is used.

Provided is a pneumatic tire having sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by applying a sealant to the inner periphery of a tire from which mold release agents have been removed.

Adapter providing the connection between one tire bead and the rim. An axially inner end of the adapter is mounted on the rim seat, an axially outer end is mounted on the rim seat, a body connects said outer end to said inner end, a substantially cylindrical adapter seat receives one of said beads, and an adapter bearing face is substantially contained in a plane perpendicular to the axis. The reinforcer element of the axially outer end is entirely situated axially outside the bearing face. The body comprises, opposite the adapter seat, an annular seat protuberance, said protuberance comprising at least one rubber composition.

A hubcap for a wheel with a floating tire seat, the wheel having a rim comprising a tire seat extended axially outwards by a flange, the tire seat being radially floating, comprises a central edge and an exterior periphery, in which the central edge comprises fixing elements for attaching to the rigid part of the wheel and in which the central edge is connected to the exterior periphery by an intermediate sector that is deformable so that the exterior periphery can be moved at least radially inwards with respect to the central edge.

An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.
