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 tire and beadlock clip system for assembly on a rim employs a tire of a type having an annular recess in each sidewall of the tire. As a result of the recessed sidewall structure, one or more beadlock clip can be directly engaged, after seating of the tire, between a corresponding abutment surface region, provided on the outer surface of the sidewall and oriented to face away from the rim lip, and an opposing surface of the rim, thereby opposing separation of the bead region from the bead seat. Preferably, the clips are resilient clips which can be snap-fit into engagement manually or with a mallet. Alternatively, a positive clamping mechanism may be provided.

The rolling assembly has a rotation axis and comprises a rim having two rim seats that is axially outwardly extended by rim flanges, one adapter and a tire having two beads. The adapter provides the connection between one of the beads and the rim and comprises an axially inner end that is adapted to be mounted on one of the rim seats, an axially outer end that is adapted to receive one of the beads and an adapter body connecting the axially inner end and the axially outer end as to form a single piece. The two rim seats of the rim have different diameters with a gap D. The adapter is mounted onto the rim seat having smaller diameter. The rim seat of the rim has a smaller diameter positions on a side intended to be inside when the rolling assembly being mounted onto a vehicle.

A rim (3) for a tire has an axis of rotation DD and a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a perpendicular plane and is situated radially on the outside with respect to said rim seat (31), characterized in that said rim flange (32) has a second portion (322) that is inclined towards the outside, is situated axially on the outside with respect to said first portion (321) and is situated at least partially radially on the outside with respect to said rim seat (31), said rim having a connecting portion (320) between said first portion (321) and said second portion (322).

A running set comprising: a tire (10) comprising two beads (20); a mounting rim (500) of which the width is greater than or equal to 55% and less than or equal to 80% of the maximum axial width of the tire inflated to its service pressure; and at least one adapter (100) which provides the connection between the mounting rim and a bead of the tire.

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.

System for attaching a tread formed as an elongated element to a tyre, such as a bicycle tyre. The system comprises at two elongated attachment members configured to be fastened along the circumference of a side of the tyre. The element and the members are provided with mutually interlocking means for engagement with each other when the element is attached to the tyre. The mutual interlocking means may be a zipper, or a hook-and-loop system, or a dual-lock system.

A rim (3) for a tire has an axis of rotation DD and a rim seat (31) extended axially towards the outside by a rim flange (32), said rim flange (32) having a first portion (321) that is oriented substantially in a perpendicular plane and is situated radially on the outside with respect to said rim seat (31), characterized in that said rim flange (32) has a second portion (322) that is inclined towards the outside, is situated axially on the outside with respect to said first portion (321) and is situated at least partially radially on the outside with respect to said rim seat (31), said rim having a connecting portion (320) between said first portion (321) and said second portion (322).

A bicycle rim has rim a pair of rim flanges that defines a tire channel. A rim strip extends across the tire channel. The rim strip includes a pair of flange bumpers configured to cover the rim flanges. The flange bumpers each define a flange channel in which one of the rim flanges is received. A pair of safety humps define corresponding tire seating sections where a tire is seated when inflated. The rim strip further includes a drop seal that seals with the beads of the tire to facilitate seating of the tire during inflation.
