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.

Provided is a coupling unit for coupling a tire to a rim, the coupling unit including an upper surface, a lower surface, and side surfaces, in which a maximum length of the coupling unit is larger than a distance between both hooks of the rim, the side surfaces include sliding areas that are slidable with respect to the hooks of the rim such that the coupling unit is easily inserted into the rim while the coupling unit is being inserted into the rim, and in a state in which the coupling unit is completely inserted into the rim, at least a part of the upper surface is in surface contact with lower surfaces of the hooks to prevent the coupling unit from being separated from the rim.

Rolling assembly comprising tire P, rim J, adapter connecting a bead and the rim. The adapter has axially outer (9) and inner (10) ends mounted on rim seat (7) having respective outer (16) and inner (20) reinforcers. Body (11) connects the outer (9) and inner (10) ends forming a single piece, an adapter seat (18) receives a bead and is situated at end (9), an adapter bearing face (21) in a plane perpendicular to the rotation axis, and situated on the axially inner face of outer end (9). Reinforcer (20) of end (9) is axially outside bearing face (21). The body comprises, opposite adapter seat (14), annular seat reinforcer (19) and the adapter comprises conductive strip (22) positioned over all or part of the circumferential perimeter of said adapter and along a complete path extending from adapter seat (14) to rim flange (8).

A system and method for a tubeless tire insert. The present invention includes an annular body having shock absorbing characteristics. A positioning system configured to vary a mean inner diameter of the insert is also included. The insert has a mean inner diameter X when the tire is being installed on the rim, and the insert has a mean inner diameter Y when the tire is installed on the rim, where X is greater than Y.
