Abstract:
The present invention provides a compound, system, and method for retrofitting and converting standard bicycle rims and tires having tubes to be tubeless. Standard tube tires are retrofitted by installing either rim tape or a rim strip with integral valve stem around the inner channel of the rim, mounting the first bead of the tire, injecting a liquid sealing compound into the tire cavity, finishing mounting the tire, inflating, and installing the tire on a bicycle. The sealing compound may additionally contain propylene glycol or an aggregate material to encourage the sealing of the tires as punctures occur when the tire system is placed into use.
Abstract:
A tyre for a vehicle wheel includes a carcass structure, a belt structure, a tread band, and at least one pair of sidewalls. The carcass structure includes at least one circumferential centering ridge jutting out from a crown portion of the carcass structure. Each bead of the tyre includes a rest surface defining, in a direction away from an equatorial plane of the tyre, a profile converging toward the rotation axis of the tyre. A rim for a tyre includes a base body and two seats. Each seat defines an abutment surface facing radially away from a rotation axis of the rim and includes a frustoconical configuration converging away from a median diametrical plane of the rim. The base body further includes at least two opposite radial shoulders disposed to abut against the at least one centering ridge. A vehicle wheel, including the tyre and the rim, is also disclosed.
