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.
