The Hutchinson Fast Air is the only sealant Hutchinson recommends with their tubeless tires. It is a latex-based sealant that comes in a 75ml CO2 canister. It both inflates tires from 0 psi and seals from punctures. It can be applied before initial inflation or on a ride after a tire has gone flat (we recommend inspecting tire for cuts before using Fast Air). It can inflate a 26x2. 0 MTB tire to 30psi or a 700x23 road tire to 80psi in less than 90 seconds. In both cases, the pressure is a bit low, but should be enough to ride home on. We recommend being careful when applying. We've found that having the can off-center results in sealant squirting out onto the rim and leaving a latex hairball.
