I bought a can of Vittoria Pit Stop in preparation for an upcoming race. The guy at by LBS told me to let the sealant fill the tire,
remove the cannister, spin the tire,
then re-insert the cannister to inflate the tire. Has anyone tried this?
Do I need to wait a minute or two to let the sealant "set" before inflating the tire?
(I've read though some of the threads regarding Vittoria Pit Stop. It seems to procedure is to completely empty the contents of the cannister before removing it and then rotating the tire.)
Hi--I used this after flatting at mile 50 of a half IM. It workedwell. The verbiage at
http://www.bikesportmichigan.com/...toria-Pit-Stop.shtml includes these examples:
"The idea behind Vittoria Pit Stop is that you don’t have to change a flat tire. You simply inject the gas/foam mixture into the tire when you flat and get back on your bike....You just shoot the stuff in the tire and go,"
and again,
"When you have a flat tire you simply open your valve stem, press the nozzle on the Vittoria Pit Stop canister onto your valve stem and press toward the tire to release the compressed gas and the liquid foam sealant. Both substances shoot into the tire under pressure.... It seals the hole and inflates the tire
simultaneously." (emphasis added)
Ideally, after discharging the cannister into the tire, there is no
need for further inflation.
The icons on the can, though, suggest additional action *may* be needed,
though not with the can:
1. a nail is pulled out of the tire.
2. a finger insures the valve is open.
3. the cap is removed form the cannister.
4. the cannister is pressed over the valve at a right angle.
5. a handkerchief wipes off a bit of foam from the valve.
6. the tire is rotated.
7. a hand holds the tire--probably checking it for sufficient inflation?
8. a
portable bicycle pump hovers near the tire; an unspecified gauge--
with number like "10," "11," "12," "1," and "2" appears at the
top of the diagram; a gray band suggests elapsed time. the
intended meaning may be, "see? less than a minute."
I take all that to mean, "if the cannister doesn't fill the tire up to
sufficient pressure, you may need to inflate it a bit more." From the
web site above and my own experience x1, the inflation was sufficient.
In a recently resurrected post from last fall about IM Wisconsin, though,
TDemerly lists his on-the-bike equipment and doesn't seem to be using the
pit stop, at least at that particular event.
I see nothing in any of this suggesting that you routinely need
to--or, if used properly, even can--apply the cannister x2, though,
as you say your LBS person recommends.
