STAYFILL is a proprietary gas blend that
keeps bike tires inflated for over a year. The actual gas mixture is a trade
secret. But we can tell you that STAYFILL’s molecules are 2-3 times
larger than CO2 or air molecules. STAYFILL’s larger molecules do not
pass through tire walls like CO2 or air molecules.
should I use STAYFILL?
STAYFILL makes sure your bike is ready
to go when you are. No more pumping tires when you or your kids want to go
on a bike ride. STAYFILL eliminates the hassle and frustration of pumping
tires and offers the convenience of ready-to-go bikes.
STAYFILL be used with CO2 or air?
STAYFILL can be used with CO2 or air.
However, concentrations in excess of 14 psig may result in some CO2 or air
leaking out and require a top off with STAYFILL.
STAYFILL safe to use?
STAYFILL is non-toxic, non-flammable,
and non-ozone depleting. However, STAYFILL is packaged under pressure and
can be dangerous if not handled properly.
I take STAYFILL on airplanes?
The FAA and TSA prohibit the transportation
of compressed gases in carry-on luggage. But you can pack it in checked luggage.
Or, if you have an event where you will need STAYFILL, contact us to either
have STAYFILL waiting for you at your destination or for the name of the
nearest STAYFILL dealer.
STAYFILL damage my tires?
STAYFILL is inert and will not harm your
does temperature affect STAYFILL in my tires?
STAYFILL, like all gases, changes its
pressure with changes in temperature. When temperatures drop, the pressure
will drop. This means you may have to top off your tires with more STAYFILL
when outside temperatures drop. Conversely, if you top off or fill your tires
when it is cold, you may have to let some STAYFILL out of the tires when
it gets warm again to get back to the optimum pressure.
will STAYFILL perform in latex based tires?
Great. STAYFILL will stay where it is
supposed to -- in your tires. The thinner latex tire walls are perfect for
STAYFILL. While tires filled with CO2 or air will see extremely high leak
rates, STAYFILL will not pass through the latex tire walls.
much extra weight will STAYFILL add to my bike?
STAYFILL is heavier than CO2 or air but
the actual amount will depend on the size of the tube and fill pressures.
In our tests using high-pressure road tires, STAYFILL added approximately
3 ounces more than CO2 when filling both tires. For the weight conscious
this may be unacceptable, but for most of us, STAYFILL weighs less than one
of those energy bars you might take on a ride.
else can STAYFILL be used?
STAYFILL can be used in basketballs, footballs,
soccer balls, inflatable pool toys, baby joggers, bicycle air struts, wheelchairs,
ATVs, and more. Please write us and let us know about other uses for STAYFILL.
We'd love to hear about it.
