My predictably disappointing experiment with converting to tubeless tires left me with little confidence in bicycle marketing, but also a bottle of Stan's sealant. The reviews and videos I have seen have been extremely positive when it comes to flat prevention. It's an important part of cycling because as you grow ahh..."more mature" in the sport you will develop sport specific allergies. Flat tires make me break out in embarrassing obscenities. If a couple ounces of this obnoxious looking chemical can prevent these outbreaks then it's worth the experiment.
After filling the syringe with the prescribed amount of milky stuff, release the clamp and use the plunger to force all the stuff into the tube. Once that's done rotate the tire so the valve is not at the bottom of rotation, wipe off any excess stuff and screw the valve stem back in place. I usually need to give the valve stem a little tweak with some pliers to make sure it's seated. I did 5 bikes in a little over 30 minutes. Now if this stuff works I will probably not know until I wear out a tire. I suppose any small puncture will be sealed at the tube and I won't see the stuff come out as shown in those dramatic You Tube videos. When I replace a tire I expect to see little white smears on the tube and inner casing, but we'll just have to wait and see...I'm so excited.
