Tire Sealants: Do They Really Work?
After having a flat today, I noticed at the store that Schwinn sells tubes with sealants already in them, and claim to self seal puntures up to 1/8 inch. Do they really work? These tubes are at least twich as heavy as the standard tubes. The shelves for the standard tubes were empty, while the self-sealing tube (which cost twice as much) shelves were full of stock.
I've seen many people complain about "Fix-a-Flat" sealants for automobile tires.
How about the Schwinn canister sealant? Does it pay to carry it, or is this stuff hype as well?
