Since I like to go with the mountain bike in the forest, I had very frequent punctures by thorns penetrated. Because it yet but are more pleasant pursuits to patch than ever punctured bicycle inner tubes, I am well "tested" almost all on the market liquid tire sealant. None could convince me so far in its effectiveness as TT-Seal. Not only retracted thorns, but also nails and even smaller tip broken glass make absolutely no problem more! A brief hissing a low air loss is all that the "accident" displays. Then simply remove foreign bodies, possibly some air re-inflation and on we go, as if nothing had happened. Even the introduction of the sealant into the tube (to remove the valve) is quick and easy. I am absolutely thrilled with this great product, and can it with conviction SHARE!
