It is tested to 180mph and gives you the security of never getting a puncture and getting the full life out of the tyre.

Although I don't have it in my current bikes (I will have soon) I have used it in the past to repair a puncture and it is brilliant.

Its only a stupid question if you know the answer brother!

Ahh, maybe not the same but I used something similar to repair a puncture on one of my old street bikes... After a week or so I removed the tire to change it and all the white goo stuff that was supposed stick to the tire inside it and repair it was just loose inside (it still fixed the puncture though), don't know if it was the temperatures at that time that did it. We almost 30 Celsius degrees then or then again maybe it is supposed to work like that
