I have seen that, not a bad idea. But it probably sprung from the old method of simply ziptying the area with a hole. Basically if you get a flat on the trail you do it like they say, lay the bike over pull the tube, find the holes and zip tie some zip ties on ether side of the hole and put it back in. I hear this works pretty good and at the worst you have to do is stop every 5-10 miles and put some more air in. Some friends were talking about this trail tube and we decided you still need to bring a tube, the spoons and an inflating device so you really are not saving much.
They were around 20+ years ago. Can't remember what the problems with them were. Now it's comming back? Later George
I have never seen this before, I can understand if you were racing at the pointy end of the field, but when you are out trail riding with your mates, I think it would be ok Kel
