Just going back over the thread and saw this. You mentiod a "folding" Turbo Armadillo. Doesn't that mean it has a kevlar bead? When I looked on the Specialized website, the turbo armadillo said it had a wire bead and a 700x23 weighed 385 grams so I'm curious about this discrepancy, especially since a kevlar bead should be easier to take off and put on.

Also found a weight for the Mr Tuffy liners: 113 grams. However, I'm not sure if that is the weight of one, or two (as they come two in a pack). Also I'm not sure if that is for the size strip I have.

My present tires are listed as 250 grams. If you add in the 113 (assuming that is right for each), we total 363 plus the tube.

The Turbo armadillo closest to my present size (mine are 25c and the turbo would be 26c) would be 437 grams. But dropping down to a 23c would only be that 385 - just 22 grams more than what I ride now.

I see comments about using ultralight tubes with the Armadillos. I don't know much about them - I have always just bought whatever I found in the store.

as far as i can tell few, if any, people have come back to the shop complaining of a flat after we installed their liners.

if you do want the ultimate in flat protection, i'd recommend against using ultralight tubes with your armadillos. in fact, i'd probably recommend using a tube that's meant for a bigger tire, say 700x38. the tube will be thicker, thus a little more flat resistant.

i do use ultralight tubes, but only on my race wheels which aren't ridden anywhere but the track. as far as my own every day wheels, i use whatever tires are on sale, mr tuffys, and regular kenda tubes.

Well, I wouldn't be concerned about "a" flat. I know nothing is perfect, but getting them a lot is a real hassle. It would be nice to go 1000 miles or so between flats.
