I'm not sure why this tube is easier to manipulate than others, but it just is. Seems like they would all be the same, but this one packs into my little seat pack like a charm.
I use them in my winter wheels with Conti Gatorskins. No fuss, no muss. Do the job. I have bought about 6 or 7 of these tubes over the last few years. They seem to be consistent quality out of the box.
These are good general riding tubes. I live in the Denver area and we are plagued with goat head thorns. They will penetrate anything. They don't stop flats but they are decent low cost tubes that hold air for days without requiring a top off. They don't have removable valves.
A SUPER value for the $...The only reason I didn't rate at 5 stars is due to the fact that it will wear out..it isn't bullet proof..but that being stated..for the money..tough to beat.
