The last puncture I had was on the rim-side of the inner tube and probably was there when I bought the bike. Before that ... I think that was years ago. Most touring bikes these days also come with tyres that have a puncture-preventing layer [1]. Racing bicycles are probably not well-suited for post-apocalyptic duty. But as far as repair equipment goes, I think I think a bicycle repair kit (should be good for half a dozen punctures and they last years) and a multitool (for removing wheels and the like) should suffice for a lot, even if certain occasions need special tools. ____ [1] http://en.wikipedia.org/wiki/File:Kevlarreifen.jpg http://en.wikipedia.org/wiki/File:Kevlarreifen.jpg

Probably not, a touring or XC-type mountain bike is probably a better idea (or an hybrid, more efficient than an XC but with more "all terrains" abilities than a straight touring bike).

  Airless tires are quite a lot older than pneumatic tires, actually. But the introduction of the pneumatic tire made bicycles practical for a much wider range of people and uses.

    Yes, I meant airless tires which can actually compete with pneumatic on efficiency and comfort, obviously you could always have a back-breaking full cylinder of rubber.

      Oh? How do those work? Obviously they're physically possible (you could fill a tire with Utility Fog) but I didn't realize they were yet technically feasible.
