What are some of the options for touring bikes that weigh twenty pounds or so? (Plus or minus a few pounds -- bikes at the lighter side of the spectrum of touring bikes, that are light or maybe even very light, as touring bikes go, but not radically ultralight -- not sub-fourteen-pound bikes, say, but somewhere in the range of sixteen to twenty-three pounds or so, and still capable of handling light to moderate rack-mounted touring loads, not just a frame bag or handlebar bag.)
For the bikes sold and designed as touring bikes, which are among the lighter/lightest ones?
Also, which bikes are among the lighter bikes that, although not touring specific, would still be suitable or work well as tourers? (to be used for touring that is non-superultralight, self-contained, with rack-mounted loads -- or for dual use, sometimes ultralight, sometimes moderately light, or, on some trips or portions of trips, even moderately heavy at times -- bikes that could be used both ways; maybe some of the lighter, minimalist steel mountain bikes for example?)
