I've been doing some window shopping, just looking around at various touring specific bikes as well as road bikes. Almost all of the road bikes I see list their weight, usually around 19-22 pounds, which is much lighter than my 38lb commuting bike I have been riding. But none of the touring bikes I see list their weights. Now it's not necessarily a big concern of mine, just more of a curiosity. But how much would a run-of-the-mill touring bike weigh, unloaded of course. Are they sub 30lb bikes... somewhere in the 25lb range?
