comment Road bike that is gentle on body, but can go in some dirt
@zenbike good point, but the OP says 'and also go in some dirt'... I have lived in NorCal, and no, I am definitely not thinking of trails that require a mountain bike, or implying that a road bike can do what a MTB does, just that it can handle more than most think.

comment Road bike that is gentle on body, but can go in some dirt
@zenbike I am biased because most of my off-road riding has been on a road-bike. Still, I don't think a Ferrari at Moab is the proper comparison; I made an exception for 'significant obstacles, like rocks'. And I would argue that most off-road riding requires less from a bike than the Paris-Roubaix course.

An extra set of wheels, with road tires and a smaller cog-set would give a cyclocross bike pretty much the same functionality as a road bike.

comment Road bike that is gentle on body, but can go in some dirt
@zenbike nice post and good points, but I disagree with 'in no way intended for dirt'. Road bikes generally provide excellent performance off road and only become more difficult to handle than an off-road bike if going fast around a tight turn, going through mud or sand, or when there are significant obstacles, like rocks. But they are fine on most trails and fire roads. Roubaix is designed to race over large cobblestones.

@Daniel What has your experience been? Since you claim that you don't get flats, I suspect that your experience is limited, if not in duration, than in variety. I have observed many examples of what should not be done, especially when working in a bike shop.

@Daniel I did use tire when I meant tube, and I can't argue that an unopened tube might last a decade - or more with proper care. However, tubes in regular use are often no so lucky, particularly if the tube is rolled up improperly, held together with a too-tight rubber band, or exposed to weather and sweaty pockets. A ziplock bag and some baby powder will mitigate most of these abuses.

@Moab Mr Tuffy have been around for a while and are perhaps among the original liners. They have worked great for me.

@matthew -1 because your comment 'once fitted your question should be academic' is overly optimistic. This assumes that both the tire and rim strip are fitted and installed properly and that there are no pinch flats.
