Recommendation depends on lots of variables. Are you riding alone or in a group? Are there other tub riders (for sharing of spare parts)? Often roads are in good order, as fdegrove says, but you can find quite challenging terrain if you look for uncommon/special climbs. Finally, what are your clincher options? Alu or carbon, light or heavy? When/where are you going, are you expecting rain?
Some great points, mostly solo with a few group rides as I get to know more people. Have pretty much a total Tub setup - though happy to buy some clinchers if it's the smart thing to do. I think it's fair to expect some rain, though we will be there in summer (Annecy- France). I typically ride on 23's with about 110 f and 115 psi on back.
I ride quite a bit in the (mini) alps here in Australia on tubs, and carry a sealant and spare (just incase). Sealant works a treat 80% of the time, though I have local support and friends with me should I get in trouble. This isn't something I would have straight away in the alps.
I am interested in clinchers due to these 'safety' concern, but love the ride of tubs both up and down the hills.
