So many topics are covered in this thread.... I'll just stick to this one.

Probably 'cuz you're talking to bike shop salespeople and road racers. Here, you can talk to the right people You'll find both camps here, plus a lot of tourers who simply ride their preference. A major factor for me is having all the same wheel sizes for all my bikes.

Get the bike that fits. If it takes 26" wheels to do that, why is it an issue? Not trying to revive a debate, but 26" wheels with the right tires are superb for touring (as are 700c). You might come in 30 seconds behind the guy on a road bike... but if this matters you're posting on the wrong board.

You say you won't be touring for a year, so take more time to test ride and find the right fit.
