you can tour on whatever you like. I know people come here looking for advice, but I cannot help but read these posts as asking for *permission*...

"Am i allowed to tour on a unicycle?"
"Sure, Billy, so long as you're home by supper."

Nothing against the OP, of course; it's just a quirky way my mind reacts to the frequent "Can i tour on a _________?" posts.

Personally, I wouldn't want that windsor cross bike for tours. Why? As others mentioned, the carbon fork. As you mentioned, the double crank. As someone might have mentioned, the aluminum frame. As i'm about to mention, the 20speed rear, which you can't make a bigblock out of. Anything else? Sure, but i'm not going to go into it, because i don't want to enrage anyone.

The truth is, many have toured on aluminum bikes, with carbon forks, with double cranks, brifters, 10speed rear, etc. You can do it! But, if you're looking for a tour bike, why not get a tour bike? Any real tour bike will accept cyclocross knobbies, and any stumps/logs/bumps that will require a higher bb shell will surely wreak havoc on your panniers anyway, so you won't need 'cross geometry.

If you love/want a tour bike, and you intend to tour a lot, and you don't have a bike, get a tourbike. If you already had the cross bike, i'd say "ride what ya got".

If you really want a cross bike, and you just plan to use it for tour stuff occasionally, get a cross bike. But, maybe not that cross bike. Maybe more like a volpe or a crosscheck.

If you want to compete in cross competitively, you'll want something quite different than all the bikes mentioned on this thread.
