This bike reminds me of my Specialized Sirrus Sport Disc. I hadn't researched it properly and ended up buying a bike that is a bit ill-suited to what I plan to do. But then again, it's biking on my Sirrus that got me into touring again, so it was a chicken/egg problem in my case.
Nevertheless, if you already know that you want to tour with your new bike, you might as well buy one that was built for that.
Problems that you will probably encounter if you buy that bike:
Disc brakes. You'll have a hard time finding proper racks that fit well, and even then, you'll have a bit of hacking to to.
I managed to find an Old Man mountain front rack which fits properly (the AC Lowrider, which attaches to the fender braze-on (i don't have the "upper" braze-on in front) and fits with the braks. Even then, you'll probably have issues with the "width" of the brake, which might end up rubbing against your panniers.
In the back, you'll have the same problem with the brake which will restrict your choices of rack. I got the Axiom Journey Disc.
The short chainstays will cause different problems:
- Restrictions to tire sizes (I have 700x28c and _maybe_ I could fit some 32c on it). This might be important if you tour on converted railroad tracks which are often covered with crushed limestone. Up here, we have thousands of km of them, so touring on them is definitely a possibility.
- Fenders: most won't fit. Especially if you go for fatter tires.
- "Twitchiness". A short chainstay (smaller wheelbase) make a more nervous bike. This is really cool for commuting and zipping around town, but on a loaded bike, it can become dangerous if you don't have sharp reflexes.
- Heel clearance. In order to accommodate your feet, you'll have to push your panniers back, which will push back the center of gravity of your rear panniers behind the center of the rear wheels. This doesn't help the bike's twitchiness as the front will be light and the back heavy. You might need to have front panniers, not to bring more things, but to put some weight in the front to compensate that.
That bike might also have a steeper headset tube angle, which would make it a bit more nervous than a touring bike. I'm not 100% sure about that, but I suspect it to be true. You should probably ask around for this one.
This said, I'm leaving thursday morning for a 4 day tour (fully loaded). So, even if you don't have the perfect equipment, you can tour. What you need to do is determine the use you will make of the bike and buy one that's better suited for that use. If you plan on commuting every day and perhaps going on a few weekend tours and maybe a weeklong tour per year, that bike might be a suitable candidate since your main use will be a daily commute. If you don't live in an urban area or will use it mainly for touring, then you might as well go for a real touring bike. I know I wish I had done that...
