Any discussion of Trek's 520 around potential buyers should feature a warning of limited tire size due to their choice in fork. At least until Trek thinks about it long enough to realize that a bike they're pushing for use in remote places should be able to *easily* mount true 35mm tires and the rider's choice in fenders. The cheesy rack is a laugh too but can be removed and replaced by just about anyone who buys the bike.

From visiting their website you don't get the feeling they really care about touring. They do happen to have supported tours but these feature a profit for them and your opportunity to ride the tour on either their latest carbon fiber race bike or a 7.5 FX Hybrid. Wow, they don't even use their own touring bike for a National Park tour.

Cannondale seems to really enjoy the prospect of touring. You'll have a hard time of even getting the "Touring" link off the top of the screen while visiting their site. On the page featuring their latest race bike; the Touring link is still up there. Cannondale
And as they say... "TOURING - A testament to Cannondale craftsmanship. Our first bike was a touring model, revolutionary for its time. Its lightweight, aluminum design—combined with painstaking attention to detail—met the demands of touring enthusiasts globally. Today, little has changed: Fender-ready with generous clearance, three sets of bottle mounts, rear rack, and puncture protected tires with reflective sidewalls. Cannondale Touring—for panoramic views since 1983."
