I was recently at a Trek test-drive event and let me tell you, people love Trek bikes. Unfortunately, there were no Treks that fit the Bikes For The Rest Of Us bill to ride that day. I did spot a very fine-looking Soho in person. All the bits that make the Soho a great commuter are there... internal hub gears, roller brakes, fenders, etc. It has a belt drive instead of a chain as well. Keep in mind that the stem on this bike is of the threadless (non-quill) variety; you can't raise the stem once it's cut, so make sure the bike fits.
The components of the Soho are top notch, but unfortunately the price up there... over $1100. I wish more of these great features trickled down to other bikes in the Trek lineup. I'm not expecting a Gates Drive on every bike, mind you; yet some fenders, roller brakes and chain guards would be nice on some of the mid-priced bikes.
