I had a Trek 1000 that got stolen a couple months ago and I'd like to replace it. I'm thinking of going with some kind of mountain bike this time, or at least something a bit more agreeable to mud and rain (I'm in the Pacific Northwest). I also don't need a drivetrain with 20+ gears. On the Trek 1000 I kept the front sprocket in the middle and that was all the gears I needed for commuting. Anyone have any advice for me on which ones I should check out?
