My commuter, errands, bad weather, all around use bike. Schwinn SS DBX, 2006, it is a well thought out and executed build for a multi-use bike. Mech disc brakes, can be switched to cantilever, rack and fender mounts, aluminum frame/CF fork, room for at least 38mm tires. It has a good geometry for commuting and still can be set up pretty aggressive,has a very cushy ride with the wider tires and the same rims will take 23/25mm no problem. On the heavy side as it is set up now, but can get it down to around 21 lbs. with different set up. Schwinn mostly gets a bad rap these days, probably deserved, but this model has a great reputation and was given rave reviews in Bicycling Mag, for what that is worth. It has served me well and I change things on it as the need, or wants, arise.
