Starting with a generic sort of frame and fork, the Trek parts aren't going to give you a faster, smoother ride. Except for the wheels and tires. The most logical approach would be buy an inexpensive bike for the commuter and just move the wheels over, keeping the Trek intact for when you want to ride "expensive road bike".
