I just wanted to plug Trek in general. I bought the 1500 WSD in April and I absolutely love it.
. Two of my girlfriends have specialized bikes (Dolce and Elite) and I was sure I would just love the Elite, but I didn't. The Trek just felt so much better for me. Everyone is different in how they fit on the bikes and what feels best to them. But my plug for Trek stems from the fact that for the money, it came with much better components than any of the other bikes I looked at. Since they own Bontrager and get those parts for cheap, they can spend more on the Shimano parts so you get the higher end components. Even as a beginner, I could tell a difference between the "entry level" and the higher up components just on my test rides.
The best part about going up hills is riding back down!
