My Trail Way hybrid (also from Target) is similar. Shifters and RD from Shimano... Mind you, I've replaced half the components on the bike in the first year and a half of ownership (3K+ miles ridden) - some by choice, most out of necessity. The wheels are the big issue. 24 spoke aero wheels on a 30 lb. bike are a ridiculous proposition, especially ones as crappy as they put on. Live and learn, though, I guess... Never buying a box store bike for myself again.

That being said, the frame is pretty light (if a skoash small for me), and my upgrades/replacements have made it into a decent bike.
