My wife and I saw this bike today at my LBS for about $565, down from $765. Although I've been biking for years (and commuting for months), I've never really paid attention to components and such. Thus, I'd like to know from more experienced folks what you think of this bicycle as a commuter, and for that price:

It's the Bianchi "Castro Valley".

My commute is 5 miles each way, no serious hills. Currently I ride a 2001 Specialized HR Comp MTB with slicks and never come out of the largest front chain ring, so for now having only one front chain ring on the Castro valley wouldn't be a major issue. However, I hope to do longer rides on this bike, so I'm wondering if this bike could be fitted with a double chain ring?

Thanks in advance for any and all input....
