I currently ride a Schwinn comfort bike. Its a fun bike but I feel like I sit too upright and I'm always straggling behind my husband on his Fuji Absolute. I'm looking for something faster with a little better position (but not too aggressive - I'm much too uncoordinated for dropbars) and I'm thinking a flat bar is probably the way to go. What do you think of the Diamondback Insight or the Fuji Absolute 2.1? Performance Bikes has the 2013's of these for just under $400. We ride paved paths of about 15 miles a couple of times per week, but would like to increase both distance and frequency.

Also, I'm looking at this Specialized Vita on CraigsList.

I think its a 2011 and they're asking $350. If this is the better bike, what do you think I should offer?

Thanks in advance for any help you can offer.
