Cyclocross bike for long distance day rides?
I currently have a 21 speed GT Aggressor mountain bike that I've setup for the street with slicks and spd pedals. It is a really great bike, but I am looking for something that is more comfortable and better geared for longer rides. Right now I am riding 30-40 miles every day with a little gravel and a few hills, but nothing heavy. I don't need to carry panniers or anything, I just want a bike that can handle these conditions while boosting my average speed, and possibly take me 100 miles if I feel up to it. I have an opportunity to buy a 2006 Jamis Nova for $300, but the price sounds too low for what it is. Would this be a good choice for me? Or..?
