My wife and I are new to cycling and we went looking for new bikes today. We went shopping at the LBS and were shown both road bikes and cross bikes. We started by looking at road bikes but after we told the salesman where we would be riding, he suggested the cyclocross style bikes and I'm not sure we really need them. The area we will be riding is a compact dirt fire road, around a local lake. It is mostly flat and smooth with no obstructions. I asked if we could put a more agressive tire on a road bike and acheive the same effect as a cyclocross bike. He said that he would not recommend using a carbon fibre fork in an off road application yet when I got home, I looked on the web and I see that meny manufacterers of cross bikes use carbon forks. What do you guys (and gals) think of that? Also, what are the major differences between cross bikes and true road bikes? I really liked the Cyclocross style bikes but the Trek 1000 I was looking at is much cheeper and when you are buying 2 bikes that is a big factor. Thanks in advance.
PS I was looking at Trek 1000's, Trek X01, and the Lemond Poprad any info good or bad on these bikes.
