My fiance would like to get into road riding and cyclocross racing. She has never done either. I have been road riding this whole past season but due to low funds we couldn't get her a road bike this past year. We went to our first cross race this past weekend and she fell in love with it. What are your thoughts about buying a cross bike and putting road tires on it for general riding? Will she be able to stay with the road riders or are we better off buying her two bikes for two different purposes?
