I have decided to get back into shape and started riding again. I need a new bike. I currently have an old Trek mountain bike that served me well in the hills of Pa, but is not very good on concrete. I am trying to decide between road and cyclocross. I ride about 20 mi every other night, looking to do more, but not sure what is best for me. I have looked at some Motobecane and Mercier bikes that have 18 to 27 speeds, is that really that important? Also, I am not familiar with the brands, are they decent bikes? I am looking spend under $1,000 and looking for the right fit. Any advise would be appreciated.
