I went to the biike shop today. Basically told the guy I was interested in street and maybe some light trails. Tried to shift me toward a Navigator but from what I have read on this helpful forum, Navigators aren't the best option and MBs can do it all with the right tire. At any rate I asked him about the Specialized and he said that it is much more geared toward trails then the 4300? Seems wierd. Any suggestions?
