i am getting back in to biking. i have an older cannondale mtn. bike, bought it in the mid 90's and am looking to do a little bit of everything. i want to ride roads and have the ability to do some off road stuff as well. i am thinking that what i currently have will not be all that suitable for road riding and wanted to get some suggestions on some bikes that i might want to take a look at. i have a pretty busy schedule and am not sure how often i am going to be able to ride, so i don't want to sink a lot of money in a bike...my ideal cost would be no more than $525 and i wanted to see if anyone has any good suggestions for a bike in that range.
