I am looking to buy a new road bike, and don't want to go with a used one because of the problems that can happen. I am looking to spend no more than $1400. I am used to mountain biking, but moved to a flatter part of the state where there aren't many trails, so now i would like to get a road bike. what's the difference between a double, triple, etc. i am very new to the whole road bike thing. anyone have suggestions on what brand/model to get? also, what's the difference between a normal road bike and a time trial bike? before with mountain biking i always road specialized, but someone told me cannondale is the best for road???
