Wow great info guys thanks so much. I don't know much about bikes so the diffrences between the 7.1, 7.2, and 7.3 don't make sense to me. I understand better tires and better frame but the rest has me confused. I'm sorry I'm a complete noob and as of right now I'm liking the 7.1 for the matte black finish. (please don't throw a brick at me). I'm just going to use the bike to ride around the block and ride it at the park. Would it still make sense to spend the extra money on a 7.3 ? Once again I'm sorry for asking these noob questions.
