Tell me what you think! I was thinking to buy a road bike because of the things cooker has pointed out (smoooth ride, lighter weight, etc.), but then i started thinking in the skinny tires and how often will my rims be damaged... Altough i will like a little more info on that "road bike with fatter tires"!

Thanks a lot!
