my dad has charged me with finding him the right bike. unfortunately the only thing i know about bikes is that they have to wheels and gears. he absolutely wants a specialized bike and he will be using it for riding to work and back so its only street riding. it HAS to be specialized (the brand). he is 6"2-6"3 and about 220-230 pounds. he can ride a bike but he is not very athletic.
edit: cool! there's a advertisement in my post!!
