Need some help. I am looking at buying a bike off a friend. It's a GT Edge Aero, but i don't know what year it is and can't seem to find it on the web. The bike is a bright yellow, almost florescent and frame and forks are carbon fibre. The GT logo on the tube is in red. If anyone could shed some light in the situation I would be very grateful. p.s. all the components have been changed, but possibly it used to have 105 through out.
