Ride it for a while and see how you like it. By that time you will have some idea of the items that don't meet your expectations or comfort. You will also have a better idea of what you really want/need and can decide if it is worth a couple of simple updates or a new bike that has all your news want and wishes. It is usually financially better to buy a new bike with what you want on it and sell the old one than just upgrading a bunch of components on the old one. Regardless of what you do as the addiction progresses chances are you will want a new bike anyway ( N+1 )
