Wide saddle: Generally one category up from what would normally be on there - touring replaces racing, cruiser replaces touring, mega women's saddle replaces cruiser.
Wide handlebar: Most stock road bars are uncomfortable for me because they're too narrow, although I'm generally comfortable with most upright bars. Like the saddle this is due to my unusually large build.
Strong pedals: Cheap nylon bends under my feet and the bearings go quickly. Block pedals work well for my classic bikes.
