Pretty much ride the Zwift Concept (Tron) bike for anything flat and rolling. Please to don't tell me how 'unrealistic' this bike is, don't care. I worked hard for it.
I got an in-game Specialized Allez Pro for climbing.
And a virtual Cervelo P5 for racing with whatever ENVE wheel set is best for the course.
Sometimes I take the Zwift Areo bike out because I got a special color scheme for it from some event, so it looks really cool.
I have over 4million drops, don't really know what other pretend game bikes or wheels to buy.
