I am an engineer (not a Dentist) and I paid for my recent 1X13, disc brake, carbon fiber frame, sloping top tube, aero design, carbon wheeled, 28mm wide tubeless tire, carbon bottle caged Time Scylon with a card that says "Platinum Plus", and it is more enjoyable to ride for hours at a time than my steel or titanium bikes. Please note well that I am past my "full retirement age" and still working because it is enjoyable to be involved in designing modern products and learning new things.
Oh yeah, the crank arms, handlebars and seat post are also carbon fiber, and to make it even worse, the seat post is a proprietary design so I can't go buy a steel one on eBay. Now, can all those of you who think modern bikes are inferior please piss off.
