hopefully carbon fiber continues to get cheaper, because having a lighter bike really does make a difference on climbs. that said, anybody can go up a hill in a low enough gear(!), but psychologically it can still feel like a lot of work to pedal so much and go up so slowly. so part of it is learning how to ride. for that reason i agree hills are a (surmountable) barrier to entry and probably hillier places have less…
Carbon frames have significant drawbacks compared to metal frames, especially for everyday bikes. Sure, the weight reduction matters when you're racing, but carbon frames don't stand up very well to the bumps and scrapes of a bike commute. If you crash a metal frame, it may bend a bit, and if it's unsafe to ride, it's generally immediately obvious. A carbon frame can look perfectly fine, but suddenly snap at an inopp…
carbon fiber is extremely strong for its weight -- if you have an accident that is going to render it unsafe, you are sure likely to know. its true you can bend a steel frame back into shape (not so much with aluminum), but steel also rusts, and with anything the quality of the build matters (what do the welds look like, is it lugged, etc)
in any case im talking about a future where carbon is cheaper and replacing it doesn't cost the equivalent of a college degree
