GPS used to be fancy, and is now affordable
Carbon frames used to be fancy, and are now affordable
Carbon aero wheels used to be fancy, and are now affordable
Hydraulic brakes used to be fancy, and are now affordable
Wireless shifting used to be fancy, and is now affordable
Good tires used to not even exist, and are now available albeit a little expensive
Lighting used to be heavy and annoying, now it clips to anything and you can light up the road with something the size of your thumb
Wide range cassettes used to be unimaginable, now some lazy people are even going 1x because they got filtered by 2x

It seems like it's all been done. Seriously, what's left. What else is there to improve? We even got bonuses like thru-axle, 3d printed saddles, internal routed everything, and aero frames/cockpits, which let's be honest, you weren't really expecting were you?

Can the cycling industry outdo itself or is it now a plateau of stagnation?
