In the midst of the pandemic, I managed to grab a full ultegra bike for $400. Real beauty of a hand made Italian stallion. The only reason why I got this bike was because the owner had just bought a brand new gravel bike, because that is all the rage right now in the bike world and people are trying to get rid of their road bikes. Gear acquisition syndrome has plagued this sport since its inception, but it works in the used cyclist's favor when you can reliably get gently used gear for dirt cheap.
Word of advice from one cyclist to another: resist the trends. Buy used. Buy old. Spend used car levels of cash on anything else in your life besides a bike, because in 10 years that $1500 bike will remain the same great bike it was but will become $200.
