The way I look at it there are two markets being discussed here. First being the current bicycle market including used late model performance bicycles. This market ebbs and flows with the sports popularity.
C&V is separate from the above as it’s typically fueled by demographic drivers. The current desire for mid 70”s to late 80’s bikes is from people who finally have the funds and time to pick up items lusted after years ago yet unaffordable by the part time jobs or paper routes at the time. These people are aging out of the sport and have acquired their fill. These collections number from the dozens to hundreds of bikes and all will be released into a soft market for decades to come. Like previously mentioned it’s a great time for those who wish to continue to acquire and collect not so much if the intent to view this as a investment of any sort.
