I bought a kids bike in April last year and my LBS only had two 16" bikes left at that time. I had been thinking of getting a new CX race bike and was worried about availability, so a few months later I started searching and was able to find options from a few different shops. I remember at that time my LBS telling me they were completely sold out of any sub $2000 bikes for 2020, but that higher end stuff was still available.
Fast forward to a few weeks ago, I saw a note from them on social media that they had two fully loaded Cannondale SystemSix's in stock, but otherwise every Cannondale road bike was sold out for 2021.
