Talked to my LBS, who handles Cannondale, and they said they couldn't guarantee that they could get me anything, so if I could find something to go ahead and grab it. Took about three weeks of searching to find a SuperSix Evo in my size, bought it from a shop in Jersey and had it shipped down. The day I bought it, Cannondale raised the prices on all SuperSix models by $300, so it was good timing. Just the state of the market. There is still a big ripple effect in the supply chain, epspecially for components. I've heard that a lot of manufacturers have frames available, but no components to build them out.
Now that I have a solid road bike, and my gravel bike, I'm pretty much set. Stocking up on some consumable spares as I find them available, just to be safe.
