I went for a mid tier model (Cannondale Quick 3) and upgraded everything. I don't know if I saved anything compared to the Quick 1 but at least installing things will give me something to do during lock down. The frames seem to the same for the most part.

So far, this is what I've purchased:

Shimano 105 components (50/34 175mm crank, 11-32 cassette, chain, clamp on front derailleur and long cage rear derailleur, BB80 bottom bracket and SL-RS700 shifters).
Ritchey Zeta Comp Wheepset with 11 spd freehub.

I had to get a few extra tools as well but at least I'll be able to work on my bike from now on.

The Quick 1 costs $600 more and doesn't have a Shimano 105 crank or bottom bracket, so I still feel good about going this route. Unfortunately, my bike's shipment has been delayed but at least I have most of my new parts.
