Following up on this...
Decided to make a project out of it. I ended up not sandblasting it, which I think was the smart choice. I've come to appreciate the loud branding. I also saw a couple of these red Cannondale frames fitted with some darker components which I liked so I decided to commit to all black.
I'm pretty thrifty online so the only things I paid retail for were the tape, bb, chain and cables/housing. Everything else was purchased [very lightly] used or new through a reseller. The components are pretty much all Shimano:
Crankset: Shimano 5800 compact with 165mm crank arms (craigslist)
BB: Shimano BBR60 (ebay)
Shifters: 5800 2x11 (facebook marketplace)
Brakes: 5800 (ebay)
Cassette: 5800 11-28t (fb marketplace)
RD: 5800 short cage (fb marketplace)
FD: R7000 (fb marketplace)
Saddle:
Fizik Antares R1 Versus Evo (offerup)
Pedals: Shimano PD-A530 (a bike shop in cali called bicycle czar)
Stem: Fizik Cyrano R5 (fb marketplace)
Bars: Some random compacts off a newer Felt bike (fb marketplace)
Chain: KMC 11-speed (amazon)
Wheels: Mavic Aksium (offerup)
Tires: Gatorskin 28mm (came with the wheels)
Tape: Zipp Service Course (planet cyclery)
