I'm the same keep changing. That frame was like new when I bought it 3 years ago a barn find. you still got the Dutch bike sticker on the down tube. And the mavic sticker
You're not alone. I built a Coppi with an 11 speed Ultegra, rode it maybe 4 times and now changed the groupset to a new neo retro build. Sorry for crossposting.
That's my bike!!
