I have not built a bike around a crank. When the De Rosa Pro was delivered, I contemplated what Campagnolo I was going to hang on it. I was thinking of C-Record but the prices were hard to swallow.
I had either a Chorus o Record crank so that was the direction. I ran across a wheel set with 10 speed Record hubs, cassette and Ambrosia Nemesis rims. The direction was now clear.
Secondarily, the wheel set had black spokes and red ones on either side of the valve stem so black and red was the set.
@IAB - Lust on that Frejus!

Not a roadie but this crank is inspiration for this frame. Adding lots of STX stuff to it too.

I know a guy who's building a bike around a Campy Portacatena (chain rest at the right-rear dropout). He has a lot of bikes though, and he's tried every other combination under the sun... almost.

Go easy on that granny ring, I'm pretty sure they are a weird BCD that will be practically impossible to replace. At least they don't come up on ebay very often.
Great cranks though, pretty and strong. We used to put them on custom Davidson tandems in the early '80s. The lore I heard (probably from whoever the dristributor was), said these were made from the same forgings that Campy cranks were made from, so only the post-forging machining was different. Take that story with a grain of salt, but they are veyr similar. But the GPM version has thicker spider arms.
EDIT: well maybe those rings aren't as rare as I thought, here's one for sale at "Bike Recyclery"

Couple wacky cranksets that are awaiting the "just right" bike for them
Steel cotterless Gnutti with splined spindle interface. Luckily was able to score a remover, which is a different thread than anything else. Dunno how I ended up with three spindles.
And the Williams AB-77, that I did have one a bike for awhile, but I sold that bike and kept the crankset.
Again with the three spindles! I think in this case it's because someone gave me their spare parts after their left crank's splines got stripped, from riding it loose. I've heard from British guys who were racing back then, it got a reputation for stripping out the splines, but mine were reliable for me. I raced and trained on 'em and I'm big. Possibly user error.

Any excuse is a good one!
But I think a better example of building a bike around a component is the brakes. Brakes determine the size of tires that you can fit, which in turn gives a strong indication of what handling you're probably going for. And you can't really change from a short-reach brake into a long-reach brake on the same bike (short of switching to 650b wheels or the like). Can't change from canti's to centerpulls on the same frame without serious surgery.

The new set cleaned up nicely and probably has more miles left in it than I have

Must take different granny bolts, if nothing else they have to be a little shorter to not bottom out in the "blind" holes.
Do we know the dates on those? I'm guessing the one with the through-holes is older, blind holes newer.

The one on the Gazelle is different though. Interesting how the granny attchment points aren't tapped all the way through the spider, not visible from the front side. Elegant looking too.

I just had an interesting thought which is rather the inverse conundrum of this thread: in my collection and planning of my next vintage build, I have nearly all the components set aside EXCEPT the crankset. I just keep going back and forth on what to use. I suppose that is more of a common "problem" than building around a single component.
