Tried rebuilding a vintage Campagnolo hub with loose bearings instead of a cartridge

I grabbed an old 1970s Record hub from a bin last month and decided to go with the original loose ball setup instead of swapping in a modern cartridge bearing. After packing the grease and setting the cones by hand, I got a smooth spin with zero play that actually felt nicer than any sealed bearing I've used on newer wheels. Has anyone else noticed loose bearings can still hold their own on a daily rider if you take the time to get the adjustment right?

The key is getting that cone tension dialed in. I've found a little trick with using a sharpie mark on the cone nut and counting quarter turns as you snug it down, makes it way easier to find the sweet spot again if you have to back it out. The old Campy stuff has such nice hardened races that a proper loose bearing setup just glides, those tiny little balls roll so much smoother than the big chunky ones in a cartridge. Plus you can pack way more grease in there without worrying about seal drag, which i think helps with longevity on a bike you actually ride in the rain.

One thing people miss with old Campy hubs is the grease choice matters way more than they think. I run mine with a super light oil-based grease, almost like a thick oil, instead of the heavy waterproof stuff. That way the bearing drag is even lower and the hub really spins forever. But if you ride in the rain like @wesleybutler mentioned, that thin grease washes out fast and you end up with rust pits in those beautiful races. I had to relace a rear wheel three years ago because I got lazy and didn't repack it after a wet century. So for wet weather, you almost want a thicker marine grease that stays put, even if it costs you a tiny bit of spin. The tradeoff is real between smoothness and protection.
