what bearings in a vintage Campagnolo Record track headset?

This is a question that would as well fit in the Vintage forum, but what bearings are used in a vintage ('74) Campagnolo Record Track headset? Standard campy bearings like in the road Super Record or Nuovo Record, or something more exotic and erotic? Thanks!

Most Campy headset use 3/16" bearing balls, while most other cup-and-cone headsets use 5/32" bearing balls. When in doubt, MEASURE!!!

If you've got the headset, then when you overhaul it and want to get new bearings, just take some of the old bearings to your bike shop (or compare to bearings that you have if you've got extra bearings sitting around).

Thanks. I bought the headset without bearings and don't have an array of bearings in different sizes handy. I thought campy used 5/32" bearings for their headsets with some exceptions.

Hmm... most Campy headsets use 3/16" balls,but there may be some exceptions. Maybe someone in the Classics & Vintage forum has a similar headset and can check the ball size for you?

I actually have this headset on my paramount track bike, I can't remember the size of the bearings, but I had the shop install it. I'm pretty sure we tossed the old bearing that had the retainer and went with loose bearings. I don't like to install those old threaded headsets myself...I just don't have the touch. just bring a few of the bearings into the shop and they should be able to get you what you need. but that assumes a real bike shop...these are becoming rare today. many of the new shops are these slick retail stores in a strip mall with lots of space devoted to selling you a new bike with clothes, a new pump, a trainer and a bike rack. You need a shop where a third of the place is their workshop with little bins of small parts.

You can take a headset without bearings to your LBS and stuck some bearings in there and see how they fit. You could also compare the curve of the bearings to the curve of the headset cup.

That said, I understand that it would be nice to know the definative answer to this question.

I would have liked to go to the shop with the bearings but will go there with what I have and am pretty hopeful they will have adequate bearings sitting around. I'll report back.

what he said
the pista headsets used the smaller balls to lower the stack height even more
