+ 1; that was really good info.

We had a lot of problems with campy NR headsets in the shop I worked in on the 80s. The roads were rough (New Orleans has some of the worst roads in the US) and headsets got chewed up. Roller bearing headsets like the stronglight A9 took care of that problem.

It looks like they're still available ??, http://www.amazon.com/Stronglight-Cl.../dp/B002WMRJQ2

Here is a good thread on roller bearing headsets:

I may have to pick one up for a project I am working on.
