I remember seeing an old picture of the USA 1968 (Mexico) Olympic Road Team
posing next to their bikes. Some of these bikes were equipped with the
Bivalent Hubs.
I think its the
threads on the aluminum body that have a tendency to strip. There are very
few threads that the steel "male" spline engage into on the aluminum hub. The
thing to do is to remove the spline ( there is actually a Cinelli tool for
this, pliers will do the job with less glamour. ) and dap the threads with
Green Loctite. Stripping a Cinelli Hub will ruin your day.
