Campy Zonda wheels- lateral play problem

[Forza20]

My Zonda wheels, new in 2008, 1st gen/ non tubeless,were great for the first few years but then developed a lateral play problem that could not be adjusted out.

I would tighten the adjusters but then they never spun freely and the play would return in short order.

Speaking to various Campy offices, including Italy, and also Campy tech specialists, didn't provide a solution.

Until recently...

It turns out that the hub cups, steel bearing cups, pressed into the aluminum shells, had come loose. Both cups in the front, and the ND cup in the rear, were very loose and spun easily .

The cause.. likely some water penetration over time, wet weather/ puddles in the fall and spring, that corroded the exterior steel surface of the cups, and, to a lesser degree, the adjacent aluminum surface of the shell.

And this is despite annual cleaning, regreasing,etc...

The solution...

2 part epoxy used to fasten the cups..

The result....now as smooth running as they day they were born.

Amazing !
