Electrolysis on wheels?

I ordered some new wheels from Spin Lite in Georgia. We went through the various options and I ordered brass nipples on aluminum rims. Later on, I remembered that brass eats aluminum by means of electrolysis. It's a real problem for the sailboat crowd, and I ride to the edge of San Francisco bay, so there is some exposure to salt air. Has anyone had experience with this on bike wheels? Did I make a mistake? Your thoughts please. bk

I believe all of the brass nipples will be plated with another material (nickel?) for corrosion resistance and to prevent the problem you are concerned with.

Brass is OK with aluminum, and brass nipples work fine. I have wheels that are over 20 years old that are still servicable.
There's not much brass on modern sailboats. The worst corrosion problem occus between stainless steel and aluminum.
