umm dont get me wrong here but by grounding anything to the frame
will create a path for electricity to flow anywhere along the frame including the head steam and tripples if it so decides
The front end and bearings are electrically connected, this is true. They will always be at the same voltage potential as the rest of the bike's frame. But that's OK. Volts aren't a problem. Even if you charged the bike's frame up to 20,000 volts, that wouldn't hurt the bearings because the amount of current needed to get the front end at the same potential would be minimal.
What matters is amps, or current flow. If something is grounded to the front end, then the current has no choice but to return through the bearings, and that's when you can get into problems.
Electricity takes the path of least resistance, so if there's a ground to the frame, the current will flow through the frame to the battery's ground connection. It's not going to take a side trip through the steering head bearings and front end unless you force it to.
Anyway, this isn't an absolute, where you ground to the front end and your bearings are toast within an hour. It's a slow process. In fact, it's probably slower than the natural degradation of the cheap steering head bearings that our bikes come with. But it is an effect, and is easily avoided by picking a better ground location.
