It is evolving. I don't want to start another moment in the forum with my 'pastie' crown race.
Coming from 72.5 to 70.5 degrees in Head Tube Angle (relative to the ground) appears to make quite a difference in trail. Now I just need to find the fork that is long enough to do the same as my proof in concept setup. I could have bent the rake offset back, but my weight and metal fatigue isn't the best match.
I got one more project after I've settled on the fork, but it is more attuned to bikes that already have cranks forward.

In case you missed it.

Also a meniscus doesn't take into account paint flakes, grease and all kinds of nature happening.
By the way, they are back in business.

Now all those rusting hulks can thank the government for the delay of this technology.
Thankfully Aspirin is grandfathered in or the government would be going after that.

No electrolyte, no free transfer of electrons between the steel and the sacrificial anode, and no significant protection. Your plan is goofy but I reckon it won't affect your ride.
Good luck.
Good luck.

America's leading HVAC specialists are using sacrificial donor metals on their heat pumps and air conditioners up and down the south east coast to South Carolina's coast.

If you're letting your bike get wet and stay wet (like an air conditioner or a boat hull) then you have bigger problems* than cathodic protection can solve.

The condenser coils are dry with the exception of rain and condensation while not operating. Any outside condensation on the condenser coils is quickly dried up when the air conditioner starts to operate.

Does a sacrificial donor metal work in humid salty air?
Some people seem to think so.
Jesse thinks it is pretty straightforward

I think a dab of zinc paint on the exposed steel hole would have been more than sufficient.
When the bike is moving and bumping along I suspect that the water bubble of a smaller hole would easily have been broken and released, and I fear the larger hole may be more of an invitation for water to splash in to the hole and gunk up your bottom bracket bearings. I do not think the larger hole is enough to compromise any strength however.

The sacrificial donor metal I have weighs 2.4 ounces.
It isn't covering up the bottom bracket drain hole, it is behind my kickstand.
All that matters is if there is a voltage potential.
Boats move.
Air conditioners in humid salty air are stationary.
Yet both benefit from a sacrificial donor metal.
"... I fear the larger hole may be more of an invitation for water to splash in to the hole and gunk up your bottom bracket bearings."
Possibly so.
Has anyone offered what the dimension of the hole at the bottom bracket should be?
And can they tell us how they reached their conclusion?

I'm glad that you know more about cathodic protection than everybody that actually designs those systems. I'm sure you'll be very happy.

It is a sacrificial piece of metal.

It will corrode setting up a voltage that will protect steel and aluminum from corrosion.
Normally used on boats but this one is specifically used in freshwater.
So any mild corrosion of this magnesium will set up a voltage potential between the two metals.

Psst. Stainless steel for high humidity salt air environments.

All of my sailboats have had zinc sacrificial anodes and hull mounted ground plates for radio and standing rigging grounding.
