I have a lot more knowledge about rusting permanent hardware on sea cliff climbing than bicycle corrosion.
The long and the short of it is that titanium simply doesn’t exhibit the corrosion you see with aluminum or even higher quality stainless steel. No stress crack corrosion and no galvanic corrosion. Also why you see titanium as the main metal used in orthopedic implants.
Its more than salt and air. The minerals dissolved in wet limestone, plus sun, salt, and heat are quite effective together.
So what can be done about a “Florida bike”
Ideally I think a 1 piece carbon bar and stem combo. Otherwise, a carbon bar with titanium stem (use plenty of ti prep) should help. I would worry that brake clomps would become a sacrificial anode in that setup.
What about prevention? Headband, wristbands, and a huge fan indoors.
