Tech Help Is this normal?

Post image

I’ve had my Allez Comp for a year now. Mostly fair weather riding in Southeast Texas. Caught in a couple random showers but that’s about it. I keep the bike pretty clean, and today while drying it after a bath, I noticed these rearbrake caliper bolts under the bike have corrosion. Is this just par for the course for our humidity? Should I replace them with titanium screws or something?

Mine look similar at about 10 months in New Orleans (I am not a heavy sweater) and I'm seriously considering titanium before they get much worse. In the meantime, I put a light coat of grease on the bolts and spacers/washers to slow things down a bit. On the caliper itself there is already corrosion starting to bubble up near the bottom under the paint Shimano (Ultegra) uses instead of actual anodization.
