So I’ve built a shelter to keep the rain off my bike and intend to keep it outside most of the year. It’s just a sloping corrugated plastic roof to keep the rain off it.
Will this be enough do you think?
I have stored a bike for around a year below a shelter outdoors. The bike was in such a location that no rain ever directly touched it but it sure was unprotected from humidity.
- Brake lever rubber hoods were so sticky after the storage that I had to change them. A simple roof doesn't shield from sunlight, and sunlight deterioration of rubber is rapid.
- Brake pad screws were rusted -- not so much that it would affect their function, but it sure looks ugly.
- Rear hub made of polished aluminum was severely pitted. Not so much that it would affect its function, but it sure looks ugly.
The frame of the bike in question is butted chromium molybdenum steel. Its outside surface didn't rust. I haven't looked inside the tubes, though. It's possible there's internal rust -- not so much that it would affect its function, but a perfectionist might consider even minor internal rust as a problem.
If you don't consider minor surface rust visible to the eye to be a problem, and if you are prepared to change all rubber parts you touch with your hands (i.e. brake lever hoods), then go ahead. But I think you will be far more satisfied in a better shelter, something that isn't humid and something that perfectly protects from sunlight.
