My 2005(?) Trek 1000 road bike spent last winter on the balcony ( I live in Southern California, so winters are very mild here. ) Inspecting the bike for the first ride after the winter, I've discovered that some parts of brake calipers got completely covered with rust.
I'm thinking to replace the calipers with brand-name components like Shimano.
A few questions.
1) Why can't they make the whole caliper out of aluminum & stainless steel? I'd expect such low-quality materials in a $100 Wal-Mart bike, but not in $500 Trek?
2) Is this going to happen again with Shimano? Should I get more expensive brake calipers such as 105, or is Tiagra/Sora going to be enough? I'm not a competitive rider and 100-200 g weight difference is not significant for me.
3) Is it unsafe to ride like this?
