Did I need to state "little chance of seizing when greased"? When the previous sentence said to apply grease? Most assemblies of steel bike parts that have been abused and neglected will transmogrify into a single rusty lump before crumbling to dust, all the quicker when used in a maritime environment or an area that salts roads. There are some arid environments that corrosion proceeds at a much reduced rate, but generally the low population density of those areas means there's not much stuff there apart from antique mining equipment.
