If left long enough, two different metal elements will corrode each other without the need for water. It's got something to do with the different electrostatic properties of metals at an atomic level but that probably won't be noticable unless you leave you bike so long that the next time you use it it's for a trip to collect your pension! And for you ruthie, that many many years away! |
