You've got your priorities straight. An admirable school project, focusing on a single problem (corrosion). Bike drivetrains have a lot more going on that can also cause wear, i.e., lubrication, cleanliness, riding environment, etc. A highly corrosion resistant chain may not outlast a less resistant one if for instance lubrication & cleanliness control life. I've never even thought about corrosion but I don't live where they salt the roads. Heck, it doesn't even rain enough around here. "Peroxide, salt & vinegar". That sounds pretty nasty without thinking about the chemical reactions. That's must have been a fun project for her. dougP On Friday, March 27, 2015 at 4:28:00 PM UTC-7, Bill Lindsay wrote: > > My daughter did her 5th grade science project on rust proofed bike chains. > We bought her a bunch of new chains (including a Wipperman) and cut them > into lengths for her to do all kinds of mean things to them.
