A customer came in today during our big spring cleaning sale with a set of handlebars that have the worst case of toxic sweat corrosion I’ve ever seen.He uses this bike on a home trainer in his garage and had noticed that his bars were flexing quite a bit. After unwrapping the bar tape, he saw the nearly complete disintegration of the aluminum alloy caused by exposure to toxic sweat. We’ve seen this on the occasional bike, with parts literally being eaten and destroyed, but this is the worst case I’ve seen.
Aluminum was completely eaten through, kinda reminded me of those pictures you see at the dentists to scare you into flossing.
What’s the lesson? This definitely isn’t an April fool’s day joke, but if you sweat a lot you should check your handlebars regularly (once a year or so).
