As Sam knows, I'm building the vintage Nishiki (born-on date 1975 or so) into a single-speed cross bike. More on that forthcoming!
Having removed the outer ring I needed to clean the old cheapskate FSA chainset from the original Cervelo tri bike. I'm fresh out of my favorite Finish Line Citrus degreaser so I turned to what I had lying around: Five-Hour Energy.
A disturbing yet amusing lesson: Five-Hour Energy on a toothbrush does about as good a job as one needs degreasing a 6-year-old chainset.
(Caveat: I did not compare Five-Hour Energy with anything else. It could well be that water on a toothbrush would have done the same thing.)
