Next question from @trouble is about brake pads:

Q2. Has anyone seen brake pads like this before? This is my second time coming across pads that look just like this (the plastic and brake material shapes) on a road bike. Look closely; those shiny silver bits? chunks of rim! I yanked these off and replaced them on my bike with Koolstops, but only after the metal bits wore grooves into my rim, ugh #BikeCommuterCabal

Has anyone else seen alarming brake/rim/rotor conditions?

@trouble
A2. My rims are starting to feel a little concave from the wear braking over the years. I'm not sure when it'll be time to replace them, but the time is approaching. Hopefully it'll be long enough so that I can take my time finding another set of wheels/rims.

@ascentale rims can be measured for thickness to determine remaining life. However, I've never looked up how thin indicates needing replacement. Nor do I have the tools (micrometer) to do so. Calipers don't work because they need to fit over the rim's bead. At this point I'd defer to your LBS.
