I dug into the rear wheel - to inspect the brakes, bearings, etc. As expected, it was a mess - grease, dirt, brake dust, etc. So, I started carefully disassembling and cleaning the parts. Well, I thought I was being careful - but I missed these two. They were just laying there with the other pieces - and I didn't see where they fell from. And, I've gone through manuals/exploded views and parts lists (with pics) and can't find them.
Actually, I'm not even "them" is accurate - it could be an "it" that was torn in two. But, they are oddly similar to have ripped.
