Just swapped my chain for a new one as I hit the 1.0 mark on my chain wear thingy. This freewheel cassette has only seen 1 chain (I replaced them as a pair last time) and visually I certainly thought I would get a few more chains out of this one. But to my utmost surprise i'm skipping badly when in the bottom gear! Nothing I can do about it, new freewheel time, but just so surprised. Doesn't even look that worn. Anyone else come across this? Only lasted 1 chain and I replaced the chain soon as it hit 1.0.
