After last week’s Thursday night ride, before which I put a new chain on the Lev and noticed a bit of skipping, I replaced the cassette too. Even better, I had enough odd cogs to do it without buying anything. Better ratios now, too (14-16-19-23-28-32, v. the old 14-18-21-24-28-32). The interesting thing is, last week it was only skipping in the 24 cog. I know now, from this cassette and the last, that it is the one which wears quickest.

Gears, a mixed blessing.
