I haven't posted any CL police stuff, but for weeks I've been watching this guy try to sell his nice vintage steel bike with downtube shifters, claiming it's a "six speed" made of "chrome mooly." Finally, I couldn't stand it, and gently emailed him to suggest he recheck that speed count, explaining how to calculate it accurately. He was absolutely irrate of course, on the first reply, but I persisted (why, I don't know). When I explained that he'd misspelled chromoly and pointed him to Sheldon Brown to determine speeds on the bike, he actually emailed me back and thanked me. It's now posted as a 12 speed, with chromoly spelled correctly. Bet he sells it faster that way .

Won't do it again, but it really bugged me every time I saw that ad.
