FWIW, out of curiosity the other day, I counted the teeth on my old Murray cruiser. It has 46-19. Speaking of old Murray, he sure does look funny these days. Even with the seatpost and stem at maximum extension, my knees were still in my chest and handlebar too low, so I got $4 seatpost and stem extensions. The regular bar swept back so far my knees were still almost hitting my hands and I felt so upright I was almost leaning back, so I replaced it with the leftover riser bar from my hybrid, complete with bar ends. Talk about your Frankensteins! On the other hand, I doubt any thief with a vestige of self-respect would want to be seen riding him, so I probably don't even need to lock him up when I go to the store.
Regards,
Raymond
