Thought as much. Found "1079" on the front derailleur. The scale I used was a very cheap luggage scale, so maybe not all that reliable. But as long as it gives me light bikes I'm not complaining.

Thanks. I'm sure I have an Eco or two, but finding one without a hanger might prove to be a challenge. Speaking of which, I may have a Challenger that would would be a nice upgrade.

I cleaned the pedals this afternoon, and now they not only spin smoothly but look almost new, too. I am quite happy with them.
