I started reading about the 16T sprocket here, waited a week or so and decided to order it. About a day later I noticed folks posting that their orders were back-ordered. Guess what, so is mine! Somewhere in Sprocketville there is a production manager who is scratching his head wondering what happened. Of course, once they ramp up production to meet demand, everyone on the forum will already have one and the already low price will drop to $1.50 as the shelves fill up. Gosh, my economics professor was right - I would use that stuff one day!
