I have 2 cranksets, minus the chainrings, in my parts bin. It was cheaper to buy the whole crankset with the chainrings I wanted than to buy the individual chainrings.

A lot of the touring bikes in our family, including mine, are set up with 9-speed 44/32/22 cranksets with an 11-34 cassette. We have one hold out that runs a 48/36/26 with an 11-34. I'll put a 24 tooth small chainring on before a tour this summer; but I'll bet she will ask about a 44/32/22 when we return. There will be a lot of climbing.
