For conversion to 9-speed, they're not needed, but the original poster
also mentioned that he wanted to upgrade to a triple in front.
The O.P. could save a lot of money by going to a wide range cassette and
leaving the cranks alone. This would require a new rear derailer, but
derailers are cheap. He could get much lower gearing than he or she has
now without changing the cranks. Going from a 42 to a 38 tooth small
chainring would also help, again at a much lower cost than going for a
triple.
