I know this must already have been covered someplace, and I did try the search feature before posting, I swear.

I have a Sram Dual Drive and 11/32 cassette on my new Xootr Swift. The pedaling feels small, so I think what I want is longer crank arms.

Never having done this much customization on a bike before (and being new to learning about drive trains in this much detail), I have two questions:

1. Does my conclusion (that I need longer crank arms) make sense?
2. What else don't I know enough to ask?

Thanks much in advance. If you're interested, my Swift customization thread is here, and bike specs are here.
