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.
Crank arm length is a personal decision. However, in terms of geometry, those with longer femers (and feet) are the best candidates for a longer than normal (172.5 in general for a road bike) crank arm. You'll have to actually ride a bike with longer crank arms to find out if it works for you.
