Have you tried contacting a customer service person at Seven directly and posing these questions to them. They might be able to help. I'm 5'0 and I went to the 165 cranks and I have a triple because its hilly where I live. I love my granny. Most of these things are fit and personal preference. There are a bunch of photos at hubbub.com. in the photo gallery. They also might be able to answer some questions for you. Worth a shot.
