I just bought a bike and the aerobars are a bit too low for me at this point in my conditioning. The stem is an 80mm, 6 degree. I have room to move forward, so would a 100mm, 17 degree bring the bars up a few cm or do I want to go to something even greater than 17 degrees? I'm thinking that the math on the 100/17* isn't really going to make that much difference at all.
