I'm 6'2" not sure what my inseam is - i'll find out - says 32 on my pants... I gave my bike to a friend years ago because I didn't think I would ever ride a bike again. I used to ride a lot. I did RAGBRI several times and I rode nearly everyday. After seeing so many people with disabilities do so many things you didn't think possible I decided to start looking and I came across this site. I'm afraid to spend 1000's to find out it can't be done. I'd love to see a video of someone with similar knee ROM riding. Thanks for the help.
It can probably be figured out using geometry if you measure your upper and lower leg. Try asking the question in the road forum. There are some math geeks in there that can probably get you an answer as to what size crank arms go with a particular ROM. It has been so many years since I had done geometry I won't attempt it.
