Maybe worth mention that bike fit is dynamic, especially when starting with a body with limitations. Say you have some tight hamstrings, they're going to limit your flexibility and leg rotation - if you commit to improving your flexibility, as your hamstrings loosen up and strengthen the fit that you were using/accustomed to may very well need to change to accommodate the new level of flexibility. Sort of vague, general advice, I know, and consider that it's coming from someone who hasn't had a bike fit. I'm glad to hear [MENTION=489622]NiGoCo[/MENTION] getting an MRI.
