Admittedly, it's been a while since I did any regular riding, about six weeks. Off and on I have had a bit of an issue with pain on the inner back side of my knee. Only while riding the 'bent, never on my DF.
I have paid as close attention as I can to attempt to achieve the same extension for my legs between the two bikes. I use the same crank length, with the only difference there being the pedals.
The issue presented about 8 miles into a 16 miler (I cut short) and feels a whole lot like an overuse injury...except that I haven't been riding. I am familiar with ITB pain, and front and back of knee issues from "seat height" but cannot seem to get a grip on this situation. Even when I was riding on a regular basis it was vary between the tendon across the back inside side of the knee and the joint itself, but only on the ligaments on the inside.
What should I be looking into, if anything, to help me get some comfort from this recurring issue?
