I get occasional inflammationat the insertion of the semimembranosus muscle on the tibia after high volume weeks (i am a roadie who rides around 275-325mpw). The issue always resolves itself after a few easy days but i want to find the underlying instigator. Assuming proper saddle height, AKA not too high, which mine is not, people argue that moving the cleats aft will help with the issue. My cleats are right in the middle, when u switch to a more aft cleat position i notice my gastroc's are much tighter than normal. In general i am just curious to see what some people with a fitting background have to say, i am pretty well versed in anatomy so you can use big words.
