i too wonder about riding FG and knee recuperation....ive heard differing opinions.
im 28 and have had a series of knee injuries from playing soccer throughout my life, and about 6 months ago had anthroscopic surgery.
some people seem to think FG riding is great for getting the knees stronger and getting a smoother joint motion, but i have also heard FG is bad for the knees.
anyone with experience with both knee injuries and riding FG afterwards, i would like to hear your opinion.
PS sorry to hijack this thread, but it seems to be the direction the conversation is going.
