Just wanted to share this with you. I've been having a pain in my knee for the last few years, on and off, most likely because of a meniscal tear that I've never had treated
Anyway, last week I was out riding my bike and I got this knee pain in my right knee in the middle of the ride and after I got home my knee started to swell up and was very stiff. Anyway - today I went for a ride again but before I started I adjusted the hight of my seat/saddle (made it higher) so I would straighten my knees better and voila no more kneepain!
So; I just wanted to emphasize the importance of adjusting your seat. I think this is especially important if you a) have knee pains, or b) are over weight ((like me) and there for at risk of getting joint pains!).
