My left knee has been hurting off and on this year and it's getting worse. I was thinking of having somone check my fit on the bike. Even though I've been riding for about 20 years with no change in my bike position this knee pain is getting on my last nerve. It's on the inside of my left knee and hurts when I stand or apply hard pressure. Does anoyone know a good person to check bike posostion on the Atlanta GA area. Thanks
