No, no popping at all that I can hear or feel when cycling. Cycling is the best thing ever for my knees; no pain during or after. Actually, the popping and pain from weight bearing movement (work) has greatly diminished since treatment with prescription NSAIDS and steroid injections. It's about time for another shot in a week or two. Cycling and weight loss gets a lot of the credit as well though. I do have a knee replacement in my future I'm sure, trying to make to into retirement first. Of course everybody's mileage will vary.
