    What do I adjust?

    Not sure if I need a body mechanic or a bike mechanic. Right knee about one inch closer to top bar, often touching it. Also noticed problem on just retired mtn. bike but ignored as new bike was on the way. Had to remove stuff bag hanging under top bar as shorts rubbing it causing unnecessay wear.
    Confirmed seat centered, played with cleats and seat up/down. Did not have this problem when I stopped riding 5,000 mi per year 23 years ago.
    Any suggestions?

    If it's a problem on two bikes i'd say it's a body problem. Or right cleat needs change.

    The average modern triple crank places the right pedal a substantially greater distance from the center of the bike than the left pedal (and compared to TA and other older-design triple cranks), so if you're leaning that knee inward to compensate, that could be at least part of the explanation. You could try a thin lengthwise section of the left side of a shoe liner under the existing liner in your right shoe (and pull it out immediately if you feel any knee twinge as a consequence).

    I'd consider a Retul fitting. I had a similar issue, although not as bad as you describe, and it was discovered that shims under my righ cleat were needed. No problems since.

    +1 I have shims under my left cleat to keep my knee in proper alignment. Was done during my bike fit 5 years ago.

    I tried something different. I took my shims out and moved the cleat forward. I think it feels a lot better. YMMV

    The knee should only move in a vertical plane during the pedal stroke. If the knee moves horizontally during the stroke, the seat height might be a problem. Saddle height that is too low can cause lateral movement of the knee. There is a lot of bike fitting info on the net. Find out how to adjust seat height, the saddle fore and aft position, and the reach (using stem length). This will give you the basic fit.

    A professional fit might help. The best fitters are physical therapists who specialize in bike fitting versus some bike shop employee who has been through a one day fitting session.
