That looks way better. Feels better too, huh?

One thing I notice is the extreme bend in your knee in the up position. You might try sneaking the seat post up a little at a time. Us old guys need to reduce the joint angles as much as possible for comfort.

Cycling shoes? Not for me- anymore. I had ridden for several years clipped in and with toe clips. I was under the impression it was more efficient. Then I read an opinion
(I think it was on the Rivendell website) on riding "bare" and thought, what the heck- I'm gonna try it. It's been 3 or 4 years now, and I don't notice any loss in efficiency. I can maintain the same cadence, and the same speed but more comfortably. I can climb as good as ever- plus I have the ability to move my feet around on the pedals when my numb feet and joints tell me it's time for a different position. YMMV
