Well, the Ergon GP2-L did the trick. No more numb fingers. So I put the bike on the trainer today and started to work on my cadence. My knee doctor (two arthroscopic surgeries for torn meniscus) warned me not to to any quad extensions or squats because of incipient arthritis. While obsessing last night I was surprised to find that my 'casual' cadence was putting more load on my knees. I was doing mid fifties. I did 40 minutes at 72 cpm (10 miles @ 15 mph on the Trek Node 1.1) and guess what went numb? This is my second seat.
It's fascinating at the variations in techniques, all of which are defended vigorously. One says tilt it forward, the other says tilt it back a bit. I did the latter and at a half hour I went numb. Actually the sit bones, the most common complaint it seems, aren't the problem; the numbness is. So, I guess I'll have to do what everyone has done and try a few more out. Sigh.
