Update
** My left hand and elbow were numb for a few days. I decided to lay off the bike for a few days.
**I moved the seat up 20mm. That works out to half way forward. I went for a 15 mile ride 6 days after initial numbness ride. Hands felt good. But I had a slight right knee pain. The pain was on the top of the knee. After the ride I was fine.
** I slide the seat back 10mm and went for an 18mile ride this morning. Less pain in the right knee and it was more in the center of the knee. Hands felt fine. Knee was fine after the ride.
I'm going for a slightly longer ride tomorrow morning. Will report back.
I'm riding gloveless. I ordered a couple of pairs from Amazon and I'll see which pair's padding doesn't impinge my ulnar nerve.
Thanks for all the advise.
