Today was a metric century - really ended up being more like 68 miles.
The new stem made a world of difference, I did not get my low back pain, my position was better in the saddle so my butt was not too sore and my right fore arm did not ache. I thyink we have a winner. In any event the women who runs these rides also is the store manager for one of the LBS, she said to bring the bike over to her house this after noon and she will see if any other changes are needed. She really liked the Sella anatomica saddle , for this ride so did I.
