New Saddle
I've tried quite a few saddles in my quest for perfection. (Maybe not perfection but simply 'better')
I tried the B-17 and though it was comfortable from the start the numbness did not go away. I thought I was going to have to give up cycling.
My wife found an article by NIOSH (National Institute for Occupational Safety and Health) on saddles related to bike messengers and bicycle police. They recommended noseless saddles and I think named a few.
After looking and researching I tried the ISM Adamo saddle. It took a while for my sits bones to adjust but the numbness went away immediately. I recommend it highly. I'm sure there are other saddles that work, but that is where I landed.
Good luck
