I have several B17s. The one with the most miles on it has just over 5100 miles. I am a clyde and put a lot of stress on the saddle. Recently, I had been having problems with chafing in the soft tissue area, to the degree I could hardly ride on it. I did the following two things: 1- lowered the saddle a tiny bit (probably about 1/4 inch) 2- tensioned the saddle (probably about 1/4 turn). These fixed my saddle problems. I'm not sure if one or the other did it, or if they fixed my problems in tandem, but I'm no longer having saddle issues. And, no, my saddle didn't appear to be sagging and I have NONE of the infamous sitbone indents.

I never ride it wet (other than sweat), as it's covered when it's raining. I've only used Snoseal on it 2x.

By the way, I used needle nose pliars to tension the saddle - no need to buy a special wrench.
