My B17 is now sagging from riding in the rain. I never left it in the rain, but I rode it, uncovered, in the rain. After a couple of years, it's not so great.
I've taken it off the bike for now. I'll probably lace the sides to tighten it back up.
I loved that saddle, and I pushed Brooks to anybody that would listen. Now I'm wondering if leather saddles are a good idea for me.
