So I have my bike setup on the trainer getting it ready for a race this weekend and I reach over it to grab something. As I am doing this my nose comes 1/2 inch away from my saddle and I suddenly smell the accumulation of several weeks worth of crotch sweat. It takes me a second to realize what I am smelling before my stomach turns a bit. I don’t pee on the bike and the saddle is only a few weeks old, so I can’t imagine what nastiness exists on some of the more “weathered” saddles out there.
Always know where your nose is in relation to your saddle at all times!
