After 6000 miles, it feels like my saddle needs a teensy bit more tension. But I run across two problems, the first is I read that the great Sheldon Brown said don't mess with the tension bolt, leave it alone, you'll just screw up your saddle.
The second is after trying to tension it anyway (apologies to Sheldon) not only does nothing move but I lose the little wrench. And since then a few mechanics have tried to tension the saddle with no success.
Is this little operation typically such a challenge?
