Evaluating Saddles
Saddles are OK as long as they're not broken or ripped.
To check for breaks, flip the saddle over and look at the two metal rails. They should be solid. Grab each one and tug up and down like you're trying to pull it out of the saddle. If anything moves, the saddle is broken where the rail connects to the plastic shell.
Get a good look at the plastic shell from the bottom, and if there are any cracks, it's broken. Try to flex the saddle a bit, and make sure you don't find any cracks that way.
If the saddle has springs underneath, make sure that all of the bolts and nuts holding everything together are there. If anything is missing, the saddle is broken.
If the saddle has a fabric or leather covering, and there are any rips anywhere on it, it also goes into the "bad" pile.
