Back to the baseball glove, we can estimate the force absorbed by a glove (catcher's, first baseman's, or whatever) based on the impulse versus change in momentum (this is just first-year physics), and compare that estimate to my estimate (post 25 of this thread) of the tension in the skin of a saddle holding up a rider. The impulse is the total force over time required to change the speed of the ball. Suppose the baseball ways 150 grams, is flying 100 mph, and the glove stops it within ľ second after initial impact. that time is my guess - I'm sure it is nowhere near as long as a second, and I really doubt (from my scientific study of playing catch when I was in grade school) its less than 1/10 second. Anyway, solving for teh force I get about 25#, which is not significantly fatiguing for the catching arm of a trained ball player.

Recall the saddle strip or membrane sags at an angle of about 5 degrees or less. At 5 degrees, the tension is divided by the sine of the sag angle, to multiply my 200# by 1/0.087=11.5, so my 200# causes a tension around 2300#. If I have not screwed this up, that's about 100 times more force in a bike saddle than a first-baseman's or third basemen's glove stopping a hot ball. No comparison between the stress in a baseball glove versus that in a bicycle saddle!

Softening/conditioning products intended for baseball gloves are not fully compatible with leather bicycle saddles!
