Like a steadily dripping faucet, there can be little as annoying as squeaking your way down the trail in your new saddle. At first the sound of new leather is rather gratifying; eventually it gets on your nerves. Those light colored show saddles are major culprits of saddle squeak, as the lack of natural oil that makes them light also lends to squeaky leather. Saddles usually squeak between the fender and the saddle tree.
But there's an easy, inexpensive solution that won't take up much of your time. All you need is some baby powder. This will reduce friction between layers.
