The easiest and fastest method to break in a new saddle is with a liquid leather dressing, such as neats-foot oil, Lexol, seal oil (a French favorite) or baseball glove oil.. These products are available from shoe stores and sporting-goods stores, and over the Internet. There are probably lots of other liquid oils that would work as well. Race Across America pioneer Lon Haldeman uses SAE 30 motor oil, but his saddles tend to wear out after only 300,000 miles or so (according to Cyclist magazine).
