Two of the bikes in my collection one a Wabi Classic is sporting a Rivet Independance and originally was what Rivet calls chestnut color . The other bike a Mission Bicycles Sutro has a Gilles Berthoud Aspin installed that originally was what is referred to as natural color. Now hundreds of miles and many Obenauf’s smears later I would say they each are a variation of brown. I am not complaining they are aging beautifully in my opinion from the finishes to the way the leather is softening meeting perhaps even exceeding my expectations if they last long enough.
To illustrate the the wearing slash breaking in effects I’ve included some pictures that can put it across much better than I can explain it. the two pictures below are the Gilles Berthoud Aspin. One picture a new unit picture ripped straight from the Gilles Berthoud website showing what is meant by “Natural” and mine was exactly as the picture when I received it. The other showing mine as it looks today. I really like the way an uncolored saddle finish changes. The finish wears uniquely on every saddle no two are alike! Also notice the slight differences in the shape between the pictures as this is the leather softening slash breaking in to fit my anatomy. The shiny effect well that’s all from using Obenauf’s on it. The Aspin has become a really comfortable perch in my opinion.
