Seat is stamped 17.5 but measures 18″, flaps measure 13.5″ bar to bottom and 14.5″ across (2.5 long/forward flaps) the front gullet measures 4 1/2″- generous medium (most Butets measure 4″ for medium so this is close to a medium/wide in a Butet tree).
2006 model. This saddle has the deeper C seat. The leather on this is very soft and supple and this has soft and squishy knee pads. There are both front + back blocks on this saddle. It has been very well maintained and conditioned and has no cracking and no loose stitching and not even a prior name plate was put on. Seat does have some water spots (see picture). If you are tall both hip to knee and long from your knee to you ankle you may want to try this.
* Included: Thick Gold Butet Saddle Cover
