This 17.5" Equipe saddle has a medium tree and a long flap. It is extremely comfortable and horses love the flexibility and lightness of the carbon tree! I also have this same exact saddle in a medium wide tree. The EK 26 retails for $5450. Make me an offer!!!From a combination between the spirit of craftsmanship and Selleria Equipe’s vocation for innovation, is born the E-Carbon line of saddles, an example of the supreme excellence of Italian craft and a veritable gem in cutting-edge technology.The core of E-Carbon saddles is the laminar saddle tree in carbon and three-composite fibres, which ensure their excellent technical performance and which can be personalised in shape and thickness, as well as being equipped with the extremely effective D.S.B. (Damping System EQ Bridge) shock-absorbing system. Machined with special high-tech equipment that defines its lines, the saddle tree (patent pending) can boast a truly supreme manufacturing precision. Furthermore, carbon is a material well known for the advantages it affords in constructive precision, lightness and sturdiness. These are mechanical performances that are further enhanced by diversification in the material composition of the saddle tree in its two front and rear sections to comply with the two respective requisites of rigidness and flexibility, and by the innovative shock-absorbing system that improves comfort and performance, to the benefit of that very special “tuning” between horse and rider.
