Hello Mark,
We have three trees: the first classics, made of wood, the second called Dynamick®, made of composite materials (Carbon Kevlar and fiberglass), and the third ones, which are also Dynamick®, but realized for morphologies Feminine and for the saddle Mademoiselle.
These different approaches are related to the rider's morphology and the rigidity of the tree, which generate feeling and comfort with the rider, thus marking a difference in the transmission of information from the rider to his horse.
Thank you for your question!
Team CWD
