I have this saddle and LOVE love love it. The adjustments are super fast and easy (I just hope I don’t lose the little wrench LOL!) and the tree has a ten year warranty. It seems very solid - I’m not terribly concerned about it being “fragile.” As to the leather wearing, I can’t say yet. So far after about two dozen rides it appears to be breaking in very nicely. No more wear than I’d expect. I oiled everything up very well (and it’s darkened to a lovely deep caramel color) before I rode in it the first time and plan on doing careful maintenance over the time I have it. I also have the calfskin leathers per their recommendation. Possibly they’ll release this saddle in their buffalo leather someday, if it proves to be popular.
Overall I’d give this one two thumbs up.
