About the book: 2002 / This book is for both curious beginner equestrians and their experienced mentors. In particular, we will talk about the “gearbox” that is located in one horse vulture in such a sensitive place as its mouth. A translation as close as possible to the original source, if it does not reveal anything new to you, will at least introduce you to the assortment of iron for riding horses from the German company Hermer Sprenger. Or maybe you will simply be respected by the serious scientific and analytical approach with which the creators of iron (bits) for horses approach their work. From myself: a horse’s mouth is that same box gears, which determines whether you are driving a Mercedes or a Zaporozhets. Or in another way: people are not born tight, they are made tight. In addition to introducing horse hardware, the book briefly introduces other products of the Sprenger company - stirrups and spurs. Sincerely yours, Horse World».
