Ulla's comments: wide treads for more ankle support, incredibly easy to change.
New Stirrup MG made from Magnesium with an option of 2 metal treads, one light and one heavy, which are interchangeable thanks to a patented quick change system. With the light tread the stirrup weighs 400gr., with the heavy tread 650gr. In the future it will be offered also with treads covered with rubber (one heavy and one light)
Colour: silver - black
