Edelrid has worked with professional climber and big-wall legend Tommy Caldwell to develop this rope, which is ideal for big walls and demanding routes. Their ColorTec technology creates a clearly recognizable change in color between the two halves of the rope and therefore a permanent center mark. Thanks to being made on a braiding machine with 48 bobbins, the rope has a particularly fine sheath structure that offers very pleasant handling and is extremely abrasion resistant despite its thin diameter.
