Our 10 Brain Coral Vertical Wall Crimps offer an excellent crimp style hold for the intermediate to advanced climber. With an incut that goes straight back to the wall, the smaller hand will have a much easier time gaining purchase. The absence of an incut makes these crimps an excellent choice for grip strength training. These crimps offer more of a challenge than the 5 Small Brain Coral Crimp. On a vertical wall, expect 5.12 feeling holds. They get challenging as the wall gets steeper as the incut is neutral.
