Sprenger has made the original flex irons even better. Now they flex at four different points (two points on each side), for added comfort, safety, and performance.
More security: The four links now allow movement in four directions at the same time enabling immediate release in case of an emergency.
More flexibility: Adapts perfectly to the movements that have to be made in all riding disciplines. This is the only stirrup in the world which has dual lateral flexibility thereby softening the impact on cartilage and ligaments.
More strength: Resistance against breakage has been increased by more than 30%. More comfort: Improved flexibility for easy mounting, secure whilst in motion, relieves tension in the hips, knees, ankles and calves following the movements of the foot precisely.
