AC620 The Arco AluPro stirrup is made of a certified high-grade aluminium material and has been designed to have a maximum weight of 310 g per piece which is much lower than the average weight of standard steel stirrups. The stirrup pad with its practical long holes (avoiding dirt accumulations between boot sole and tread) and its lateral recesses, as well as the “open” and fashionable design of the stirrup bow provide for an additional weight reduction. The extra-large stirrup pad is inclined towards the rider’s foot (5° angle), permitting the rider to achieve an optimum leg position and to sit in perfect balance, while relieving tension in his hips, knees and ankles, which is indispensable for a comfortable and secure ride. The special grip effect of the tread surface even enhances the stability of the foot position, making the rider feel extremely secure, like being one with his stirrup. We have added 4 rivets with screw thread for a stronger grip effect. The colouring of the stirrup bow by means of anodization provides the product with an effective corrosion protection and also permits us to offer this product in a wide range of different colours. The bright aluminium surface of the pad, making a nice colour contrast to the upper part of the stirrup, is obtained by a special polishing procedure. Developed, designed and manufactured in Italy.
