The latest innovation from Salomon in terms of classic bindings, the Prolink Shift Pro Classic features an adjustment system that allows you to change its position. This increasingly common type of system offers the possibility of changing the ski's behavior. The binding can be moved forward for greater grip, or backward for greater glide. It can only be fitted to skis with Salomon or Atomic PSP plates. Operation is simple: simply lift the binding's engagement cover and push the push-button underneath to the side. To lock it in place, simply lower the binding cover and the system locks automatically. This gives you the opportunity to adapt the skis to the skier's physical or technical level in terms of grip, particularly in tricky sections. However, you must take off your skis for any manipulation. Technically, we find all the technical arguments of Prolink bindings, with very low interfaces that promote proximity to the ski, and two Prolink guide rails that stabilize the foot laterally when the ski is put down. The Flex 85 is designed to optimize foot roll in classic style. A very good binding that allows you to adjust ski behavior with ease and precision. This description is an automatic translation.
