The TLT Speedfit is a versatile ski touring binding for Speed Tourers. This binding spare part only includes the binding heel unit including screws. Since adjustments are not only dependent on the type of binding and boot, but also significantly on the type of skier, these are only to be carried out by an authorized professional who can test adjustments with the aid of an appropriate measurement device. Mounting and adjustments done by unauthorized personnel are at the risk of the user and may lead to termination of the warranty. Changes in adjustments that were recommended by authorized personnel may result in a risk of injury. Please avoid any unauthorized changes in order to maintain the safety features of your ski binding. Any necessary changes are only to be performed by authorized specialty dealers. An improper adjustment, change or repair can increase the risk of injury.
