The Rottefella start binding was developed with children in mind and has been designed to give them a sense of achievement by allowing youngsters to easily operate their own bindings. The dual Manual/automatic binding entry is easy to operate with gloves or mitts and is perfect for small hands. It also gives parents two options for helping their young skiers learn to use bindings. Perfect for classic skiing in trail systems, the start binding provides great stability and control. Designed and built by Rottefella in Norway, the start binding is compatible with nnn, turnamic, and prolink boot soles from euro size 25 to 39. Requires a Rottefella start mounting plate either pre-installed on your skis or mounted separately with four screws (plates sold separately).
