Sale: $149.00 - Retail: $415.00 is the high DIN version of the Railflex series bindings, designed around the needs of high intermediate to expert level skiers. The Tyrolia RFD 14 has the Speedrail adjustment, so it is one step away from being a rental/demo binding in terms of adjustability, but far above in terms of performance. The RFD 14 has a Full Diagonal Toe coupled with the popular diagonal heel release, resulting in a very safe binding at a high DIN value.
