Last season I had the luxury to ride Dynafits redesigned daily driver binding the Radical FT 2.0. This review will discuss the details of what sets this binding apart.
The binding functions like any other frameless binding on the market. The pin closes on the toe and then the heel is pressed onto the pins. The heelpiece rotates to allow a free heel for touring action. The toe has three settings, locked for touring mode, ski mode and open mode. These functions are inline with all tech bindings on the market.
The heelpiece is standard to most bindings. There is a vertical release tension, a horizontal release tension. The brakes are active until touring mode is selected and the boot is securely in the ski. The big advancement of the new heelpiece is the forward pressure adjustment. This adjustment allows the heel to accommodate for flex of the ski. The user benefits from forward pressure by having the boot always in contact with the heel pins.
The toe piece is where things get interesting. The toe piece is on a turn-table which allows a pivoting action. This feature allows the system to flex due to an increase in elastic travel. What this means for the user is the binding can accommodate for more movement due to impact. A binding that can handle sudden forces better than its predecessor translates to a lower more true release values. This benefits the user by being safer and retaining the ski to the boot.
All these techy upgrades translate to a binding that is TÜV (Technischer Überwachungsverein) certified. This is achieved through increasing the elastic travel in horizontal and vertical directions.
The negative to the pivoting toe is noticed during ascending. If the toe is not locked and in ski mode the binding will start to rotate. This rotation translates to a ski or skis turning in weird directions to the desired direction of travel. This is really a subtle negative and can be overcome by always putting the binding in walk mode before ascending.
I have not really talked about the weight of the binding. There are lighter bindings on the market. The Radical FT 2.0 does not try to compete. What it does do really well is stand up to abuse and punishment of daily skiing.
To summarize, the major advancement of this binding is the increase in elastic travel for vertical and horizontal releases. The increase in elastic travel is achieved by the turn-table toe piece and forward pressure in the heel piece. All this elastic travel increase creates a binding that is safer and more enjoyable for the user. All this allowed the binding to be TÜV certified. On the negative side this binding is slightly heavier. After weighing both sides of this binding I would personally keep skiing on it and enjoying the benefits of increased elastic travel.
