Taking a cue from software companies, Dynafit is now appending version numbers to its bindings. We recommend upgrading to the latest version of the Radical ST if it’s compatible with your operating system. The recommendation is due to release and retention improvements that move the tech binding a step closer to its alpine brethren. With 10mm of spring-loaded heel travel and a toe that pivots laterally, the 2.0 has a smoother release while being more resistant to pre-release. In fact, the binding is now DIN certified.
Borrowed from the innovative Beast binding, the pivoting toe works in conjunction with the rotating heel to provide more reliable lateral release. The design also enables the absorption of side impacts without pre-releasing, since the boot can be displaced several millimeters and still return to center, much like an alpine binding. In addition, the spring loaded heel piece shifts backwards as the ski flexes, which helps the binding maintain its release characteristics under heavy load. This extra elasticity makes the 2.0 a better crossover resort binding than the Radical ST. In addition, the binding appears to be dipped in gold to make it a better hedge against inflation.
- Newly certified by TÜV to the DIN specification for binding retention and release.
- Radical climbing flaps let you choose from two riser heights in addition to a flat-on-ski option.
- Proven Dynafit Radical toe lock lets you select between unlocked ski and locked uphill modes.
- New wider baseplates and mounting pattern allow for greater power transfer to the ski.
- Reduced heel pin height puts your closer to the ski and normalizes unnatural ramp angle.
- Forged aluminum roof on the heel piece is stronger and attached more securely to the housing.
- Heel pieces slide backward up to 10mm to maintain consistent release while the ski is flexed.
- Toe piece pivots laterally to work in conjunction with the rotating heel to provide a smooth release.
- The binding can absorb sideways impact forces and still return to center due to the pivoting toe.
- Anti-friction devices on the brake platform prevent unexpected increases in release values.
Radical ST 2.0 vs Radical ST
The primary difference between the ST 2.0 and the 1.0 is the addition of a rotational mechanism under the toe piece. This works in conjunction with the heel piece to provide smoother lateral releases while being more resistant to pre-release due to side impacts. There is also a new screw-hole pattern and larger base plates to spread power across a wider area. Slightly lowered heel pins, stronger climbing plates, and a shiny gold coating complete the checklist of differences.
Radical ST 2.0 vs Radical FT 2.0
The 2.0 versions of the Radical ST & FT mirror the differences found in the original versions. For starters, the FT versions have stronger heel springs, increasing the maximum release value to 12 versus 10 on the ST models. In addition, the FT 2.0 features wider baseplates made of aluminum for better stability and power transfer than the plastic ST plates. Those changes come at a cost of $100 and approximately 35 grams.

Questions & Reviews
I just mounted a Radical 2.0 / Rotation 12
I have seen that you recommend a 0.1mm gap. I assume that is from the point I pinpoint with the red arrow in one of the pictures
I know what the big nub on the back is for and how to adjust it but the small screw above that adjusts the "scale on the top of the first picture. How shall that be tuned? Is that some equivalent to the bias pressure in ordinary bindings?
No real pre-releases to speak of - even with plenty of ski patrol work with heavy toboggans (with heavier people loaded) down steep runs. And i'm a bigger guy to begin with (210 lbs). Of the few wrecks i've had where they needed to release they did.
On the tour side of things ... 100%. No releases, no problems with ice, no problems with brakes ... super solid.
I'd recommend these bindings to anyone.
