The Radical FT binding has set the standard for freeride tech bindings. If you are above average in size or just love slaying big lines while watching your uphill weight, the Radical FT was made for you. Featuring a shock-absorbing carbon plate and release values that crank up to 12, these bindings are built to take some abuse. But they tip the scales at only 603 grams (21.3 ounces) each, roughly half the weight of your average non-tech alpine touring binding.
Carbon plate that runs toe to heel provides additional torsional rigidity to fatter freeride skis.
Heel piece adjusts a full 25mm forward and back, helping your mount adapt to a 3 mondo-size range of boots.
Brakes come in 110mm and 130mm widths, and feature a glide plate to help reduce boot sole friction for a smoother lateral release.
Vertical (forward) and lateral release values are adjustable from 5-12, letting you dial into your skiing style.
Speed Step climbing bar offers 2 riser heights in addition to flat, using the Radical flip design which can be operated with a ski pole on the move.
New Power Towers on the toe piece protects from side-impact-induced pre-release while easing your step in.
Lift plates under the toe and heel spread power across a wide surface area of your ski, improving stability and control.
Fits Dynafit ski crampons perfectly with a newly designed toe piece slot that is easier to slide in and out.
Radical FT vs Radical ST
The FT features a full length carbon plate that adds torsional rigidity and features an automatic shock absorber. Under serious flex, such as big landing, the locking mechanism will engage which turns the rear rubber pieces into dampeners that will stiffen your ski. A more natural flex will reappear after you stick the landing. The FT release value range is also higher at 5-12 compared to the ST version at 4-10, and the lift plates are slightly wider to accommodate fatter skis. When it comes to grams, you are adding 57 each with the FT, or 2.0 ounces per ski.
Radical FT vs Vertical FT
As noted in our Dynafit Radical vs Vertical article, the Radical / Vertical distinctions are many. The toe piece side towers on the Radicals are easier to step into and provide some impact protection, while the heel piece features Speed Step risers instead of requiring binding rotation to adjust your heel height. While the release values go to 12 on both, the carbon connection plate on the Radicals has a shock absorber to help with those big airs. These features come at a cost of $50 and an additional 60-70 grams per binding, depending on the brake sizes involved, over the Vertical FT.
I recently picked up this pair of Radicals 2nd hand for my daughter. As you can see, one heel has been replaced with a newer version (what vintage is the newer one?), but BOTH heel pieces rotate when in uphill mode when in step 1. Frustrating. Will the $30 Radical Antitwist Locks do the trick, as compared to the more expensive Speed Antitwist Base units? Does an in-store purchase of the Radical Antitwist Lock include installation?
Hey Chris! Depends on the exact boots you're trying to accommodate as each boot's mondo sizing corresponds with a different length. Generally the rule of thumb is that a boot increases 10mm in length for every size you go up which means this binding has 2.5 sizes worth of usable range if you mount it correctly. All the nitty gritty details are found under the "Specs" tab of this page.
Hi ng224, yes you can mount it without the front half of the connector plate that comes out of the toe piece. The baseplate under the toe is a separate piece that you would still mount. There is a gap at the back of that baseplate that could fill with snow; you might rather use ST toe plates instead.
Assuming these are the new version with forward pressure, what is the heel gap that should be used? Is it the standard 5.5mm, or should there be a smaller gap? I've read some conflicting info elsewhere on the interwebs.
Hi BPQ. Yes these are all the latest edition with the heel springs. I'm not sure forward pressure is the right term, but they slide backwards if your boot collides with the housing during ski flex. The gap is still the standard 5.5mm.
Love how stout they are--but clean your boot soles and clear of snow for pete's sake! I had quite the day at Alpental last year popping out of my bindings every two seconds with just enough pow to keep the breaks from working. Not everyday can be perfect.
