The Dynafit Speed Superlite binding is a patented compromise between lightness and safety. Also known as the Race Adjust binding, the Superlite features the ability to customize lateral and vertical release values while keeping the weight to a minimum. This binding is for those who like to race to the top quickly but don't want to compromise on safety. Checklist highlights are many:
Adjust lateral and vertical release values with a single screw to customize for your weight and skiing preferences.
Features the standard Dynafit toe locking mechanism with both skiing and locked modes.
Additional riser plate versus the Low Tech Race offers a second option for those steep climbs.
Made with forged aluminum and high-strength plastic to endure the grind of everyday touring.
Optional adjustment plates can be installed under the toe and heel to give boot sole length flexibility.
Same 4 hole drill pattern as the Low Tech Race binding toe, though the rear heel screw is further back.
Racers will like this binding for reasons described in our article Dynafit Race Bindings. Non-racers beware, there are a few gotchas that come with such an amazingly light binding. The heel piece has no fore/aft adjustment, so unless you add the optional adjustment plate, make sure to get a precision mount done by a professional to match your boot or you may experience some pre-release. There is also no "flat" riser setting, as the risers drop over the heel pins. The binding is only designed to rotate as part of the release mechanism.
Speed Superlite vs Low Tech Race
Low Tech Racers will have a weight advantage over Superliters of 75 grams (2.6oz) per binding. The Superlites, however, will save you $250 and let you customize the release values for your weight and ability. You could also be standing taller on the steep climbs with an additional riser option.
Speed Superlite vs Speed Radical
Speed Radical users will enjoy the flexibilty of a flat riser setting and a quiver of boots with a full 25mm of fore/aft heel adjustment. They may also brag about the Power Towers in their toe pieces which ease entry and protect from side impacts. But skiers with Superlites might not hear them as they are lugging 161 fewer grams (5.7oz) uphill and are already out of earshot.
Hey Michael! That's a huge mountaineering ski and definitely on the very upper limit of what this binding is probably really capable of. If it's not a relatively soft or really lightweight ski, I wouldn't mount this binding to that ski. Because of that fact, your boot selection is going to play a super important role in how this binding performs. With boots less than 1200g, you're probably fine (as long as the ski is soft or extremely light), but boots with more brute strength (this is a big generalization, but basically anything over about 1400g per boot) would likely overpower the binding.
I had my Speed Superlite bindings mounted at a local shop here in Boise. I notice that when I step into the binding there is a slight amount of play in the heal between the boot and binding. Is this typical?
I agree with the other reviewers regarding this binding being a good price at a great weight. It's my new standard for price and weight and makes my Dynafit Vertical ST's seem too overbuilt. I've used it with Aliens on Cho Oyu skis for touring and skimo racing. One caveat to mention for skimo racing is that the second taller riser can get in the way when fumbling at transitions. I have found that riser sometime useful on steep skintacks while touring but I wouldn't miss it if it were gone.
The ultimate combination of weight, performance, features and price for a serious touring binding!
Assuming you aren't dropping cliffs or using this binding inbounds, I find that it offers plenty of performance for fairly aggressive skiing on a relatively large ski (184cm 99mm underfoot dynafit denali). The weight is incredibly low (1/3 of a radical FT) for the amount of performance it provides. I have not yet had a pre-release nor have I crashed and tested its release capabilities (but it is comforting to know it CAN release unlike the low tech race).
I was worried about the lack of a flat tour mode but having high-articulation boots (TLT5 for me) makes it barely noticeable. In fact I find the lower of the 2 touring positions to be wonderful on low-angle skin tracks where the middle setting on a conventional dynafit binding would be a little high. The higher touring position works great on all but the steepest of skin tracks. Not having to ever rotate the heel during any transitions is very nice (just flip the heel lifter up/down and go!)
The extra heel lifter, releasability and $250 savings (and likely greater durability) for a mere 75gram weight penalty over the Low Tech Race makes it a great buy for all but the serious racer.
Only minor downside I have found thus far is the toe lever is harder to lock using your ski poles while standing up (being lazy and not wanting to bend down) than my old Vertical FT toe levers.
Contrary to Patrick's comment about leashes, I was easily able to attach a small, homemade leash to the toe pieces.
I have less than 10 days on these bindings so far so I cannot yet comment on their long-term durability but have not experienced any issues thus far.
Overall this is a great binding that I highly recommend and plan to buy again for my next pair of skis!
