The Dynafit Speed Superlite 2.0 was recommended to me as the lightest weight backcountry binding available. At 175g per binding its super light, and with 2 riser settings it is featured enough for touring. I run it without a brake and mounted it directly to the ski, (Dynastar Vertical Eagle 1100g), which was a mistake as I want to use 2 boots for this awesome, uber light set up. I'm thinking of buying the Superlite Adjustment Plate and remounting so that I have versatility with boot selection. Anyway, I've used this set up as a daily ski hill trainer, skied it in Pearl Basin and even ran it in the Aspen Power of 4 against people on race skis! Amazing versatility is the hallmark of this nifty little binding.
I have two pairs of these bindings. For weight savings I wouldn't go anywhere else. Of course, I always get a little nervous about going TOO light and having something that isn't robust and durable enough--I have not found this to be the case with the superlite. I have one on a pair of big powder skis and one on some rando-twigs and I don't hesitate to ski either like I want to.
With the revolution in ski touring gear and the insane amount of new binding flooding the market I think there is a risk of some bindings being too light and wearing out. Thats why Dynafit makes me feel confident--they have been doing it right for over 30 years. I might think twice about a first or second gen binding that is this light but not with these. Over the past two seasons I haven't had any issues and when I step in the click is just as crisp as ever.
The Speed Superlite is my go-to binding for all that is backcountry. The Superlite is everything you need and nothing you don't. I'm 6'4", 180Lbs, and I appreciate light gear that doesn't sacrifice downhill performance. I've found this binding to be secure, durable, and able to do it all. I run my set up with no brakes, but even with the brakes this binding is superlite. This binding can be used as a daily driver, is light enough for a race setup, and will standup to high speeds and committing lines. If you like to ski hard and also keep your setup light, look no further because this is the binding for you.
