World's Lightest Ski Bindings?

Update: Gear Junkie reviews these bindings here.

Starting next month, backcountry skiers in the U.S. and Canada will have the opportunity to buy a binding that’s popular in Europe’s randonee race scene. The La Sportiva RT Ski Binding is a patented free-heel binding that tips the scale at a meager 175 grams, making it officially one of the world’s lightest ways to connect a boot to a ski.

La Sportiva RT Ski bindings

La Sportiva touts the binding as a “technological innovation in the world of ultra-lightweight engineering.” Its weight is impressive, but the inclusion of toe and heel release functions makes the bindings usable beyond the randonee race fringe. The toe-release adjustment system has a release value comparable to 5-10 DIN — a first for a binding of this type, says Jonathan Lantz, president of La Sportiva North America.

Integrated crampon attachments and a three-position heel riser for touring mode are included. For racers and backcountry speed demons, this binding is light and cool, no doubt. Too bad it’ll cost you almost as much as a season pass. The RT ski binding, available in December from Backcountry.com, Bent Gate Mountaineering, and Mountaingear.com, will cost a not so ultralight $700.

Those look rad! So, are these AT bindings? That’s what I would assume, but I didn’t see any mention of actually being able to lock the heel down.

Yes, heel-lockable AT.

Is this binding have din release in heel and toe and is lateral release work?

You have the lower picture mis-named. It is actually the front part of the binding, not the rear binding piece. Also, it would be nice if you showed a picture of how the rear binding piece locked into the boot.

Chip, made that caption edit, thanks. Plus, we put these bindings to the test this winter! See our “Welcome to the Sport of ‘SkiMo’” article here.
