Why We Like The Speed Radical Binding

Dynafit's Speed Radical Binding is a tried and true binding for backcountry skiers who want to shave ounces for speedy ascents, but don't want to give up reliability when it comes time to drop. With release values from 4-10 you'll feel confident when it comes time to ski your hard-earned line, and you'll have plenty of juice left in your legs to head back up for another quick lap should you so choose, because these uphill-hungry clamps weighing under a pound per pair. For really steep ascents, just engage the easy-to-use climbing aid using your ski pole without even skipping a beat. The step-in side towers add overall durability to the toe piece for long seasons of use, and the heel is adjustable to accommodate a range of different boot sole lengths by 12.5mm.

Great all around binding

I’ve had 3 sets of these over the last decade and they’re my favorites. From light and fast to big remote tours, they’re a great pick. Most bomber toe piece around, and the adjustable length heel will allow you to use your race boots or Quattros depending on the day. Flat touring mode is great for long days out. Great binding!

Simple tech binding that works. Step in is super easy compared to older DynaFiddles. Risers are super easy to engage.

Very happy with these bindings. I have them mounted on my Dynafit DNA skis & ski them hard on the downhill with no problems whatsoever.

These are really solid bindings and easy to use. Forget the ski breaks - the leash is just fine and will hold onto your boot in case of premature ejectulation. I get a little bit of ice buildup underneath the heel but it seems to break free with a few whacks of the ski pole.

lightweight AT bindings, easy to use. I like the multiple heel lifts.
