Auto rotation sucks! I sheared the original pin and the first set of replacements they sent. The last pair has held. But just having this occur on all of my Dynafit bindings (except my FT-12's) has helped me move onto race styles bindings (lighter and no heel rotation to rotate). I've had a variation of this binding on several different skis over the last 15 years, and while they do what they do extremely well, I think it's worth the increased money and decreased options to pick up a race binding. That having been said, they are way better than any non-tech binding.

Great binding for the price. I also broke the anti rotation pin. local Dyna dealer just pulled them out. Haven't had any issues yet.

Adjustability is nice. Climbing bars work great.

I've used these bindings exclusively for the past 2 years.

They have seen everything from resort skiing to midwinter tours to spring steeps like the grand teton.

They work pretty well, I have had 3 issues however.
1) I have them mounted such that I am near the back of the adjustment track(so my wife and I can share the same mount) and this can cause snow buildup under the heel. This then compresses into ice and makes it difficult to rotate the heel into downhill mode.
2) I broke the anti rotation pins, but they don't rotate on the fly for me much, so not a huge deal.
3) Just before my grand teton trip the adjustment track stopped keeping the heel in the right place(it would adjust looser on the course of a tour, requiring on the fly adjustments with a ice axe or pozidrive if you have one). Good thing was dynafit was quick with a replacement adjustment track and I was able to be up and running in time for the grand.

I would give it 3.5 stars if I could, but will round up since other than these issues it has been a good binding and reasonably light weight.

When I don't need brakes for liability- which is rare given that amount I ski on the same pair of skis on the East Coast- having the speed radicals underfoot is awesome. Not quite as stable as some of the bulkier bindings, but for light skiing or big boards in powder, there is almost no difference. Hopefully Dynafit can make the heel levers a bit more reliable, but otherwise a perfect first or fifth pair of Dynafits. Could probably swap the heels onto the other radicals plates if necessary.

Have this binding on my Dynafit Broad Peaks and skied this setup from powder to steeps to 7000m peaks (about 30 days and lots of vert). I also used it a lot with ski crampons. Overall, everything works really well, ski crampons too. I like not having to bend down for switching the heel lifts.

Only 4 stars since on occasion during a traversing skinning on hard snow the heel flips to the ski position. Would buy again though.

Sounds like you sheared the pin designed to prevent this rotation. These are replaceable fairly easily by unscrewing the release value adjuster (I use a quarter), removing the spring and yellow cap, pulling off the heel housing, possibly moving the heel fore or aft to access the pin, and then swapping it.

That is if you have the (right) pin :)

I think that pin is useless/not strong enough if it shears on a second day. However, this hasn't stopped me from using the binding and being happy with it ;)

Good news Stano, 2014/15 Speed Radicals are now shipping with an anti-twist device that gets mounted under the heel piece. Definitely worth the extra 12 grams.
