Exploding Dynafit Radical Heels
Anyone else have this issue? 2 heel pieces in 2 seasons, fully split in half. Never hucking any bigger than 15 feet, or skiing inbounds on them. I've never even released from them besides last week when it failed on a mellow transition to a frozen lake. 1st time I saw it coming unglued so the above didn't happen first.
Warranty has been great - but do I really need to ski with an extra heel in my pack? Bad batch of radical heels I haven't heard of?Drive slow, homie.

Soft ski big guy? On a softer ski you can cause the pins to bottom out when you flex the ski and put extra force on the heel piece.

That's a thought. What's the fix? Heel spacing is spot on as per the dynafit indicator thingy.

Do you have the version with or without the extra rib? Non-rib is the one being recalled.
I had this happen on my first gen Speed Radical heel pieces after 3 seasons of use, both cracked and split within days of each other. I also saw my friend's first gen Radical FT heel piece split in half after he hit it with the tip of his other ski. In my assessment it's a design flaw / vulnerability of the material and process. Crack propagation on that heelpiece barrel leads to instant failure.
Look how they fixed it on the Radical 2.0! Between that and the top plate failures, they really bombed on the heelpiece design. They should just offer the Radical 1.0 toe with Speed Classic heelpiece and discontinue the current radical speed heelpiece._______________________________________________

Vertical heelpieces is my solution. I run rad toes and ft12 heels. I saw too many broken radical heels come back when I worked at the shop.

It's not about being heavy or a hard core or hucking ... the rad is about bad design
What happens is the top plate of the heel piece gets peeled off because the shitty screws holding the top plate on break or because of inadequate support for the lifters the screws pullout
So the heel piece breaks during the skin up and then blows up when you are skiing, this a well known problemLee Lau - xxx-er is the laziest Asian canuck I know

^ I've also seen heel pins come out due to the top plate cracking. That's a fun one to discover on top of a 2K' couloir! Got my buddy down through a combination of voile strapping and duct taping his boot to his ski ...

I think the top plate cracking was about bad metal in the early days of the product, there was also the pin in the base issue which would crack the housing , there is also a problem with shitty screws that break more easily, I posted picts in a thread somwhere which show the differenves but i can't find em without my LT, I can just barely run this phone i can't really find on this phone, I am posting from a breakfast buffet at Annupurni

Well, seems like it's a well known problem and I'm out of the loop. Thanks for the info. So what's the best heel that dynafit currently makes (besides the beast). As in - which would you bring as a back up for a week long hut trip?

The. Verticals were the most trouble free tech binding but they don't make anymore, maybe you can find a lightly used setup?
If you take the forces of the boot on a climbing riser the older style is like a triangle supporting your boot while the rad is like a triangle with no hypotenuse it doesn't take a rocket scientist to see that something is fuckd
I'm on verticals over here and I got a spare in my duffelLee Lau - xxx-er is the laziest Asian canuck I know

^ They don't currently make a "best heel" anymore! The Speed Classic heels looked most bombproof.
The Speed Turn (1 or 2.0) looks like the same weak plastic barrel of the Speed Radical heelpiece but with a new metal non-hinged top plate. To be fair, most Radical heelpiece failures were of the lifter and top plate, and not actual barrel - but I've seen and heard of enough barrel failures to be critical of the design.
The Radical 2.0 heelpiece looks much beefier and improved from the Radical 1.0 heelpiece (thicker and reinforced barrel, strong ribs on top plate), but it's a first generation product and there are minor complaints about the brake lockout.:

Z, if you're not looking for a tech binding solution with elasticity, then maybe you should look into the G3 Ion.

the 2.0 top plate clips onto the housing and the screws now just locate the plate instead of taking all the strain of the flippy lifters.
The Flippy lifters are the BIG design fuckup, I suppose there could be other issues with 2.0 but dyna has at least fixed that issue
And there are older models still available that don't use flippy lifters but then you don't get brakes which I am assuming the op wantsLee Lau - xxx-er is the laziest Asian canuck I know

You had parts to zap together?
When mine exploded everything was lost in > half a meter of super light pow and i ended up spooning a tree so we had to strap the boot to the skiLee Lau - xxx-er is the laziest Asian canuck I know

Hah!
Here is my buddy's that I fixed with the same "tools" as you
Note that the lifter didn't fail, but he clipped his binding with his other ski and the plastic housing of the heelpiece just completely exploded.
It took us 5 minutes but we found all the springs, also within about half a meter, thankfully we were on a ridgeline of wind affected chalky snow so we didn't have to sift through powder to find this stuff._______________________________________________

When mine blew it was the two forward top plate screws snapping. I ski strapped the boot to the ski and called it good, then skied two more runs. I run rad toes and vert heels now. Only bust heel posts now, but that's undoubtedly due to ski flex.

Good half dozen years of 100+/- days on my verts, 15 years or so of less use (lately) on the tlt tourlite techs and no failures, just simple overuse wear and tear for the old schoolers well past their best before date. Tourlite techs heel pieces have ovalized plastic in the housings that mates to the spindle/shaft so they rock back and forth but still hold my boots onto skis. Good enough for me for for now on non life or death fall you die terrain and I ain't a hucker. Continuously variable binding ramp angle. Probably gonna experiment with some j.b. weld or something to fill the gap and ream it out with a round file manually if I get the time to see if that brings 'er back into spec and who knows if it'll last. Time/fatigue/moisture corrosion cracked alu base of the shafts/spindles so i j.b. welded the broken pieces and filled the fore/aft vacancies with ptex to keep it all tight in the fore/aft adjustment cavity. Seems to work.
