Dynafit Beast 16 Heel Internals and Tecnica Cochise Boot — Part 7

Post by WildSnow.com blogger | September 6, 2013      

Tearing down the Beast 16 heel unit is a kick. What’s satisfying is when you reassemble the aluminum heel post spindle locks into place with a pleasant tension that’s almost, should I say it, intimate?

Tearing down Beast 16 is an experience in mechanical intimacy. Consumer testing will tell the tale, but possibly an engineering masterpiece.

See the intimate details in our Dynafit Beast 16 FAQ.

Oh, and someone asked about installing Beast heel fitting on Tecnica Cochise. I just so happen to have a pair of Cochise here in the mod shop, so I dug in. Check the photos.

Cochise prongs are slightly larger than those of Beast fitting. To prevent micro movement you would thus have to bed the Beast prongs in JB Weld mixed with a bit of steel wool. Screws in sides of Beast fitting protrude through heel block and would insert into main body of Cochise, which is good.

Side screws on Beast fitting will mate sole block with main boot shell.

    Seem to me that the side screws going through into the boot is not a good thing if you swap soles with any regularity. For a one time solution yes it would be stronger but eventually you run the risk of stripping the threads in the plastic.
    I wonder if you could get away with using shorter screws on the side or even a pem nut type insert that would allow swapping more easily.

    Abraham, I think you could probably use shorter screws, but a rivet with backing washer countersunk would probably be better. And insert could be good as well. I don’t know anyone who swaps soles with any regularity, but I suppose they exist somewhere on the planet (grin). Lou

    The Cochise heel blocks don’t need to be changed anyway-the tech heels work fine in alpine bindings. I think they are only one or two mm higher than the alpine heel blocks.

    I bet you’d want to swap your heel pieces out before stepping into alpine bindings once you got done installing that Best heel fitting on them.

    That said, most of the people I know with swappable soles don’t seem to swap them frequently. If it were an issue you could always install a threaded insert into the boot plastic. Might take some careful drilling but the original screw hole could provide a guide hole.

    S, indeed, it appears that swap soles are most often used as a one-time configuration option. I’m not surprised, as the last thing the busy person wants is yet another mandatory gear fiddle before they can hit the slopes. More, some of the swap soles have fasteners that thread into plastic, so they have limited use cycles.

    Good point about how the Bast fittings obviate use of alpine bindings, while regular tech fittings do not! That’s actually a pretty big deal for some folks.

    Thanks for the Cochise demo Lou.

    And thanks Tecnica!

    Could you get a alpine binding to work with boots retrofitted for the beast? If not, it seams that this assumes people will run only one binding — or go through the trouble of switching heel inserts (also assuming people hold to the Dynafit recommendation).

    Thanks Lou!

    Tom, you could probably “get it to work” but I’m not sure about the definition of “work.” Alpine boots are standardized in shape for interface with the binding, the Beast heel fitting makes a radical change to that shape and though you could probably snap into an alpine binding with the fitting on a boot, how it would behave in terms of release, friction, etc. would be an open book.

    Yes, I’d say the whole concept with this is you’d use one binding for everything.

    (Though we’re fairly certain that with the correct mods you could run the Beast heel fitting in any normal tech binding.)

    I’m a little late to the party, but I’ve just got my original beasts set up with Cochise Pro lights and the toe seems incompatible. When I do a kick turn with the toe locked out, the toe releases because the toe box of the boot makes contact with the release mechanism. Lou, did you find this in any of your testing ever? I never saw the Cochise on the list of incompatible boots 🙁

  11. Lou Dawson 2 March 12th, 2017 3:26 pm

    Hi Cam, what you describe has been going on for years with various tech binding and boot combos. I’m not suprised, though I didn’t personally experience the exact combo you describe in our evaluations. The situation has become rediculous, an embarassment to the industry that they (we?) couldn’t have come up with more concrete standards by now. But I suppose so long as they can keep selling stuff (and we keep blogging about it, smile) there is not much incentive for them to improve. Another example is the recent confusion on myself and other’s part about what boots are compatible with Fritschi Vipec.

    I’d add that now that the tech binidng world has become so hightly cuthroat, this situation could become even worse. Or, it could get better. I think we’re at a point where it could go either way.

    While I do have a lot of binding and boot samples, the problem on my end is I’m willing to test and report, but I simply don’t have time nor is my product inventory complete. I’ve got a lot of bindings, but don’t evaluate every boot out there The bindings sometimes don’t come into our possession until after they go to retail, or even more problematic, they get “inline” changes while keeping the same model name and SKU. The latter confuses the heck out of everyone and is a consumer nightmare when the inline changes are done to fix a defect or incompatibility. I still deal with this on a nearly weekly basis wtih the Radical 1.0 heel unit breakage issue. I even found myself checking through our test bindings the other day, trying to weed out ones that might be problematic. This with two brands and models, not just one.

    We’ll probably laugh about all this stuff someday, but but presently it involves very real issues with money and even personal safety. So it’s not funny.
