Mount Pattern of Different Dynas...?

[margotron]

I have Radical 2.0s. I have searched far and wide but can't turn up what other dynas will go in the same holes or if I need to drill again to fit lighter dynas, say, speed radicals.

Did I miss a resource somehow?

I will say just having mounted some rad 2.0s that neither of the two paper templates in the MYOFS thread work

So I’m guessing there isn’t much overlap

Rad 2.0 definitely has a different mounting pattern than OG speed rads/turns etc. Here's a good resource for spec comparison:

I believe Radical 2.0 and Rotation are the same, the rest are a smaller footprint.

Radical 2.0 and Rotation are the same. Radical 2.0 shares the same toe with the Beast 14, but the heel is different.

Speed Radical is the same as Radical 1.0 and Vertical and Comfort although comfort (and Vertical?) have fifth mounting toe hole in front of the four.

Not quite. I'm 99% sure that the spacing is different between Speed Rads/Rad 1/Speed Turn 2.0 and the Verticals and comfort. It's not just an extra hole. But I'm too lazy to walk out to the garage to verify.

You are correct. Pic below courtesy of 1000-oaks. The good news: It's easy to upgrade from 5-hole Dynafit toe to Speed/Turn/Rad 1 4-screw toe because the rearward 2 screws are in the same position (relative to pins).

Oh man... That's right. Good catch. I had forgotten that they made that move forward with the toe holes on the Radical 1.0s. I have, in fact, done the remount (adding the two additional holes) that Steve alluded to when moving from the verticals to the radicals.

As Steve points out going from 4 hole to 5 holes is easy because you reuse the 2 rear holes but it also means you put 3 holes straight across IF you use the 5th hole

I was remounting a pair of Denali and I didn't wana risk 3 holes across on a superlight ski so after asking around on TechTalk the consensus was you don't really need to use the 5th hole and I did not find any down side to not using that screw

This is confusing. I mentioned upgrading from old 5-screw to newer 4-screw, not the other way (a downgrade), although it wouldn't be a problem. Also, you never end up with 3 "straight across" holes. See 1000-oaks pic. There's ample (>15mm) distance between screw hole centers even if ski is drilled for both old 5-screw and 4-screw Speed/Turn/Rad 1.

yeah I was going from RAD1 to verts, I bought the denali half used off a bro, he had rad1's, he had broken a ski in ONE run on soft snow running into a ditch or SFT, dynafit sent him one replacement Denali, this was back in the beginnings of the super light craze, I had some new verts sitting around, buddy thru in the skins, I lowballed an offer and I was into a superlight ski for way cheap

So I use the 2 rear holes for either binding but then one-run ski has the 2 holes up front for RAD1 that I plug with wood & epoxy but if I use the middle screw of a 5 hole vert I would have 3 screws almost straight across enough to worry about breaking a superlight ski, keep in mind the other ski of the pair has already broken,

so I didnt use the 5th screw and IME you don't need to

in view of all the peeled off top plates, going from RAD1 to Verts is an upgrade ... IMO
