Maruelli is the Italian version of B&D, making useful aftermarket parts for tech bindings. They use the highest quality materials to ensure modified products are even more robust than they started. Find our growing list of Maruelli binding parts below.

Speed Antitwist Base x2 – Machined out of Titanal, this bomber heel baseplate/spindle for the Speed Radical binding has a metal post that prevents unwanted rotation while skinning. It mounts directly onto your ski, lowering the heel pins by 3.5mm for a flatter ramp angle. There is 6mm of fore/aft adjustment if you mount it with inserts. 37 grams (1.2 ounces) each, lighter than stock heel bases.

23 mm Base Tracks – Adjustment tracks that provide 23mm of fore/aft range for the Speed Antitwist. The tracks use the standard Dynafit heel pattern so they can be used as a drop in replacement for an existing heel tower. Made with the same aerospace-grade aluminum alloy as the bases, the tracks are 7.5mm thick and weigh 34g per ski with the included Inox (stainless) adjustment bolts. Two pairs per pack.

73 mm Base Tracks - Maximum adjustability for you Antitwist heels, with a total travel distance of roughly 73mm. Mounting pattern is the same as Dynafit rental bindings so a standard jig works. The tracks are 7.5mm thick and weigh 47g per ski with top-of-the-line stainless steel (Inox) adjustment bolts, included with the two pairs of tracks.

Radical Antitwist Locks - Metal brackets that slide into Radical ST or FT heel pieces to prevent unwanted rotation while in touring mode. Remove any legacy pins in the heel tower and screw on this final answer. Sold in pairs and come with Inox bolts. 27g per ski including hardware.

Click-Clack Risers - Flipper-style risers for the TLT Classic and Speed Turn bindings for those who prefer pole tricks instead of wrist kinks. Also decent replacements for broken Radical roofs.

Leash Safe Loops x5 - Breakaway leash loops to ensure you skis don’t pull you down in an avalanche. Connect these somewhere along your leash chain and they will break when the right force is applied. 6 grams per loop, sold in packs of 5. Note these are the newest version that only require 1 loop per ski (previously they needed to be doubled up). Breaking force is around 75lbs.

Installation instructions and mounting templates for the Antitwist parts can be found here. You can read more about the Antitwist solutions on WildSnow.

Question from Jon
 
I'm re-mounting my Speed Radicals & Maruelli's base only onto a new set of skis. This time I want to use "Quiver Killers". I'm not sure if the "Quiver Killers" fasteners screws (pozi-lowhead) for the heal piece will work with my Marueli bases. It appears that Pozi-flathead M5 screws is what I need to use to screw down the Marueli bases into the inserts. Is this correct? It's hard to tell from the images. Also what length pozi screw would I use?
I appreciate you help, much thanks . . .

Answer from jbo
 
Hi Jon, the drive type isn't critical, but you want 12mm M5 flatheads for that application. We have fastener kits in our QK listing.

Question from Gary S
 
Does the antiwist base come with mounting screws? If not what length screws are needed? Thanks

Answer from jbo
 
Hi Gary, they don't come with screws. If you are mounting with the Base Tracks, you can use the screws from your Speed Radical heels, or get more pan head Torx screws. You'll need 12.5mm Torx screws for a mount without the Tracks. Screws are here.

Question from Austin
 
Hey Skimo Co,
Would the Maruelli Antitwist possibly work with an older Vertical FT heel unit, if the anti twist post was filed down? Would it turn in either direction like the old Vertical bindings.

Thanks
12/8/2014
Answer from jbo
 
Hi Austin, it wouldn't turn in each direction since there is a post to prevent rotation while in climbing position on the Radicals. However that position on the Verticals is flat-on-ski, so in effect you would have no risers unless you also added the Click-Clack system from Maruelli.

Hey Skimo Co,

Would the Maruelli Antitwist possibly work with the Speed Turn heel unit?

Thanks

Answer from jbo
 
Hey Tyler, yes, the Speed Turn heel housing fits on the Speed Antitwist Base. However there are only two heel positions with this base: skiing & 90° clockwise. That second position is climbing mode on the Radical, but flat mode on the Turn. To be useful, you'd also need to install Maruelli's Click-Clack system to give climbing aid.

Question from David
 
Wondering if the Maruelli antitwist base plates can be used to convert a Radical ST to a kind of a Speed radical i.e. sans brake and plastic base plates etc.
11/3/2014
Answer from jbo
 
Yes David, this can be done but requires some modification. The plastic protrusion near the base of the ST/FT that holds the brakes up in touring mode will hit the anti-twist post. It needs to be cut off (better) or filed down (often good enough). There is a picture of a filed orange FT here.
