Ski Trab Toe Pieces

Forrest- The best way to mount these on a splitboard is using the Plum Low Tech Adaptor plates (or similar Spark R&D plates). This toe has the old Dynafit vertical hole pattern (minus the 5th hole).

This information is in conflict with the lower comments, the chart provided by this website as well as my personal experience. I will attach a picture of my old speed radicals (which I bought with the R&D adapter) and my trab vario toes. Speed radicals read 1 1/2" fore aft, trab reads 1 1/8. Very similar edge to edge. NOT the same! It is very hard enough to create a new franken binding almost every season without being fed misinformation about new products.

Forrest- You are correct the Dynafit Radical and the Trab have different hole patterns. The older vertical toes and Trabs do have the same hole pattern minus the 5th front hole. If you look here you will see the Dynafit Verticals and Trabs are .5mm different which will work fine with an adapter plate.

The spark RD toe adapters were made for the speed radicals. I bought these packaged together as soon as they came out. The bindings I sent a picture of were sent as a package with the spark rd adapter plate and were first used on a split. I abandon this design for several reasons but I do still have the plate. My plate has 5 holes for which I used 4(no center screw in my speed radicals). After looking at the RD site I see their newer adapters have 7 with a set at 26.5 as you say, mine do not have those... Sorry for not believing you but I was holding a part in my hand that proved different. I apologize.
Being a hardbooter can be super frustrating as I look at the hundreds of options skiers have and I can't find a single working option for splits. On my skis I have the Trab vario 2 and it's worlds away from thengear offered to splitboarders. We are left in the dark ages. This Puts me out there in major situations with makeshift gear. Not a nice feeling.
Still on the RD site it states the R&D adapter plate is designed for the use of Speed Radical, Speed Turn, or Low Tech Race toe pieces. It seems I would need to purchase a new adapter plate (which adds cost, weight, complexity and offsets the toe hinge point forward). However this may be worth it in order use the trab toes, which are the best ski toe design out there but still overbuilt, expensive and with too large a footprint to be a good option on a split. I've already run through too many ski toes and adapters. The original voile pin system is lighter, smaller, cheaper, simpler and easier to repair in the field than any ski toe adaptation so far. But it's clunky and leaves the weight of the slider plates on your feet while touring. The ups and downs of a hardbooter.
While people assume splitboarders don't need an efficient set up for some reason, but let me reiterate that we are out there doing the same stuff you are. I will be out on multiple 20+ day self supported ski tours this winter. Right now I would not attempt this on my split because the equipment just isn't there yet. But I'm tiring. I see you are too, I thank you for that. Let's keep it moving forward and not support plum or dynafit/phantom who are putting out subpar gear and see if we can't get trab to make an actual splitboard binding.

Hi Nick,
Ski Trab toes do not have the same mounting pattern as Dynafit Radical toes. We have a comprehensive list of all of the different mounting patterns here. However, the Kreuzspitze Telemark Kit will mount with the Ski Trab toes just fine!

Thanks Julieana, that’s good to know.

It is the same as always.

Hi Chris, we just updated the specs for 2018/19. These weigh 66 grams with the striker plates (no crampon, etc).

Hi A-fro! They're sold individually.

Hi Paul, I can't speak specifically to the Spark crampons, but yes, the Trab receptor fits Dynafit-style slide-in crampons. The worst-case scenario is you'd need to bend it outward slightly if the bar is on the thick side.
