Thanks guys.

I liked the cable management on the SP binders better than flows, seems like they should feel a little more like a traditional high back. I’m pretty stoked to do some long flat approaches and split skiing on these with the straps around the top.

They feel a bit softer now than with the stock highbacks, partly due to some give in the cable, hopefully they hold up. I’m going to carry some cord to patch them up if I snap a cable.

Potentially.

These are built on a magneto baseplate upgrade kit, straps from my old burner bindings, and the gnu highbacks. I wouldn’t want to use the straps from the gnu bindings, since the toe strap doesn’t have a ratchet and the heel strap is built to pop open when the highback moves.

Nice work Dude! I’ll be looking for some old flows at this years ski swap. Any reason this wouldn’t work on a Fuse baseplate?

Nope, no reason it wouldn’t work, just adjust the aluminum plates to fit the heel cup mount hole pattern. I was originally looking to adapt this to my Ignition IIs a few seasons ago, should be possible on all spark bindings.

I am looking at making a second iteration of my adapter plates. I want the cable to pull on the plate exactly in line with the forward mounting hole, so that there is a more direct load path. I think some of the extra rearward flexibility I am experiencing is due to the plates flexing outward when the cable pulls on them.

Anybody have a slick way of shortening flow/fastec type cables? Or making your own?

I do not have access to a 3d printer. Any ideas on how to figure out a template?

Thanks

Trace your current heel cups bolt pattern on to some Al plate, then before you disassemble the donor binders, measure the vertical position of the flow/fastec highback in relation to the footbed. Drill the highback mounting hole at that height, and at the approximate horizontal position you desire. If you drill several holes to mount it to the spark baseplate, you can adjust the horizontal position for the right fit. Al is pretty cheap, so don’t worry if you mess up the first set.

Hi Frank,
Can you post a picture of the finished adaptor plate by itself? It’s a little difficult to get a feel for the forward cable attachment with the black on black.

Ill try and grab a pic one of the plastic prototypes tonight. I basically just copied the way it mounts on the Gnu binders. There are two holes, one for the screw and another accepts a plastic protrusion on the end piece to keep it from rotating. This is sort of shown in the first pic of the thread. In that pic, I was experimenting with mounting them to the inside, but I settled on the outside for boot clearance reasons.

Getting the placement of the cable holes relative to the highback mounting hole is pretty crucial, however, you can adjust the forward lean to compensate if it is to close or far away.

FYI I used 1/8″ AL plate, but it definitely flexes a little when the highback is loaded. I would recommend trying to place the cable mount in line with the bolts to the baseplate for a more direct load path. This wasn’t possible for me based on my fore/aft positioning to fit the boots. It could be done by shortening the cable.

The SP bindings do have the reclining high back, but they are just a standard binding, welded to the voile plate. Not really cutting edge.

The new PLUM bindings had them in some images I saw.
