I am wanting to mount some speedfits to adjustment plates to accommodate my wife's minus 4 to 5 size hoofs. For toes, I have sourced a B&D radical compatible shift plate, but speedfit heels are not so rad, and I am having some trouble sourcing an adjustable speedfit heel plate. I believe 28mm is the speedfit heel hole width, which matches the LTR 2.0 width. This page description cites "old low tech race" but the hole pattern chart lists two LTR's. Which hole width does this LTR heel plate fit? https://skimo.co/tech-binding-hole-patterns
Hey Evan. Unfortunately, I think you're out of luck on the heel adjustment plate for that binding as it already sits on a small track that gives about 10mm of total adjustment range and the toe shift plate is probably your best bet. In theory mounting the heel on one of those adjustment plates could work because you are correct, the hole pattern of the heel is the same width as the LTR 2.0. The issue I'm seeing with mounting the heels onto any of those adjustment tracks is the length of the hole pattern would likely overshoot the entire length of the adjustment track or at least eat up an overwhelming majority of the length which wouldn't do a whole lot except for be an expensive way to add weight and raise your binding delta.
One of the first ever LTR bindings (before the times of SkimoCo) had a 4-hole pattern which the Kreuzspitze LTR Heel Adjuster is compatible with, but pretty much none of the existing bindings on the market will drop into that plate.
