Dynafit Mod — Easy Switch Between Tour and Alpine Mode

This modification adds a small homebrew device to a Dynafit backcountry skiing binding for easy switching between tour and downhill mode without taking your skis off. Unlike other methods of switching, it requires no contortion or gymnastics, and won’t break the red post off the binding. We’re in the process of figuring out how well it works with ski brakes installed, will report back on that soon. Caution, this is more an experimental mod than anything we suggest spending time on.

Dynafit Backcountry Skiing Binding ejection mod.

This mod is made with a 1 1/4 inch paint scraper blade, a chunk of angle iron, a small section of steel tube, and a length of 5/8 inch aluminum plywood trim “C” channel. I got the idea from backcountry skiing publisher Brian Litz, who told me over the phone he’d seen a guy who’d made something that you “push down with a ski pole to change modes with a Dynafit.” It wasn’t tough to figure out what such a thing would be. A bit of trial and error, and here it is (this is an experimental version — we’ll build a cleaner one with nicer finish when we have time, as it works quite well). I riveted all the essential parts together, and welded the small chunk of tube used for the “pole tip socket.”
