Fun was had this weekend. Fasteners were twisted. Gleaming IONs were locked to shiny Fischer Hannibals. ION observation: They have strong springs, watch your fingers. Hannibal observation: The super-strong binding mount plate does exist. Drill with the 4.1 mm ski bit and tap for sure. I had some trouble of my own doing, got lazy with the hole sizes and found myself twisting too hard on the screws. You have been warned.
I know the guys at G3 sweated blood over ION, so we could all enjoy it. I embedded their video in deference to their hard work. Yeah, this is the first season for production ION so let’s not rush the concert stage quite yet, but it’s looking good. I’d suggest giving it a go if you want to try something new.
If you’ve read this far, here is a bonus tip for mounting ION. The heel unit base doesn’t have any provision for your screw holes in the ski to “volcano.” If that happens it’ll jack the binding up off the ski and you’ll be trying — futilely — to tighten the screws and get the binding tight to the topskin. I’d advise a slight countersink of the mount holes, to prevent volcanoes from developing.
