Now you can get your I-on without brakes. After a successful, virtually problem-free, introduction of the ION in 2014/15, G3 is now offering a cornucopia of I-options. The LT 12 version is basically the same impressive platform as the original, just without brakes. Wide toe jaws with snow-clearance channels, bi-directional heel rotation, and release values that range up to 12 still apply to this version. As does the much-acclaimed ease-of-entry, due to the simple boot-stop guide. Basically you get all the I-awesomeness but with free leashes instead of brakes, saving you weight and cash.
- Fully featured with two risers, a flat mode, and a toe lever that can be locked or unlocked.
- Heel pieces are spring loaded, helping to keep a consistent release throughout ski flex.
- Toe wings are raised up to create deep snow-clearing channels that prevent icing.
- Simple Boot Stops shorten the step-in learning curve for previously fiddly tech-bindings.
- QuickFlick risers (x2) can be flipped in either direction, regardless of how you turn the heel.
- Wide-angled toe wings can hold your boot with more force, avoiding some pre-release.
- Mounting pattern is 30% wider than competitor models, for better hold and power transfer.
- Heel can be adjusted within a BSL range of 22mm so you can use multiple boots.
- The raised toe wings and a streamlined heel keep you flatter on the ski vs comparables.
- All adjustment mechanisms and mounting screws are Pozidriv #3 to keep things simple.
- Optional crampon system slides under the toe piece and is easy to affix and operate.
- Leash connectors can be mounted under either side so you can point them both outward.
- Manual comes with pro-tips such as how to enter ski mode levering your pole off your boot.
- Leashes included (+17g).

Questions & Reviews
I've used them for 5 years across 3 pairs of skis with minimal issues and maximum customer support from G3 / G3 dealers. They keep my toes locked tight, release when they're supposed to, are confidence inspiring and incredibly easy to use, have the best ski crampons ever, and have served double duty as an inbounds binding for two seasons. The only issue I've had is that the rubber which holds the heel pin in place has broken, but this is easy to fix/replace - see pic for disassembled heel turret. Highly recommended.
Boots used with the Ion LT12: Dynafit Vulcan
Skis used with the Ion LT12:
- Moment Underworlds
- Blizzard Zero G 95s (would recommend a lighter binding)
- G3 Synapse 109
It was worth a shot, but you're correct that it won't work. You'll be drilling new holes if you switch bindings from the Radical 2.0 to the Ion.
From your pin height table, it looks like the boots on these sit 1-1.5cm higher than a lot of other bindings - both toe and heel, I am not referring to the delta here. Theory says that this should make it easier to edge the ski, but that it might also be less stable (think of riding on stilts as the extreme). Is this difference small enough not to be noticeable in real life?
Some more of those refinements include a beefy heel riser, space for a pole tip under the toe wings and sweet wedge-shaped block under the heel in flat mode, which facilitates snow clearing beautifully.
This is my burly everyday binding for everything from slackcountry laps, to fast turns on alpine faces, to ill-advised pillow lines and shady doubles on Rogers Pass ski outs. I do reach for something lighter on the biggest days, but that's not a knock on the Ion in my book. It's designed to feel solid and ski well at a reasonable weight, and it delivers.
