G3 Genuine Guide Gear Onyx Brake Set -

The G3 Onyx Brake Set is made specifically for the Onyx binding. The ONYX Brake has a reliable deployment system ready to stop potential runaway skis. The unique design of the ONYX Brake allows for the brake to remain deployed during step-in for both ski and tour mode, ensuring that the ski remains stationary during this process. Easy installation and zero interference with the binding's overall usability, elevate the ONYX Brake to meet G3's highest standards.

If you’re a guide in the backcountry, other people’s lives can depend on the gear that you choose. That’s why, in 1995, when G3 started making avalanche probes, they decided to hold every item they made to a higher standard. Will this piece of equipment improve the abilities and safety of professionals who live and work in the backcountry? The design of the ONYX binding is focused on the best combination of lightweight, high performance, and usability. We stayed true to our commitment to lightweight by designing an enhanced Tech system toe attachment that provides a rigid and secure boot interface, an easy step-in experience, and a high level of retention. We then added a heel mechanism that shifts fore and aft to allow for an easy switch between ski and tour mode without having to release the boot from the binding. Finally, we added an easy to adjust mounting plate system so that one mount fits multiple boot sizes.

Seem to struggle sometimes to get in to your G3 Onyx bindings when the snow is variable. Put on the proper pair of brakes and take the hassle out of getting in and out when conditions are dicey. Bonus these breaks pop-up when in touring mode so they stay out of the way(which is a really cool feature for these).
After a tough bootpack up the couloir you prepare to ski down. Unfortunately, one of your skis wasn’t quite as anchored into the snow as you had thought and decided to leave without you. Next time count on the solid and easy-to-install Onyx Brake Set to help stop your runaway ski.

G3 Genuine Guide Gear Onyx Brake Set Reviews:


All 3 were shipped as 110 mm bindings that would work skis with up to or equal a 110 mm waist.
All 3 pairs measure inside the spread of the forks a 95mm.
None would have fallen past the ski on my 104mm ski.
Finally asked for a 130mm set, but have yet to receive.them.

I have received 3 pair of G3 Brakes, noo-were the size labeled on the package.
I finally requested a pair of 130mm to put on my 106mm waist skis. The 130 mm measured 110mm between the forks.
Some quality control needs applied.

Got the 130s for my Voile drifters and while they clear just fine, they seem very sticky and don't deploy reliably. Don't really like the whole Onyx binding system. Next time I'm back to Dynafits.

They stop skis and more importantly let you ski in resorts. Not perfect and unreliable off groomed terrain, but there you dont need a brake. Easy to take on and off the onyx though.

After only a few days on these, the brakes stuck and didn't work.
