Product Description

From Black Diamond:
"Our inbounds ripper, the O2 binding transmits power from big boots to big skis — it’s the benchmark of precision for today’s aggressive skiers. Underfoot cable routing and powerful compression-spring cartridges keep the ball of your foot firmly on the ski, and as the heel rises, a progressively stiffer flex delivers power. The rear yoke features a rigid wire heelpiece, providing lateral stability and torsional support. Our durable one-piece stainless steel toe box with a variable height toe riser withstands the abuse of hard and fast freeheel skiing. The stiffness of the O2 can be adjusted with the three different compression-spring cartridges to suit your boot flex or skiing style preference."


Skiing Magazine '06:
"Unchanged since last season, the O2 maintains its status as a capable, no-frills binding. With three degrees of stiffness, it accommodates powder floaters, hardpack lowriders, and mini-cliff huckers. That said, the underboot position of cable and cartridges compromise torsional rigidity on harder conditions, even with the stiffest cartridge."

Backcountry Magazine:
". . . this compression-spring binding utilizes under-the-foot cable routing to improve binding clearance and increase power generation. . . .For today's wider boards, this binding offers serious power. Three types of spring cartridges allow 02 skiers to find just the right flex for their ski and boot type."

Coulior Magazine:
"If at first you don't succeed, try, try again..The 02 is the more active of the two bindings, feeling much like a Hammerhead in position 3.5. The 03 felt like a slightly more powerful Targa. The 02 is for aggressive in-bounds skiing, while the 03's more neutral feel make it a better choice for earning your turns. Their design borrows from the best ideas out there, but the real world has a way of delivering curve balls.I'd give these bindings another season of abuse by others."

Beefy binding
I bought these two years ago for my Black Diamond Havocs, which are a much bigger/aggressive ski than what I was on previously. So I figured I'd benefit from using a strong, stiff binding. After mounting these on the Havocs, and taking them out for the first time, I was really impressed with the linear feel of the O2. I personally like having the cartridges under my boot, and out of the way from clanking into each other while I'm transitioning out of a turn and into another. This binding is simple and efficient, and I can't imagine any particular part being prone to breaking in the near future. The only thing to watch on these is the fact that the cartridges have a tendency to loosen on the their own during the course of a ski day. As long as you're diligent about checking/re-tightening the cartridges before before clipping in, you shouldn't have an issue with the BD O2 binding. Now, I just need to get a better boot to match my Havocs and O2's...
