Black Diamond O2 Ski Binding -

The Black Diamond O2 Ski Bindings. Our inbounds ripper, the O2 binding transmits power from big boots to big skis-it's the precision choice for today's aggressive skiers.

FEATURES of the Black Diamond O2 Ski Binding.


  • Standard size fits boot sole lengths over 315 mm


  • Underfoot cable routing
  • Three cartridge options for customizing stiffness each includes a color-coded tension indicator
  • One-piece stainless steel toe piece
  • Solid wire yoke heelpiece
The Black Diamond 02 Telemark Bindings provide the power and control that hard-charging tele skiers need to push the limits. Under-foot compression springs create a progressive flex that makes the O2 Telemark Bindings a great choice for driving big sticks. Black Diamond designed them with a solid heel wire to increase torsional stability for snappy edge-to-edge transitions. The O2 Bindings have what it takes to launch a massive cornice or power some fatty planks in funky, beat up snow.

The Black Diamond O2 Telemark Binding is one of the strongest and highest performance telemark binding built today. A unique yoke and solid wire heel piece add lateral stability and torsional support for an added edge in rough conditions. Under-foot cable routing keeps the ball of your foot on the ski and provides progressively stiffer flex and power when it's time to put the hammer down while the variable height design of the metal reinforced toe riser matches the angle of the boot sole to reduce tip dive. Adjust your flex with compression-spring cartridges, available in three stiffness ratings - FreeFlex, MidStiff and Ridiculously Stiff.

Positive Reviews:

I'll start by saying that I really do dig these bindings- they've taken me many cool places, and performed in some sticky situations. I have two pairs of these that I've been on for the past 4-5 years, in both Big Mountain and Park skiing. I've had to pick up the small cartridges for both (if you do this, make sure they give you the smaller housing as well, or else they'll still be loose if you have a small boot). But yes- they tend to loosen themselves when you ski, so you are constantly having to tighten them up. They recently came out with newer cartridges that supposedly helped fix this issue- I haven't tried any of the recent models, so I can't say for sure. They also recommend throwing on a piece of tape to decrease the chance of them loosening up when skiing.
Overall, even though it's a bit of a pain having to make sure that your bindings are tightened up at the beginning of each day, I still love the 02s. They're great for charging, throwing down in the park, and just having a good time!

I've read a lot of the posts slamming this binding, and feel they are unfair. I have owned several pairs of HH's, and while they do ski fine, I really did not like the loose tolerances and broken heelpieces. I always felt that the duckbills were sloppy in the HH, not so in the BD02. Frankly, I think the pivot point feels better in the 02 than the HH, the engagement of the springs smoother. Once the binding is installed and the cables seated, all that is needed is a narrow ribbon of Gorrilla duct tape to "lock" the cartridges together, and they will not loosen! True, the HH has fewer moving parts, but I don't feel it skis tighter or better than the BD02 when correctly set up. It should be noted that BD has not changed the design of the 02 for some time, and HH's are ending production.

I have had two pairs, and they have performed well. The old style need to have lock tite on the threads so the round nuts at the front of the barrels do not come loose, The newer style do have to be tightened occasionally. I have been skiing at Taos for over 300 days with the combination of the two bindings on pretty big skiis. Mostly bumps, powder, and steep shutes,ie; (in area).
I have not had a failure of the bindings and really like the way they pull from under the sole of your boot rather than the side.
I could see increased stress on the heel piece if you tend to bend your rear boot to 90 degrees.
All-in-all, they have worked really well.

I have been on these bindings for three years now and love them. I like the pivot point on these bindings way better than the Hammerheads. I currently have the rid-stiff springs on a pair of 188 LIB TECH Freerides and it is a great in-bounds setup. I don't use these ski's or bindings for my hiking setup. I have a lot of preload on the springs and haven't had a problem with springs coming loose. I know if you don't have the BD compression spring cartridges tight they do tend to give you problems...but then so would my pair of Rottefella Hot Chilis back in the day.

I used to hijack my dad's old Rivas until I got sick of too little tension and a few too many nosedives. Picked up a pair of O2s and while they took a little breaking in and are definitely heavier they get the job done. They flex evenly with my garmont boots and I've never had any problems. The weight doesn't bother me either and I have no problem touring. I see guys on the O1s but I'd rather have a little tougher climb with fewer mechanical problems if you know what I mean

Mounted in 2 pairs of skis (BD Havoc and Volkl Karma). Rid Stiff cartridges were awesome! I ski very agressively and they never pulled out of skis and had great feel. They do need constant adjusting and tend to freeze such that you can't adjust and have to bring inside to thaw to adjust again.. but that was never critical, just an annoyance. The duct tape trick sounds like it should be effective.I'd recomend, but not for touring.. just on lift served. Get the 01 for touring.. just as great but have touring mode

My other O2 are mid Stiff but those Ridicul. Stiff are the one I needed with a hard ski and need power to deliver what we are expecting from them. Go aggressive and you'll like them.

Negative Reviews:

Um, I'm sorry but who wrote the product description for these? I'm guessing Black Diamond because it couldn't be more wrong. "The O2 Bindings have what it takes to launch a massive cornice or power some fatty planks in funky, beat up snow." These bindings can't even handle my Karhu Team 100's (100mm underfoot). I have the rid stiff cartridges on them and they are still far from being "tight" or responsive. Very loose and sloppy when skiing pow, steep lines, and choppy conditions. On top of that, they "squeak" on every turn,(a sound that I am pretty sure comes from the boot sole rubbing on the plate, and definitely not from the cartridges, which are brand new). There's a reason pro tele guys, like the boys from Powderwhores, are riding Hammerheads, Axles, or NTN setups. Sorry for the harsh review BD but you should be sued for false advertising. Your bindings suck

I bought these and mounted them on my K2's with the intention of having a great all mountain set up. These bindings were a waste of money. They are constantly loosening up and I have to crank them down every time I ski. They were supposed to be the mid-stiff but not as nearly as much as advertised. For the cherry on the sundae I was skiing at Keystone and my binding loosened up again allowing my boot to pop out and off my ski goes, on a adventure never to be seem from again. Try Hammerheads or G3's much better deal.

Katkool at on 01/31/2011

I've ridden this binding for the past year and a half and initially liked it a lot. As time has gone on I would not recommend this binding since there are better options out there. I think it performs ok but you have to constantly re-screw the cartridges which leads to inconsistent performance. At times I've had to change this mid run because it loosened so much and locktite and thread tapes never helped long. Kind of frustrating when every other binding I've used is a set it and forget it deal.

Garrett at on 01/08/2012

I have had the bindings rip out twice. The first time it happended I thought install error and had another dealer remount them onty to have them tear out again. I recently have been discussing this with different shops and pin heads I meet and am finding that it happens very often. I would be interested in knowing if other people have had this issue.

Neutral Reviews:

Nothing standout about the O2 for me. It gets the job done. I have a pair of O1's and they seem to have a slightly different pivot point. Even after adding plumbers tape to the threads and properly preloading, my cartridges just spin loose all the time. The binding feels sloppy on hardpack. It's a fine binding and all, but there are better choices for your standard telemark binding. A lot of it is preference. I have friends that love the O2, but I am not crazy about mine. The BD warranty is pretty good though. Cracked a heel throw and they just gave me a new free one.

Kate Atha at on 12/13/2010

The O2 is a decent binding for the resort but there are better options such as twenty two designs. The need to constantly re tighten the cartridges constantly is a little annoying. I recently sold mine because of the lack of touring capability. On the good side these bindings are very smooth.

Vince R. at on 11/20/2011

These were the first pair of tele bindings I ever used. They were adequate for the job. Most people will be perfectly happy with them, yes they have a couple of flaws, a little duct tape, or locktite fixes that.
