You just need the cartridges, all the other parts are the same.

Thanks Alexander!!!!! The TJ is 299mm and you are right they are very soft!! thanks for the advice!

# Standard size fits boot sole lengths over 315 mm
# Small size fits boot sole lengths under 315 mm.
Not sure exactly how the TJ measures at a size 25, but you can just take a tape measure and do it yourself. Those boots will fit the O2s, but I'd get the free-flex cartridges, as the bellows on the TJs are very soft, and the O2 is capable of overpowering soft boots.

Yes they are compatible, and you should listen to Nick and get the O1s. He knows what he's talking about...

Write your answer here...I am pretty sure they do, but I would highly recommend the 01's.

Not quite sure what you mean by "catching on your boot"... As for the cartridges bottoming out, O1 and O2 cartridges reach their spring limit because over over-tightening. You might have them cranked down too tight. When BD says that only 5-10mms of metal should be showing outside of the cartridge, they mean it. In my experience, aggressive knee-droppers barely want any metal to be showing when clipping them on. With your foot size, the smaller cartridges should be right for you, so try loosening them up. If you feel like the resistance isn't enough, buy the Rid-Stiffs, and if that isn't enough for you, you should get a pair of Hammerheads.

If you're willing to spend a little more, the O1 is the binding for you. Even if you don't tour that much, having free pivot at your fingertips (or your pole-tips) is incredibly convenient. The instant you start on the uphill you'll know why it was worth the money.

First of all, don't buy the O2s, they are neither powerful, nor good for touring. I agree with Bud, I have both HHs and O1s and the HHs kill it on the downhill. If you're touring all the time, O1s are a great choice, but for aggressive resort tele skiing the Hammerheads are the one you want...

I have both the Hammerheads and the O1's with rid stiffs. The Hammerheads absolutely kill the O1's. Plus the Hammerheads will tour better than the O2's if you move the pins. Definitely go for the Hammerheads.

Hey Gary, do remember that if you are using stiffer cartridges and stiffer boots with these (like t-races or customs), to epoxy the screw holes. The four-screw pattern plus the underfoot cable system puts a tremendous amount of torque on the back two screws which can rip them out of your skis. My O1s (which have the same screw pattern) ripped the inserts OUT of my K2 Anti-Pistes, so make sure to tell the shop to epoxy the crap out of the insert holes...

thanks Angus, Gary

These fit the K2 inserts perfectly, I've skied Hippy Stinx, Piste Pipes, Super Stinx, World Pistes, and Work Stinx all with O2s and they've all been bomber.

If it's the Piste Pipe with the inserts, then you want to mount the front of the toe piece in the forward-most holes on the ski. Then mount the heel piece wherever your boot needs it. If the Piste Pipes don't have inserts, you'll have to get them mid-mounted in the shop.

That has always been a problem with these bindings, though changing it would sacrifice durability and simplicity of design. I've found that I can usually warm them up with my hands enough to unstick them, or if it's too cold for that, then flexing up and down a lot (at the risk of looking like an idiot) usually loosens them up.-----My old targas used to do the same thing, I would carry a handwarmer with me and unfreeze the cartridges with it...

You just need longer cartridges. Here you go.http://www.backcountry.com/store/BLD0934/Black-Diamond-O1-O2-O3-Cartridges.htmlDon't get anything with S in the name (e.g. MidStiff S). To swap them out, use a screwdriver to pry the small metal piece that holds the cables together away from the toe piece of the binding. Then the whole heel throw, cartridges, and cables will pull out together. Then you just unscrew the cartridges and replace them. Don't even need tools. It's a 30-minute job. Good luck.

Nope, that won't work. Too small. Chances are if your feet are small enough for small cartridges, you're light enough not to need Rid Stiffs. Midstiff Smalls should be fine.

yes

The under-boot cartridges make for a much smoother power curve as you drop into a turn, let you carve harder, and grip the boot better. All around better binding, unless you're a very non-aggressive skier or do a lot of backcountry stuff.

You will want to mount on chord center. More info can be found here. www.telemarktips.com

That's a decent gauge. Mine hang about 2 inches, but obviously it depends on the stiffness of the cartridge. When your standing flat, snap the bindings on. They should be tight enough where the heel throw doesn't wiggle at all, especially away from the boot. Jiggle it with your hands and if it moves, tighten them.------------When your boot is strapped into the binding the silver sleeves should be sticking out 5-10 mm.

Regular.

It's an awesome binding for any skill level. Get the FreeFlex or Mid Stiff for beginning, step it up to the Rid Stiff when you get better.

Definitely the Rid Stiffs.

Anytime.

So it sounds like you're not on an especially aggressive setup (nice gear though), but you're not into crazy aggressive terrain either. I'd say you should get the Midstiff regulars, and then if they feel too sloppy, like it's all you pushing up out of the turn and the bindings aren't helping at all, upgrade to Rid Stiffs. Backcountry will let you return the old ones and shipping will be free on the new ones, all you'd have to pay for is to ship the old ones back. Probably a week turnover. If you do feel like pushing bumps and steeper terrain, I'd highly recommend Rid Stiffs. And kneepads, actually. I have the BD Telekneesis and they've saved me from many a rock (and my own skis).

The Midstiff is a fair bit stiffer than the Freeflex, and the Ridiculously Stiff is even stiffer. It really depends on your skill level. If you are just starting out teleing and don't have fancy boots or anything, go for Midstiffs. If the above is true and you weigh less than 120, go for Freeflex. I am 5'9", 145 lbs, I ski really hard (used to race) on pretty fat, 169 cm skis, and I have Scarpa T1s (very stiff boots) and the Rid Stiffs are awesome. The stiffer the binding, the harder you're going to have to ski them to get all the way down into your turn, but you'll be able to link turns much faster (hence racing). Less stiff bindings will be easier to drop into without being crazy aggressive, easier to hike in, but more strenuous for long days because they won't kick you back up as much. They'll also be easier to ski powder in because you won't have to balance your weight as carefully. The R and S refer to the length of the cartridges. I have a size 10 foot (don't know what boot length that is) and my ski shop accidentally put smalls on and I couldn't turn at all because the bindings got maxed out. Unless you have absurdly small feet, the R's will adjust small enough. Hope that helps. If you want more specific advice for your height/weight/setup, feel free to post another question and I can tell you exactly what to get.

The Regular cable will accommodate boots up to about a 400mm sole length.

compatible with all 75mm (duck bill) tele boots. Fact is, they fit super tight which means less slop and more control.
