Nube tech question re: binding adjustment

post #1 of 9
Thread Starter 
Don't laugh. I've always had "the shop" adjust my bindings, but this seemed so simple even I could do it. Just bought a pair of Krypts which have a 306 sole. My current Tecnica Xt's are a 303. Bindings are the default that come with the Blizzard Titan Cronus - Markers in smal letters. So I put the old boots on the skis and observed the tolerance of about 1/8" between the heel and the part of the binding heel that captures the boot when secured. I then turned the adjusting screw on the rear of the binding heel until I got the same tolerance with the new boots. Put the boots on and tried the binding several times. Feels secure with the binding cuff firmly around the boot heel. Sound right? As for the toe, is there any adjustment that needs to be made? The XT's had riser plates on the soles while the Krypts don't. Not sure if that matters. Again, with no toe adjustment, boot toe fits firmly into toe piece. Sound OK? Would any of these adjustments throw off the DIN settings or release criteria? Much obliged.Tx. David

You are probably not going to find anyone willing to assure you over the internet that your bindings are adjusted properly. It sounds like you are on track, and the basic adjustment for forward pressure is that the adjustment screw is flush with the back of the binding, but new boots with different size soles may not release the same as your old boots. Toes pieces don't all work the same, some are height adjustable and some not.

Since you are not trained or experienced you really should have a shop machine check the release. The other option is to take the risk of ending up thinking about the $25 you saved while in the hospital bed due to your bindings not properly releasing. With all the $$ you spend on skiing, having your bindings checked is the smartest and cheapest investment you can make.

OTOH, when I got my Kryps I had the same problem, adjusted the forward pressure on one of my sets of binding bindings, had them checked by a shop and they were fine, and then adjusted the binders on all the rest of my skis myself. I have been skiing for 3 seasons with no problems, but I would never advise you to do that.

From your understanding of a binding I would in no way recomend you ski on these without getting them adjusted by a shop. Do you know what forwards pressure is, if not, do not pass go, return to ski shop.

Not being mean, just concerned for your own safety.

In all fairness, if you did nothing at all the binding should have been ok, as 303mm sole to 306mm sole is a tiny adjustment (1/8th of an inch in american) and would probably result in the same positional setting, but it may be one click different.

To be honest, the bindings may have been fine they way they were -- 3mm is not that much (on many heel pieces, the forward pressure increment is 2 or 3mm). But either way, don't eyeball the fit between the boot and heel piece, because that can look fine and still result in the wrong forward pressure. You need to gauge it by looking at the forward pressure indicator. On that binding, you want the screw to sit flush with the housing as mudfoot noted. Snap the boot in, look at the forward pressure, then release the boot to make adjustments. Repeat as needed. From a 303, a 306 should not take very much adjustment at all. Good luck! Dang lawyers

Hey, I'm one of them "dang" vampires - your term if memory serves...Off to the shop for the adjustment. Thanks for being the voices of reason. Guys just want to take of their own sh*t - but not from a hospital bed. On the slopes on Sunday to try out the new Krypts. Sugarloaf is open till May 4 - and it is going to be 60 degress tomorrow! That's what a 250" year will do for you. Tx buds. David

I don't think "vampire" was my term, but I was referring to *you* when I said "dang lawyers"! (Feel free to call me a dang engineer anytime). BTW, I am not advocating a shop visit myself, since in this case it should be simple to verify that the fwd pressure is OK. That said, a shop visit can't hurt.

So after getting paranoid from your collective good advise, I went over to my local shop and the tech there put the baords onto the bench and showed me how to do the adjustment. Just put the boot in the binding and turn the adjusting screw until it is flush with the housing. Just like mudfoot said. No toe adjustment necessary. Dang easy. Now I know. Tx. David

I think you'll be fine as long as the tourists stay off your skis. You got a new helmet don't cha?

Ya' baby. Got a Bern G - nice fit but chilly in the back because the vent holes do not close. Will have to patch them up. Thanks for thinkin' of me and my knee. I really dodged the bullet on that one - just didn't quite dodge the shooter. Was sure that I had damaged the medial meniscus. But after a month, the pain was mostly gone. I went out for half a day and then a whole day a week later. Back to normal. Thank the ski gods. Ya know I started taking a chondroitin/glucosamine/MSM supplement a few weeks before this injury, and throughout my recovery. Can't help but wonder if that aided in such a speedy recovery. Had a strain of the lateral collateral ligament with the other knee doing some snowshoe bushwacking. Again, thought it was blown, and was back in shape in three weeks. I got 51 yo joints that feel as springy as they did when I was a pup. I think there is something to that concoction. Tx again bud. Happy summer. David
