Boot sole / binding length

post #1 of 12
Thread Starter 
In boots, I went down 1 shell size (6 mm on the sole). If I shorten the binding myself using the adjustment wheel and visual scale, do I need to worry about having a shop re-check everything?

You are way off. Take them to a shop and get them to do it before you break yourself.

So even that small of an adjustment throws the DIN's and everything out of whack? I thought I was being overcautious to ask, but I guess not after all.

It doesn't throw everything out of wack but talking about an 'adjustment wheel and visual scale' it sounds like you don't know what you are doing and are adjusting the wrong thing.

OK, now I have the schematic in front of me for Marker AT w/ PCOS... they actually call it the "adjustment dial", between the toe and heel cups. The visual scale I referred to, they call the sole length scale - just the ruler thing with tick marks in 6 mm increments.

So as far as those things go, I'm pretty sure I've got it figured out - but just wondering if there's more to it. The best analogy I can think of right now is - suppose somebody changes the size of their wheels, but doesn't think to re-calibrate their speedometer.

Sounds like you have Speeddial Markers. Just adjust that to your boot length. Pretty much a no brainer.

You may need to double check the forward pressure, which is set via the screw in the back. The dial is only to make the "gross" sole length setting. From there you tweak the forward pressure screw as needed. In most cases little to no forward pressure adjustment is needed. The instructions should tell how to check the forward pressure, basically the forward pressure screw head should be flush with the housing when the boot is clipped in.

Does the forward pressure screw require a specially-shaped socket? The only traditional screw I can find on the back of the heel is the DIN screw.

"suppose somebody changes the size of their wheels, but doesn't think to re-calibrate their speedometer."

pretty good analogy. If the boot sole length gets shorter, the amount of torque needed to release the binding gets greater, therefore you may have to increase the DIN setting if the 6mm change moves you to the next level.

Also, what Phil referred to as the speeddial, is the rental system. If there is a dial in the middle with boot sole length numbers around it and a silver lever that pops the dial up so you can rotate it, you have the speeddial. That binding doesn't have the screw adjustment for sole length that skier219 spoke of. The dial setting is not that accurate, not sure why some 305mm boots measures differently than another brand's 305mm boot, but sometimes it does, and you will still need to check forward pressure. IIRC, there's an arrow and a plastic piece that pulls in when the boot is inserted. Arrow needs to be within the marks.

I think I have a Frankenbinding! I don't have the dial w/ lever that pops up and mm numbers around it; my lever pops out to the side and numbers are read under the toe cup. Yet, I don't seem to have a fwd pressure screw. Below the heel DIN screw is a nub that is roughly semi-circular, with an arrow on top. After shortening the binding, this arrow seems to be ever so slightly more flush with the housing. I've practically gone over it with a rectal probe, but the only screw is the DIN.

BTW, I have a schematic with "user instructions" that say all adjustments "should exclusively be made by an authorized dealer." To stretch the analogy, does that mean I have to go to the dealer to put air in my tires?

I'm not familiar with that binding, but it does sound similar to the speeddial. The lever on the speeddial does pull out to the side, and that pops up the dial. it also has what you describe as a nub with an arrow under the din adjustment screw, this arrow has to fall within a specified marked area when the boot is in the binding for the forward pressure to be correct. bad news/good news.... I can't tell you exactly what that marking looks like/ but it's usually fairly intuitive....

Thanks everyone for all the info! I'm pretty sure it's squared away. My shop won't be open on the way to the mtn., but I can stop in on the way back to double-check things.
