View Full Version : Snowjam ExtremeII Bindings

Switched from snowblades to EMP's this season and tonight was my first chance to get out on them with the warm weather. I set them up with some ExtremeII's having been a long time skier and not sure of myself with the nonrelease so I went cheap. I got what I paid for.

I listened to many of you and went and got loctite before locking in the bindings and then sized up my boot. My sole measures at 13.5 inches meaning my sole is near the top the EII can handle. 343 out of 350.

I'm not a small guy at 6'2" and 225lbs so I knew I'd need to put some elbow grease into tighening these things, so I did.

It started off well and had gone down about 2 dozen runs when I noticed on the lift that when i shook my feet one of my boards gave a little. I didn't think too big of it since it never seem to get any worse.

As time went on I hit some small man made jumps as I haven't jumped before and wanted to start off small. Had done quiet well and the bindings held up nicely through them...well until I decided to actually go just a tad faster and higher, that's when it happened. I found out why you should use leashes.

I started to land the jump and was putting my weight on both feet but noticed one foot didn't have a board under it, yup there it went down the hill without me....and i bit it hard, nothing really damaged but my pride and a sprained finger.

After it happend I figured the bindings had come loose from the boards and the loctite didn't do it's job, nope I was wrong. It was the bolts holding the adjustable pieces in place that had come loose, in fact they had come completely loose and thats why when I hit the jump it didn't come with me.

After getting back to my truck and pulling out the allen wrench that comes with the bindings I tightened it back up, but decided to check the other bolts. Low and behold all, yea both on each board had come loose and the other board was getting close to doing the same thing! OUCH!

In all I had been out about an hour and a half when this happened. Sure to say I am not pleased with my purchase at this point.

I am going to give it another try, but if this type of thing becomes typical out with them and FF or Bomber here I come.

If I was to score these bindings out of 10 I'd give it a whopping 5 at first trial. Maybe I didn't tighten them enough and will find out in the next trip and probably adjust my rating, but as of now: :mad:

my guess is you didn't tighten them enough. that's almost always the case, it happens with all bindings. you set them up when they are nice and warm and when metal gets cold it contracts and now the screws are a little loose and it works itself from there. first time out bring a wrench and tighten everything after the first one or two runs. after you get 'em tight when they are ice cold they should be fine.

Ahh great to know, I ever thought of that last night, was just too pumped to get out on my EMP's and get some carving in. I'll make sure to double check that next time, especially if i feel something losen up. Thanks Greco

If you do upgrade to better bindings, it might be worth mentioning that the FFPro has engagement teeth on the adjustment, so they set up very positively, and dont slip untill they are so loose that you would have to be brain dead not to notice. I dont think the Bombers are made that way. The FFPros are also discontinued, so if you want a pair, grab em now or weep later.

yeah we'll probably be sold out of them before the season ends.

I am not sure what the "official" recommended torque for mount bindings is, but 105 inch pounds (NOT foot pounds) has worked well for me. I have mounted composite risers to EMPs and SJ90s with this torque and have used the boards in the mountains for 5 days and locally for one without any loosening or retightening required. Note that my bindings have been modified and do not use the supplied flat head screws that go into countersunk holes. Rather I use pan head screws and washers. This may be why I have been able to go to the high torque of 105 in-lbs without damaging the risers.

If you are nervous about going all the way up to 105 inch pounds, start with 75 inch pounds which is the normally recommended torque for a M6 bolt.

If you do not have your own torque wrench, check if your local auto part supply store will allow you to "rent" one from them. One local chain in my area rents them for free, just need a deposit.

105 inch pounds relates to about a grunt and a half :-)

You guys are bumming me out; I just got the same set up (EMPs with Extreme II's). I only paid $50 for the bindings, so that makes me feel a little better, but I still don't like what I'm hearing. Is it worth all of the money I have left to upgrade? Note that this is my first year on real skiboards (I've been skiing for several years and snowbladed last year?

I did the same thing and only paid $50 for the bindings as i wanted to go cheap not having done nonrelease before.

But Greco is right, I should have brought my wrench with me and tightened them up after they got in the cold, that is a lesson learned by me. So now you should just follow his advice and don't pull a me and I'm sure you'd be fine with that setup. I plan on shreddin' that same setup next week, and the week after, and the week after, up until I find out that I like non-release then I'll probably upgrade, but that's me.

i took my new boards out for the first time a couple weeks ago... got out there for about an hour and felt one loosening up... i went back out to the car and tightened them up as hard as i could. i was on them the rest of the day wiht no problems... as greco said, the tempature caused the metal to shrink and allow it to loosen up. i doubt i can loosen mine now that they are in my warm apartment....

I took my boards out with snowjam extreme II's and ran into no problems. I did about 10 runs with them, then went into dinner leaving them outside. I went to tighten them after I came back outside and only one of the allen bolts was even slightly loose. The bindings themselves held up great and I had no problems all night.

yes, dave, it should have been in a plastic envelope with the leashes and instructions. if it wasn't please accept my apologies. the wrench (5mm allen) is very inexpensive and can be found at any hardware store. i'll include a link below so you can see a picture of it. if you find it locally and want us to reimburse you please let me know.

regards,

greco

OK G No Problem.

I didn't get any leashes either. Guess I'll have to use old boot laces!

OK Greco,

Don't bust a gut over it.

I'm in Meribel on Saturday, so I'm sure I'll be able to pick up some leashes there. And as you said, allen keys are easily available.

Lets just say you owe me a drink.

Cheers Dude.
