Reflex white cuff + 840: play under the toe loop

edited May 2018 in Skis Fins Bindings
I just replaced the boot and the silvretta (new 840) on my reflex system. However the toe loop and carbon plate are original.

I am noticing (just during setup so far) that there is a good amount of play under the toe loop when the system is locked in at the intended tension.... I’ll post a video later today to show exactly what I’m talking about,

but has anyone experienced this?

I’m asking because I am gun shy from a handful of prereleases on my old setup, and want to make sure everything is as the manufacturer intended to be before I ski this summer.
Thanks :)

    I had play with it once.. about 6 prereleases later we found out the plate was too big. Are you sure they sent you the correct size boot? If there is wiggle room I would not put that ski on from personal experience

    Double check the bolts holding the toe loop in place are secure.

    Unfortunately you need to take the plate off the ski to inspect it. On Feb vacation I took a wicked OTF/pre-release fall because one of those bolts Had worked it’s self loose over last season.

    Long plate with size 12 boot

    There’s a video of the issue.

    The plate was purchased with an original black shell with silvretta 500 which had the 4 point connection on each arm as opposed to the current two point connection.

    There are 2 mounting holes for the arms on your release. Try the other set of holes

    @aupatking hey, I just switched holes ( I didn’t even see those earlier, they are kind of hidden) I believe this has fixed the issue, and I hope this short thread will help the next dinghead figure this problem out :)

    @KcSwerver – moving the release arm to the forward holes of its mounting block (as you did) may just be a band-aid remedy with regard to what you displayed in that YouTube vid. That’s a ton of loose play!

    It appears the distance between the toebar and release arm mounting block is too great. The release arm block can be moved forward on the plate by one pair of outer holes from where you have currently placed it (compared to those originally used for the 4-screw/side 500 mount). Good possibility that the new release arm blocks need to be mounted on the plate forward of those used for the 500.

    I’d leave the toebar in the “12” positioned holes, be certain the spacers are in use (it appears they are from the vid) and should be based on the prior setup for a "12".

    These threads always turn out trepidation. Get that set-up right; pre-releases are treacherous!

    @Gloersen any idea why the 2 holes are there, if not for the difference in boots? That plate isn’t the current reflex plate. All current plates only offer one position for the release mechanism, but all mounting blocks come with 2 holes. If he moves the release, it also changes the boot distance from tail, and you can see his plate is as far back as it will go. If you move the base pieces, it looks like you are going to have to lengthen your plate-to-ski slots and add holes.

    @aupatking - I've had to move the release arms up to the front holes in the block too on some setups. It just depends on how secure the release mechanism feels. That's always been just at the heel though (the clamp), never had a setup as loose as @KcSwerver appears (the whole boot isn't secure).

    I heat gun flatten the boot to sit on the plate through the toes, this tends to "lower" the position of the heel block and moving the release arm up to the forward holes of its block accommodates this. Also, I suspect with time and use, the boot naturally tends to flatten out compared to its new state, so it may be necessary to move the release arm then as well to get the clamp fitting snug again. Could be production variants come in to play as well.

    Regarding FB/tail, that will change no matter what the remedy; clearly the toe of the boot needs to move substantially forward to fit under the toebar appropriately. It may require plate mods (as you stated) to mounting holes for the range of FB distances sought. Another option would be to move the toebar back but that might be too big a move, though something to consider with that amount of play.

    These Reflex devices are intricate; when one starts mixing and matching components of different vintage, it requires a bit of experience, reasonable technical skills, and lots of vigilance.

    The most salient advice to offer is; be sure to know what one is doing and get it right.

    That was something I liked on the FM toe block version. You could adjust the toe block to get a good secure lock at the heel. Shifting the block backwards tilted the release rearward and increased pressure in the spring. There should be better set up data for ledge height and fore/aft alignment.

    I have a FM toe bar,, it can be used with Reflex, easy mod. Depending of how much you tighten the buckle, you can also change the boot placement a little, so it's better to find the optimum and leave e it there or put marks on the buckle teeth.
    Same thing when you move your silvretta to eliminate play.
    @KcSwerver I would try to use the stainless steel bases with the 4 hole and see if it would minimize play.
    SS bases holes can be slotted so so that you can move the release half a hole on the plate and if you do use those bases, do not use the front inside bolt, it is not nessesary and the nut dig into the boot heel.
