One for the techies out there; what's the advantage/disadvantage of heel pivot bindings? Should you use the same DIN settings as with "normal" bindings? Idle curiosity based on having Tyrolia Peak fitted to Scott Missions. Wondering if they give me anything that "normal" bindings wouldn't.

Dr John, I have one pair of Fischer badged Tyrolias with the Diagonal heel and two pairs without. The only difference that I have found is that the heel on the Diagonal pair can twist sideways when putting them on if the skis are on a slight slope.

rjs, I had a similar problem the first couple of days, got used to it though, and a good sharp push down usually does the trick. I noticed that the release seemed to be more smooth that with regular bindings, and were more forgiving when twisted i.e. they allowed for correction when I got into a tangle instead of popping straight off. I'm impressed, all in all, but I'm by no means an expert in such matters.

Dr John, yes, with Tyrolia's you should use the same DIN dettings. The lateral movement on the Tyrolia's heelpiece is pretty minimal compared to the true Look/Rossi Pivot heelpiece so whilst they'll give more elastic travel (ie the amount your boot moves at the heel before the binding releases) I wouldn't expect any increase in knee protection versus conventional designs.

spyderjon, the original reasoning behind these types of binding was to put the axis of release (the pivot of the heel unit) directly below the tibial shaft so that they give better protection the the knee and lower leg

CEM, yep, I said that in the link above, & having the pivot under the knee must be a good thing. It's just that the Tyrolia heelpiece actually doesn't pivot that much before it comes to a stop & the boot can still be in the binding. Whereas the Look/Rossi heel continues to rotate until the boot is fully cleared of the binding.

spyderjon, although it doesn't rotate all the way it is still enough to reduce the forces on the knee by a good %
personally give me a binding with some sort of lateral/pivitol release in the heel over any other.... i knid of like my knees INTACT (trashed as they are)

It would be interesting to know by how much cause it doesn't show on my torque tester & AFAIK neither Tyrolia (or Look) have any put any figures on it.

spyderjon, i remember various figures being banded about back in the days of the look XM and the 99 RS but not since then and please don't ask me what they were ..i was young foolish and not good at remembering numbers....for what it is worth i am still foolish and not good at remembering numbers
placebo effect???? who knows ...i still feel safer in them than certain other bindings

Surely the whole point of an AFD is to do EXACTLY the same thing.
Look even stopped manufacturing a true Pivot binding for a while as their binding designers decided it was unnecassary in terms of release / injury safety.
It has been brought back by consumer demand. Placebo effect? Probably not. I'm *not* saying it doesn't have a smoother release, I *am* saying it's probably not safer.

And love to help out and answer questions and of course, read each other's snow reports.

The AFD is to aid a smooth release of the boot from the binding, irrespective of whether the pivot point is at the toe or heel.
AFAIK Look stop making the true pivot heel cause it was expensive to make & it's additional functionality apparently was no longer required when they upgraded their toe binding to include a vertical release function. Still, the idea of the pivot point being underneath the knee rather than at the toe seems to be a good 'un so arguably the safest binding on the market is their Pivot 14 as it has a fully functional toe piece combined with the fully pivoting heel piece. The Pivot 18, with it's totally bomb proof metal toe piece which makes it a favourite with mogul skiers, freestylers & big hucking freeriders is therefore arguably less safe for mortal skiers than the 14 as it doesn't have the vertical release function.

the other factor with the turntable heels was that the mounting points between toe and heel units were shorter and affected ski flex less

You know it makes sense.

thanks for the info all. CEM, completely agree with you that I do feel safer in the Tyrolias, especially since my range of skiing territory has increased and I took a few tumbles in powder/crud and felt like they released only when required. Placebo or not, they worked for me.
