Third season on the axles for more backcountry than resort. Love the binding's power in third position with spiffy springs. why not? You can free pivot on the way up. Do have to say I really loved borrowing my friends vector BC's mounted with Switchback two's the other day. I felt the switchback 2's had very similar power and feel, but the switch over was easier ( from tour to ski), and of course it's a lighter binding. Both american made which I like.
I will say I've got a pretty big repair kit for my axles that I never leave home with out. First off though, I never switch back into ski mode with out taking off the ski and cleaning out the ice or snow build up under the lock mechanism. Locked in, it's bomber, but if you force the bar forward into locked mode with ice present you are risking bending or breaking the attachment point to the lock bar. Not good on a 3-4 day trip...
So. I've broken a heel piece, I've lost the main pivot screw in front of the toe, and the rear transverse bar, the one I think the new crampon will be attached to, broke a spot weld at one end: I've replaced the pivot allen headed bolt with a regular 5/16" hex head bolt, with threads twice as long as the standard cap bolt. I did reassemble with a dot of epoxy, but I also watch it like a hawk.
I've also seen the power pin almost work itself out in use. I bought an extra pin, for that 1,2, or 3rd setting, but because that aforementioned rear most transverse bar which broke spot welds ( happening on both skis, I found), I use 1/4" bolts in the third setting, with double nuts on to keep from loosening and falling off. So I have the bolt tightened down enough to mitigate the transverse bar failure, and I keep the supplied power pin stored in the first hole just in case I need it. I'm using B&D crampons with a lock feature so I don't have to hear any clicking while climbing. The axle changed up my skiing. I love it, but would buy the switchbacks for the next boards.

Hi people, I've had the 7tm power tour binding for a couple years now, here in the North Cascades. When I bought it, it was the only binding that had the free climb feature ( so maybe I've had it for more than a couple years?) anyway, the free climb feature was essential, the release feature was comforting,I love the crampons, and I could deal with the weight. however, after a few years of use, not super heavy use (OK....about 12 times each year riding the lifts, about 12 times each year on long day trips, and about 10 days of ski camping backcountry trips), I have issues with the bindings.
OK, now the bad stuff.

There is too much side to side play in the binding in tour mode on the steep stuff. set at the proper binding tension, I still get my heel sliding side to side sometimes ( I do have a size 13 foot, though). A big negative is that in free climb mode, due to the binding and heel lifter being mounted to the foot and not the ski, the balance of the ski is not good for deep snow trail breaking. In other words, when you are high stepping in deep snow and lifting your foot, the tip does not come up / the tail does not drop. I've mitigated that somewhat by two things: first, I added two big washers taped to the tail lever of my skins to weight them down some. And second, I use some small bungie cord routed through the run away loop on the binding and then stretched up to my boot buckle, in an effort to ge the front of the ski to lift for me.
And now, I've got the stainless steel rivits coming loose on the little part that recieves the pivot pin and is mounted to the bottom of the (nicely heavy duty) toe piece. I can't seem to get those tightened up (by peening). and also, my pivot pins themselves seem to be wearing out.

Another problem I've had was easily fixed by mounting a couple sink faucet washers on each ski in the proper place to keep the heel lifter from slipping forward and collapsing from high position to mid high position when you least wanted that to happen.
The rubber piece that runs under the boot and attaches with one little tiny bolt always scared me too, so I carried extras in the field, but I never had one fail.
I do have to add that being able to buy an extra toe mounting plate for another pair of skis has been nice for me, and I use the same binding on my work skis when reading meters around town.

The power binding upped my skiing a notch, to be sure. Now I'm looking to go up again with the axl. I hope I'm not jumping the gun on that binding however, due to the fact I will be losing the release feature and it looks like no crampon either..

Hi people, I'm interested in the Axl, after three years of the 7TM.....I'm sad to see the Axl does not seem to have room for, say, a voile ski crampon...Am I wrong? Also, I sure hope that in climb position the ski tail will naturally drop for me when stepping tall through steep and deep snow. Had to weight my skin tails and bungie from the binding to boot on the 7TM to get them to behave in deep trail breaking mode. hope the 22 guys are thinking of a ski crampon that can be added on, it's needed much of the year here in the North Cascades.

thanks for your comments. cheers, bob
