Z wypowiedzi wynika, że są dwa rodzaje łączników u blacka. Jedne dają raki sztywne a drugie nie.
"Rafal's crampon looks to have broken in a classic metal fatigue manner. Flex any crampon rail for enough cycles and it will break regardless of who makes it. The Sabretooth Clip comes equipped with a rigid center bar for steep technical climbing with rigid soled boots. Other models of crampons we make (Contact, Serac strap, Neve) come with flexible center bars for trekking or hiking boots with flexible soles. I have seriously considered putting flex bars on all of the Clip style crampons because the plastic toe piece allows them to be put a lot of boots that are less than appropriate.
If you use a flexible boot on crampons with a rigid bars it will shorten the life of the crampon because the metal takes all the stress as the boot flexes. The only type of crampon that can make a flexible boot rigid without sustaining fatigue damage is a vertical railed crampon like a Grivel Rambo.
Rafel states on his blog - - "Most usage has been on Scarpa Escape sz. 43 boots as walk-about crampons for photography purposes. Also used by my wife (in the same boots) for ice / glacier walks a few times."
The Scarpa Escape is a flexible trekking boot not a rigid technical climbing boot. While it is burly enough for use with walking crampons with flexible center bars like the Contact or the Serac strap, it is not appropriate to use with a crampon with a rigid center bar.
So Rafel, if you plan on using this boot with your replacement Sabretooths use the flex bars instead of the rigid bars or you will eventually run into the same issue. If you need a pair of flex bars I will send them to you, and I will make the crampon instructions more clear in the future as to what bars to use with what boots.
With the demand for lighter and lighter products there not a lot of buffer when you combine products that are less then an ideal combo."
