Italien rando racing gear manufacturer has used their long experience developing Dynafit “Tech” compatible racing bindings to good effect in the touring end of the market. The ATK Race RT weight just 170 grams, about half that of a TLT Speed. RT stands for Race Touring. A binding made for tourers who want to cover a lot of vertical, fast.
The binding offers usual lateral and vertical “DIN” release settable from 5 to 10 plus the toe release can be set. Interesting stuff, we don’t know if you can lock the toe for the steeps.
You can use a baseplate to allow for 3 mondo points of heel adjustment giving an all up weight of around 400 grammes incl. screws compared to around 700 g for the TLT speed. ATK are also going to release a ski brake.
So a number of interesting developments. Metal construction, none of those plastic parts that break when it gets cold. Especially interesting is the metal ski crampon holder and potentially better release characteristics in falls.
