The Tec Step Bionic Turn 2 is Mammut’s top-end via ferrata set. It’s robust, handles well and has some brilliant features, but a swivel joint that doesn’t swivel enough and a couple of simple design issues mean that it isn’t perfect.

Two things persuaded me to buy the Tec Step Bionic Turn 2. The first were the strong safety claims made about it by Mammut. The second was the swivel joint designed to eliminate that annoying problem of your lanyards getting twisted during a climb.
Safety
Mammut states that that the Tec Step Bionic Turn 2 “incorporates the most recent findings from safety research” and that:
- the lanyards are of “an extremely strong and robust construction”;
- that the shock absorber that has been optimised to “brake falls even more gently and thus better protect the body”;
- that the maximum impact force of a fall has been reduced; and
- that it will still safely hold a fall “in the case of a 180 degree misuse” i.e. a fall when only one carabiner is attached to the cable.
