Mammut Bionic Alpine Belay - Innovative and ultra-robust belay device based on the tube principle. The braking ribs and the rear rope support surface are made of abrasion-resistant steel, which can prevent dragging due to rope friction and the associated critically sharp edges. The housing, on the other hand, is made of lightweight aluminum, meaning the total weight of the device is only 80g.
Suitable for twin, half and single ropes with a diameter of 7.5 to 10.5 mm.
