Mammut Bionic Alpine Belay - Innovative and ultra-robust belay device based on the tube principle. The brake ribs and the rear rope contact surface are made of abrasion-resistant steel, which prevents grinding in through rope friction and the associated critical sharp edges. The housing, on the other hand, is made of lightweight aluminium, which means that the total weight of the device is just 80 g.
Suitable for twin, half and single ropes with a diameter of 7.5 to 10.5 mm.
