Technical Details

I acquired my Mammut Bionic Alpine Belay from CampSaver.com in 2017.

The Mammut Bionic Alpine Belay is 38 mm. long, 88 mm. wide, 71 mm. high, and weighs 76 g. It consists of two cast stainless steel pieces and a center plate riveted between two side plates. One of the pieces has two V-notches for the main line and a small accessory eye. Each V-notch has an internal rib on each side. These are offset to give a slight dogleg to the rope path. The other stainless piece provides a smooth running surface. The center plate has a 19 mm. round eye at the side opposite the V-grooves, and a 37 mm. by 37 mm. irregular hole below the rope channels.

Each side [plate is printed with a rigging illustration an "MAMMUT." The rigging illustration is continued by a hand holding a rope etched into each side of the notched steel cross-piece. One side of the center plate is printed with a carabiner icon and a filled triangle pointing toward the large hole, a book-with-an-"i" icon, "Ø7.5-10.5 mm," and "EN15151-2 UIAA." The other side of the center plate is printed with a carabiner icon and a filled triangle pointing toward the large hole, a carabiner with attached ring icon and a filled triangle pointing toward the round eye,and "BIONIC ALPINE BELAY 11-15."

Comments

The Mammut Bionic Alpine Belay reminds me of the Petzl Reverso, but with the Bionic Alpine, rope runs over steel steel blocks rather than the edge of an aluminum stamping. This alone is sufficient to make the Bionic Alpine a much superior device in my mind, and the addition of V-grooves to increase friction is a second significant improvement. Finally, the Bionic Alpine is lighter than the Reverso.
