This ultra-light pin binding (245 g w/o brake) offers active length compensation when the ski flexes and an impressive power transfer downhill due to a 38 mm drill pattern. A carbon-reinforced toe provides great stiffness and comes with anti-ice pads and integrated elastomers for easy stepping in. The heel features a climbing aid with 0°, 5° and 9° angles and can be quickly and easily switched between hike and ski mode. Another useful feature is that the Alpinist allows a +/- 7.5 mm heel adjustment to suit various sole/boot lengths.Specifications:- Din/ISO Range: 4.0 - 10.0- Recom.
