The 640g Onyx has a DIN range of 6-12 and has been revised this year to include some new features. The stainless steel toe pins now include ice-cutting serrations to ensure good contact with the boot, along with a new toe lever that requires less force and includes a soft insert for easier activation with your pole. Two pole-actuated heel lifts allow you to easily adapt to varying terrain on the fly and the ski mode lever does the same for the selecting between ski and tour modes, though the lever for ski mode takes slightly more finesse to engage. For added versatility, the toe and heel pieces are easily adjusted or removed from the mounting plates. Adjust up to 33mm for differing boot sizes or pull the entire binding off to use on different skis or to make travel easier.
