Cypher

Strong, easy-to-use ascender works on muddy or icy ropes

Cypher's patented Chest Ascender is strong, works on dynamic ropes from 8mm to 13mm (10mm to 13mm for static ropes) and comes with a patented lever that, when suppressed, allows for safe and easy downclimbing without removing the ascender from the rope. The rope cam is designed to hold even on dirty, muddy or icy ropes.
