Show Description

The nForce uses a 4-bar linkage that forces a climber's weight onto the rope and results in 33% more clamping force than any other ascender. A welcome tool on icy or muddy ropes. The cam is easily operable with your thumb, index finger or the edge of the frame.

  • Moulded rubber grip for comfort and warmth.
  • Clip in point allows a locking biner to be fully rotated.
  • Fits 8 – 13mm ropes.
  • Sold individually.
