Show Description

An extraordinarily thin and light single rope to suit sport climbers tackling ambitious routes. With a high sheath proportion for such a thin rope, it's the longest-lasting rope in its class. Because it meets testing requirements for single, half and twin ropes, it's a versatile option for alpine climbing.

  • Meets all standards for single ropes, as well as half and twin. Specs display results of single rope testing.
  • SuperDRY treatment covers both the core and sheath to provides protection from the damaging effects of water and dirt. Great for wet and dirty conditions.
  • Finishing treatment coats the individual fibers to reduce friction against each other during a fall, it also increasing durability.

Type Single (‹ 9.6mm)

Dry ropes have a water-resistant treatment on both core and sheath. Dry (UIAA certified) ropes have both core and sheath treated, plus meet the UIAA Water Repellent standard by passing a stringent test where a soaked rope cannot absorb more than 5% of the rope's weight.

Dynamic elongation

Maximum elongation in the first UIAA test fall, where a weight is attached to the rope and then dropped. Higher numbers indicate stretchier ropes.

Static elongation

In controlled tests, a weight is suspended from the rope (not dropped). Higher numbers indicate stretchier ropes.

Impact force

The amount of force, in kN, that the first UIAA fall puts on the falling object. Less impact force puts less force on the climber, belayer, and protection during a fall.

Linear weight 51g/m
Diameter 8.7mm
Halfway pattern change No
UIAA fall rating

Indicates the number of consecutive falls a rope withstood during testing in a controlled environment. The number is for reference only, and does not indicate the number of falls a rope will withstand during actual use or over its lifespan.
