Teufelberger tachyon Ash Climbing Rope

Teufelberger tachyon is a light, low-stretch 11.5 mm climbing rope, and the ash color gives it a more subdued look than the brighter versions. Climbers pick tachyon when they want a smaller line that saves weight on long climbs and still works with common SRT devices and hitches.

A light line for everyday climbing

Rope weight adds up on big trees, especially when you are carrying a long access line plus a second rope for a redirect or rescue. tachyon's 11.5 mm diameter cuts weight compared with 13 mm lines while still feeling solid in the hand.

Low stretch helps on SRT, where every inch of bounce is wasted effort. It tends nicely through a hitch-climber pulley and runs well in many mechanical devices, which makes it a versatile all-day line.

The ash color is subtle and looks clean in the canopy, and it is easy to pair with a brighter line if you climb with two ropes and want to tell them apart at a glance.

Setup and care

Confirm every device and hitch in your system is approved for 11.5 mm rope, and fine-tune your hitch on the ground first. Compare other 24-strand climbing ropes if you want a thicker line.

Store it in a rope bag away from sun, fuel, and oil. Inspect the whole length for cuts, glazing, and core damage, and retire it per Teufelberger's guidance. Life-support gear must meet the applicable standard, follow ANSI Z133 and the manufacturer's instructions, and be inspected before every climb. Get trained before you rely on it.
