Sterling Evolution Helix 9.5mm x 60m


The Sterling Evolution series started it all back in 1993 with the release of the first 10.2mm instead of the then standard 10.5mm. The sheath and core construction of Evolution ropes are engineered for the ideal balance of low impact force, lightweight, and high fall ratings, all of which make these climbing ropes incredibly durable. The smooth sheath produces less drag through gear and over rock, allowing for an easier clip. Tested worldwide under extreme conditions, these ropes continue to prove to be the right rope for any climb.

HELIX 9.5mm
Small but mighty: With an improved sheath construction and bantam weight core construction, the Helix is Sterling's skinny workhorse. Blending the right features - the ease of the 9.5 diameter rope, durable and light with low impact force - the Helix is ideal for high-end sport, trad and mixed climbing.
