Popular 24-strand rope that maintains firm, round shape but remains flexible.

Tachyon features improved grip and reduced hand fatigue, and will run well in hardware designed for 11mm ropes. Revolutionary Flexifirm Core Technology results in a lightweight 11.5mm climbing line that stays firm and round while permitting spliced eyes in one or both ends of the line using a double braid splice. The product's firm yet flexible design and superior strand definition significantly improve friction hitch performance without the "bagginess" that can occur with other 11mm ropes.

Good rope

by Samantha

This stuff is nice rope. It doesn't milk much. I find myself favoring this line on srt removals where I am using a foot ascender on my gaffs. It takes ascender use well and runs great on a rope wrench.
