Ultra light, strong and low stretch, this is the best backstay available for the T10. The core is heat-set SK99, covered with a thin cover made of Dyneema Black. An eye splice at one end, and a low friction ring at the bottom. This is actually smaller and lighter than the original Dux backstays originally specced with the T10 class rule change, but fully covered for chafe and UV resistance.
This is for the standing backstay only, the Complete Kit is also available
