Risk link cables.
6.66kg’s! Risk link cables saved another 40g. Last time I used a set of these super lightweight link cables was with some KCNC link cables back in the early 2000’s. I remembered that they were a pain to set up right, and yup, these Risk cables were an absolute pain to set up right too (I let go of the cable housing at some point and every single little piece scattered all over my floors lol). They’re also functionally not as good and brakes feel pretty mushy now, but hey the brakes work, saved some weight and the extra flexibility let me route them internally through the handlebars for a cleaner look.
