Just finished putting on fresh cables and I chose Jagwire Elite shift and brake cables/housing for a Tarmac SL6 rim brake.
I’m not a fan of the coating on the DA cables. It’s great at first but ends up a mess. Optislick is my choice from Shimano and a good value.
Jagwire Elite isn’t cheap but the details are worth it IMO. The extra flexible section on the brake housing was a godsend routing through my aero road bar, and the ferrules and extra pieces are top notch. I also like their compression free brake housing. It cuts cleaner than spiral housing with no burrs.
Of course they shift as well as anything out there, too.
