This low-friction cable system from Gore features an outer sheath that protects the inner wire between cable stops and Gore’s Grub Seals to keep out performance-robbing dirt and moisture. These are the same cables as those now supplied with SRAM Red components.
Reports from mechanics in the field indicate they work extremely well, while being as easy to fit as conventional cables. That’s an improvement over Gore’s superb but somewhat fiddly Sealed Low Friction cables. The result is a silky smooth system that stays that way for a long time.
