I'm upgrading an old Trek with 6603 drivetrain and my first real excursion with brifters.
How important is the #15 outer brake cable guide? Should I seek these out or just use the outer taped on like older aero cable routing? Do I want (or need) a ferrule on the end of the casing that slides up into the lever?
Is there any really any elegant way to run the shifter cables from the levers to the DT stops? I know I don't want any sharp bends and need to be able to turn but it is kinda fugly looking. Maybe I'm just too used to not seeing so many cables up there.
