Plastic 'outer guide' included w/DA shifters...necessary?mizzou

Installing road shifters for the first time. When I removed the bar tape and old shifters, all I had was the cable housing running up into the shifter unit. Shimano included what they call an "outer guide" (white plastic w/metal end) that looks as though it should be snapped onto the cable housing and run up into the shifter. You then tape this guide down to the bar.

What is the purpose of this item? Am I okay if I just cut my housing, run it up in the shifter a few cm's, and tape it down?

I installed my first Dura Ace groupo last year (sans BB). Like you, I did not know what to do with Shimano's outer guide. My other bike that the LBS built up did not have them installed and neither did my wife's bike, but both bikes were built with an Ultegra groupo. Short story...I did not install the outer guides and the levers have been working perfectly.
Are you talking about the long white plastic piece.....Dave Hickey

that holds the brake housing to the bar? It's only purpose is really for comfort. If you don't like the feeling of brake housing on your hands when they're on top of the bar, this plastic piece smooths it out. I actually like grip better with the white plastic covering the brake housing.
