Shimano SL-BS79 Outer Cable Guide

Shimano recommends the use of these SL-BS79 outer cable guides when you are running outer cables under bar tape (ie higher-end STI levers or bar-end shifters/brakes). They hold the outer cable straight and prevent the bar tape from causing any kinks or narrowing of the outer, which could affect shifting/braking performance. It is also useful for bars without cable grooves, as they help to retain the free cable movement but are also comfortable when under the bar tape.
