The crossbar comprises an elongate, rigid tubular member having a groove formed within and extending longitudinally along the side wall thereof which is sized and configured to accommodate three cables of the bicycle. The crossbar is formed in a manner wherein the side wall, including the groove formed therein, is of greater thickness at its end portions. The crossbar further includes first and second cable receiving members which are rigidly secured within the groove and adapted to facilitate the entrance and exit of the three cables into and out of the groove.
