<p>A control lever mounting system (10) includes first (14) and second (16) boss members, each shaped to receive a control lever (62) thereon and having a bore (32) shaped to be positioned in registry with a transverse hole (40) in a bicycle frame tube (12), and a connector pin (18) for joining the first and second boss members together. The pin is shaped to extend through the tube hole and includes opposing end segments (34, 36) shaped to protrude outwardly from the hole and into the bores (32) of the boss members, forming an interference fit, such that the pin holds the boss members against opposite sides of the frame tube. The boss members each include a recess (28) formed on an inner face (24) thereof shaped to receive adhesive (30) for attaching the boss member to the outer surface (26) of the tube, thereby providing means of attachment in addition to the press fit engagement between the boss members and connector pin. To assemble the control lever mounting system, the connector pin is placed within the hole of the frame tube, and the boss members are then pressed inwardly against the tube so that the ends of the connector pin form an interference fit with the bores of the boss members.</p> |
