<P>PROBLEM TO BE SOLVED: To provide an assembly of bicycle parts in relative rotation, (for example a bottom bracket assembly), ensuring an excellent motion smoothness for a long period. <P>SOLUTION: The bicycle part assembly is provided with a supporting member 15 and a rotating member 5 rotatably connected to the supporting member 15 and at least one bearing 20 mounted between the supporting member 15 and the rotating member 5, wherein the bearing 20 has at least one bearing elements 30, 40 strongly coupled with one of the member of the supporting member 15 and the rotating member 5, and the bearing elements 30, 40 and one of the member of the supporting member 15 and the rotating member 5 strongly coupled with the bearing elements have a standard reduction potential difference of 0.3 V or less on interfaces 36, 38, 42, 44 on which they are coupled with each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
