The invention relates to an assembly (1) of bicycle components in mutual rotation, like for example a bottom bracket assembly. The assembly of the present invention comprises a support element (15), a rotary element (5) rotatably coupled with the support element (15) and at least one bearing (20) arranged between the support element (15) and the rotary element (5). The bearing (20) comprises at least one bearing element (30, 40) firmly coupled with one from the support element (15) and the rotary element (5). The bearing element (30, 40) and the element (5, 15) with which it is firmly associated have, at respective mutually coupled interface surfaces (36, 38, 42, 44), a standard reduction potential difference lower than or equal to 0.3 V, in absolute value.
