Talked of bicycle part (5)
I believe the answer is:
spoke
This clue is a double definition.
'talked' is the first definition.
('speak' can be a synonym of 'talk')
'bicycle part' is the second definition.
(I know that bicycle wheel part of bicycle)
'of' is the link.
(Other definitions for spoke that I've seen before include "Rung" , "Radius" , "Wheel's radial member" , "Uttered - bicycle wheel part" , "gave address" .)
