Rows of cyclists getting cold (7)
I believe the answer is:
bickers
'rows' is the definition.
(bicker is a kind of row)
'cyclists getting cold' is the wordplay.
'cyclists' becomes 'bikers' (I've seen this in another clue).
'getting' means one lot of letters goes inside another.
'cold' becomes 'C' (eg on taps).
'bikers' placed around 'c' is 'BICKERS'.
'of' acts as a link.
(Other definitions for bickers that I've seen before include "squabbles" , "Argues over petty things" .)
