Shiver cycling racers in Yorkshire town (12)
I believe the answer is:
huddersfield
'town' is the definition.
(I have seen 'northern town' mean 'huddersfield' so perhaps 'town' could also mean 'huddersfield')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for huddersfield that I've seen before include "West Yorkshire town with famous choral society" , "W. Yorks town with famous choral society" , "Town within the Metropolitan Borough of Kirklees" , "northern town" .)
