Fellow setter out cycling shows spirit (7)
I believe the answer is:
manitou
'spirit' is the definition.
(I've seen this before)
'fellow setter out cycling' is the wordplay.
'fellow' becomes 'man' (fellow can mean a man).
'setter' becomes 'I' (the person who set this crossword).
'cycling' indicates anagramming the letters.
'out' with letters rearranged gives 'tou'.
'man'+'i'+'tou'='MANITOU'
'shows' is the link.
(Other definitions for manitou that I've seen before include "Native American evil spirit; out main (anag.)" , "Brave spirit" , "sacred object" , "Algonquian deified spirit" , "N American Indian spirit" .)
