New strap in bits (5)
I believe the answer is:
parts
'bits' is the definition.
(I've seen this before)
'new strap' is the wordplay.
'new' indicates anagramming the letters.
'strap' anagrammed gives 'PARTS'.
'in' acts as a link.
(Other definitions for parts that I've seen before include "Strap (anag.)" , "bits" , "Components of strap" , "Leaves" , "Areas" .)
