Measure abs peloton developed (10)
I believe the answer is:
tablespoon
'measure' is the definition.
(tablespoon is a kind of measure)
'abs peloton developed' is the wordplay.
'developed' indicates an anagram.
'abs'+'peloton'='abspeloton'
'abspeloton' with letters rearranged gives 'TABLESPOON'.
(Other definitions for tablespoon that I've seen before include "server" , "Piece of cutlery" , "Item of cutlery" , "One serves with this" .)
