Getting a cab, rode off with the stuff (7)
I believe the answer is:
brocade
'the stuff' is the definition.
(I have seen 'Heavy stuff' mean 'brocade' so perhaps 'stuff' could also mean 'brocade')
'getting a cab rode off' is the wordplay.
'getting' is a charade indicator (letters next to each other).
'off' indicates anagramming the letters.
'cab' put after 'rode' is 'rodecab'.
'rodecab' is an anagram of 'BROCADE'.
'with' is the link.
(Other definitions for brocade that I've seen before include "Rich material" , "Rich silk fabric" , "Heavy silk fabric with a raised design" , "Fabric woven with raised patterns" , "Rich fabric with a raised pattern" .)
