Ropes supporting clever, arrogant chaps (4,4)

I believe the answer is:

wise guys

'arrogant chaps' is the definition.

'ropes supporting clever' is the wordplay.
'ropes' becomes 'guys' (I've seen this before).
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'clever' becomes 'wise' (I've seen this before).
'guys' put after 'wise' is 'WISE GUYS'.

(Another definition for wise guys that I've seen is " Smart Alecs?".)

I've seen this clue in The Telegraph.
