Pubs supporting trade in bicycle components (10)

I believe the answer is:

handlebars

'bicycle components' is the definition.

'pubs supporting trade in' is the wordplay.
'pubs' becomes 'bars' (I've seen this before).
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'trade in' becomes 'handle' (I've seen this before).
'bars' put after 'handle' is 'HANDLEBARS'.

(Another definition for handlebars that I've seen is " Part of bike".)

I've seen this clue in The Times.
