cap

I'm a little stuck... Click here to teach me more about this clue!

'surpass' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for cap that I've seen before include "Flat brimless hat" , "Set limit to price increase - of headgear?" , "International sportsman" , "Soft headgear" , "Limit (prices)" .)

I've seen this clue in the Evening Standard.
