Setter blocked in by bus before lunchtime, cycling in Romanian city (5)

Ross

I believe the answer is:

'romanian city' is the definition.
(city in Romania)

'setter blocked in by bus before lunchtime cycling' is the wordplay.
I cannot quite see how this works, but
'setter' could be 'i' (the person that set the crossword) and 'i' is found in the answer.
'lunchtime' could be 'i' (1pm could be I on a clock with Roman numerals) and 'i' is located in the answer.
an anagram of 'bus' is 'sbu' which is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...

'in' is the link.

I've seen this clue in Independent.
