I had a clearance that tight with my old IRO. It was fine, although that was aluminium and I am feeble.
The other option is to get a smaller chainring.
Edit: Unless you actually have the problem you describe and not the one that I thought you had.
You might have problems with your heels hitting the chainstays, though.
