Generally smaller (56 / 57 / 58), but there's enough variation in how bike sizes are specified across vendors and also enough variation in people's body proportions that a more specific answer is hard to give you.

I agree with Chris. For example, I ride a 54 road bike (Specialized Allez Pro) and a 51 tri bike (Cervelo P2 SL).

Top tube length and stem length will matter quite a bit, too. You might have to swap stems in order to get a proper fit.

Funny, both my Allez and my Transition are 54's, and both feel great. This is however, after a lot of time on the trainer, and trying different sizes, brands, etc. and a proper fitting at the LBS.
