It's hard to say without seeing you on the bike but someone 5'6" typically rides a frame larger than a 49cm. According to the listed specs the top tube length is 51cm, a top tube this short has a very short front center (thus the overlap). Sounds like a 51 would have been a better fit.

At any rate, the only things you can do at this point is try shorter cranks and/or possibly install a fork with more offset. The cranks are the obvious choice; I wouldn't mess around with anything shorter than 165's as the others have stated. The fork is an expensive undertaking and may not be worth the expense. The 555 comes with a 43mm offset fork, which you could change over to 45mm without messing up the handling.

Shorter cranks = 7.5mm extra clearance
45mm rake fork = 2mm extra clearance (not much difference)

Sorry, there is no other solutions I can think of.

Good luck.
