I'm currently looking at cx frames right now and I've got a problem. For all the bikes I've seen, they only have a 46/36 or 48/38 chainrings on the crankset. Now I don't know if they are able to accept a larger chainring or not, but I've been looking at alot of frames like the Specialized Crux that present no info about max chainring size.

Any way you can help me out?

My assumption is that there'd be no problem with clearance of the big ring or adjusting the derailleur. I currently run 53/39 on one cross bike and 50/34 on the other.

There is no max chainring size. I've had many cross bikes and each of them at one time or another has has a standard double mounted on them. 52/39. No problem.

Actually, some cross frames do specify a limit for chainring size because of chain stay interference. On the other hand, I've been looking at them recently. My advice to OP is (1) look at other versions of complete bikes that use the frame or similar frame to the one you're interested in. Many times a frame that comes in a "real" cross crankset (e.g. 46-36, etc.) will come in a road triple or a road compact double in another version. THerefore, you can be confident that they will accept a road triple or road double. and (2) just contact technical support for the bike company. They'll tell you outright.
