Your bike was sold with 23's.
I was able to squeeze 28's on to my Felt F-85.
It depents on your frame, brakes, rims, and tires.
I have a set of 28's that measure 27 on one rim and 30 on another rim.

The only way to know is to try some.
Find someone that rides with 28's and see if you can fit their wheel on your bike.
