Ive recently bought a CX bike with Maxxis Raze 700x33 tires on it with installed cantilever brakes on it. The brakes are okay, but don't feel the best when I am trying to stop from speed so I am thinking about converting to caliper brakes. Do you know if caliper brakes would support this width of tire? I have measured the rim and they would fit that, I am just a bit worried about whether they would fit the tire?
As long as the froame/fork have the mounting points in the correct location then you should be fine. I've converted a couple of bikes this way and haven't had any issues with tyre width.
Hope this helps.
