In General.. a more durable wheel with a 32 tire will fit easily in Cyclocross frames .
and the same function well even when mud plugging... nature of cantilever brakes also benefits as there will be plenty of room
for mudguards .

in the space left .. that was put there to keep the wheels turning ..
when having an extra inch or so thick of mud sticking to them.

better still when the pros make disc brakes fashionable ,
the bike companys will make more for the rabble like that.
