is there a good (read: cheap) way to go from a caliper brake on the back wheel to cantis? at least, without undertaking in an amateur welding project?
or at least a way to fit a 700x30 tire or bigger?
well, if your frame has the clearance and it's just a brake issue, you could use a bmx caliper. they handle pretty fat tires.

shoot up or shut up.
you could also try an old center pull brake by mafac or weinmann or dia-compe.
that's what someone IRL suggested to me, so i think it's what's going to be tried. My cycling team is trying to build a fleet of starter cross bikes that we can turn back in to road bikes in the spring.
