Purpose-built. Centerpull and cantilever braze-ons are in different spots.

Excuse my ignorance...

Do cantilever and centerpull brakes use the same frame mounts?



Yes and no.  Paul Racers use standard (i.e., Mafac) cantilever posts.  
Other centerpulls (Mafac, Diacompe, ReneHerse) use a mounting post that 
is different from a cantilever post.




Or does a bike have to be purpose built for centerpulls?



Yes,. for braze-on centerpulls.  Regardless of whether the post is the 
same or not, the location of the post is very different for centerpulls 
vs cantilevers.


You can, however, use a bolt-on centerpull on a bike equipped with 
brazed-on cantilever posts, if there's a center hole.
