Simple, but Dumb, Question

Excuse my ignorance...

Do cantilever and centerpull brakes use the same frame mounts? Or does a bike have to be purpose built for centerpulls?

Thanks in advance...

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.

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.

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

Thanks for the insight. It seemed a bit complicated to me as I tried to research it...

PG - there's no such thing as a "dumb" question here. Some may be complicated and require complicated answers; others may be simple and result it quick, easy answers. That's what is great about this blog - ask anything and lots of people out there rapidly respond with their expertise and experience!

Centerpull braze-on questions are certainly not dumb. Canti-post bikes are everywhere and just about any canti or v-brake will fit most of them. So you see similar looking braze-ons but, oh, they're higher, they must be for centerpulls. Great, I'll just buy some centerpulls!

"Which centerpulls do you have braze-ons for?" 😐

By coincidence, Jen Heine weighs in today on centerpull brakes:

No.

No dumb questions here. Someone just pointed out last week how there are so many standards that it's hard to pick one. If all the swirling ideas that reach manufacturing produce anything, it'll be questions. Even for brake mounting fixtures attached to the frame and fork.

Jan Heine (of Rene Herse Cycles, Bicycle Quarterly, reader and contributor here) just posted a blog entry about brake formats: https://janheine.wordpress.com

Not square on the head of your question, but enough context in the differentiation between cantilever and dedicated center mount post locations to answer it.

No dumb questions, but unhelpful subject lines. Something like "centerpull braze ons" or "frame mount centerpull" will help future listers who have the same question find this post. (And at the same time let current viewers have some inkling of what your post is about.)

Is there a way to change the subject line?

I wouldn't worry about it, PG, anyone searching "centerpulls" will find it.
