Production frames with Centrepull brake posts
 

Anyone heard of them? I've seen tons of boom bikes with centrepulls mounted on an extra back plate, and gorgeous custom frames with centrepull posts brazed to the frame, but never a production bike with posts. Am I missing something? Point being is that almost all bike writers in the know rave on about the brake qualities of a set up like this... (And I've a great pair of MAFACs burning a hole in my parts bin).

The centurion pro tour is one.

In fact that's the only one I've ever seen. Probably the very same one.

Hire the frame you like modified by a frame builder then , then get a repaint.


The vast majority , were bolt ons to keep the cost down.

I thought I'd seen one or two others, but I can't think of one.

I'm pretty sure one was a randonneur Veloflex model.

Raleigh International? My 74 has a brazed on post for the center pull brakes.

No, it doesn't. Beautiful bike, though!

Here are the posts on my 1977 Centurion Pro Tour with the original Dia Compe Model G brakes. Notice that the front of the fork crown isn't drilled! The rear side is tapped, which keeps the front looking sort of unique. I've also modified one of the bolts on the front to hold on my dynamo powered lamp, since there is no hole in the fork crown...

These types may be seeing something of a re-emergence in custom bikes since Paul's Components started making the Racer brake. I have a set of the conventional mounted ones, and they're nice brakes.

If the posts are in the same location you may want to look at frames designed for rollercam brakes.

Looks like the post for center pull brakes is mounted higher up on the frame/fork then what the post for roller cam/U-brake's are.

Shimano U-brakes and SunTour Rollercams take the same bosses. I'll hold some Weinmann 999 750s up against my mountain bike to see if it would be feasible to use them, although the current RollerCam front / under chainstay U-brake system works so well I do not want to mess with it.

MAFAC made special posts for the purpose. I've seen them on Ebay, both with and without the brake set.

I did a bit of Googling after my post this morning, and found that you can still buy Dia Compe posts and the hardware to convert their other brakes, like the little springs and the D-plate that the spring end mounts into. I remember that another member here had actually rounded his D-plate into an O-plate, so it's nice that these are still available. Those sets should also work with the Mafac brakes, too, using the original Mafac springs.

Not exactly centerpull and no protruding post but in another instance of what it old is new again, the latest trend in breaking for high-end road bikes utilizes dual pivot calipers in which each of the caliper pivots are directly bolted to the frame/fork instead of being mounted via a central bolt.

I did a little research...this looks like I was correct:

That Velosolex appears to have brakes still bolted to a backing plate that spans the stays...

I do remember seeing some high-end Peugeots with gold-in-appearance MAFAC brakes bolted to frame-mounted pivots. I'm surprised I lost the link, because I love stuff like that.

I hate to be 'That Girl' but the fork looks funny.

Thanks, this preliminary survey confirms my suspicion. Better get a torch and some brass then :)

You are correct Sir! On page 113 of "The Custom Bicycle" there is a picture of a frameset from Peueots' custom shop. So I suppose it wasn't a mass produced fame?

The 1982 Trek 720 had the marvelously cool Gran Compe centerpulls

This thread, and that photo in particular, has me thinking, which is not always a good thing.

How do brazed-on centerpull brakes compare with other types in terms of braking performance, tire clearance, fender clearance, etc? My old Trek 720, a 1982 bought as a bare frame, has never had good enough brakes for its intended purpose (touring). And it needs paint anyway. I've been waffling for years about having cantilever bosses added. Are centerpull bosses worth considering as an alternative?

No worries! Marlo Thomas FTW :thumb:

This set-up is reputedly the best in town when it comes to power and modulation. Jan Heine thinks so, the Dutch guru of these matters too, so that's why I started this thread. Clearance is good to, I compared my MAFAC competitions to several canti's, and the limiting factor for fenders is usually the frame itself. Maybe 50 mm tires plus fenders will get you jn trouble, but that's well outside touring tire range anyway.

Speaking of Jan Heine, he is in the process if producing a (better) copy of the MAFAC Raid. Read all about it here.

The top PY10's had them in the mid 70ies. Semi-custom built frame from Peugeot's special division, a replica of the bike Thevenet won the tour on.
