To be more specific, i would like to know if there is an adapter to mount a set of Campagnolo Delta brakes (single mount) to a modern frame that has dual mounting points.

As for the why....its for a carbon road bike (Bianchi Oltre XR4) build im building in my head....always wanted the deltas, could never afford them back in the day.

Terrible Idea. Forget it.

I would be surprised if you find an adapter in the marketplace. The guys I ride with love their direct mounts, strength, modulation, less hardware, etc.

HillRider

+1 There are certainly no commercial adapters and, worse, Campy Delta brakes had a dreadful reputation. They were difficult to setup and performance was mediocre to poor. There are very good reasons why Campy dropped the design relatively quickly.

+2. Might as well just use your foot to stop.

Deltas aren't really brakes, they're Secondary Speed Modulators. Primary is the bottom of your shoe. Back in the day Campy was about going fast, slowing down not so much. I would Ebay those and get some nice brakes that stop your bike.

Aubergine 

Better yet, find a nice early 90s Italian bike and put the Deltas on that.

I'm finding most people who give feed back on deltas are parroting some internet article they read. I'm riding them on my X4. One finger operation in the drops from 40 - 0 is not much if any difference to my modern bike. Two fingers on the hoods is fine too.
Now for your application, I think I might question the practicality.

Need pictures of brake and fork, why wont it bolt up? IDK, working blind.

The Bianchi Oltre XR4 frame is designed to use those new-fangled direct mount, dual pivot calipers:



The Campagnolo Delta caliper uses a single, central mounting bolt:



Thus the need for some sort of adapter. I would concur with the above advice that it is not worth the effort. The Delta calipers were not particularly effective as brakes, just "speed modulators," in any case.

fietsbob

OK, noted ... +1)buy another frame.. that ain't the one


I agree with the C&V option get a frame from the right era for the brakes

Or, all you need is a machine shop ..

Its nothing you will find off the shelf, so it must be custom machined...
need a lot of accurate measuring and dimension ed blueprint/engineering drawings to get any thing not local, to send them a CAD over the web.


[I expect the rear brake is under the chainstay]

Actually, it's not:

fietsbob

thanks .. no one has the Internet coding dosh to overspend like that, here , never expect to see cycle tourists on any,
except maybe the transamerica racers this June, again.

I rode a full C Record group for 18 years and then put it in the parts bin for 8 years looking for a suitable frame. The crazy prices people will pay for C Record with Delta convinced me to just sell it and move on. The groupset is going onto a Colnago Master so the buyer was pretty motivated. However, so long as the brake pads are not worn and the clearance to the rim is small (<2mm) the brakes work as well as anything of that era. As said earlier, a custom machined brace is the only solution.

lear60man

Thank you all. My main question was if there was a commercially available adapter and apparently there is not. Sounds like an appropriate frame from that era might be the best solution.

IIRC, Campag had competition in the "I don't want to stop" department. Around the same time Shimano was hawking their first try at disc brakes that were retrofit to frames.

HillRider

Well, we are "parroting" both internet articles and numerous contemporary magazine articles and books from the day when those Deltas were in production. None of them had anything good to say.

The consensus was that the C-Record version, while very set-up sensitive, did work acceptably but the lower line Deltas were hopeless.

fietsbob

OP seems to only be 'designing it in their mind', may have bought nothing..

lear60man

Well.......I picked up some NOS Campy Record pedals yesterday and put in the order for the frameset this morning. I really wanted a 2000 XL EV2 frame like my old bike (yellow-celeste), but that thing cracked just looking at it. Im still on the hunt for one to repaint and be a wall hanger. I have the paint and decal set in the garage....Most XL EV2 frames were binned due to failures so its a slow hunt.

Once I get the frame Ill take accurate measurements and send them off to my autocad CNC guy. He has done custom parts for my Ferrari's, guns and Studio Scale Millennium Falcon. Ive done some more digging and there are adapters for a modern Campy Delta incarnation from Tririg....Omega X model. With their adapter, their brakes are compatible with direct fit frames. At least now I know its possible if not practical haha.

We all want the perfect bike...warts and all. Sometimes you just say F-it and forge on. It may not be the Uber course weapon, but it will be mine.

When you shop for Deltas, look for the later generation 5 pivot model. Other than the 5 pivots when looking at the innards, these are usually identified by the black rubber bits (versus white). You’ll need a narrow rim, I put new pads on mine and have just a few mm clearance side to side. They are a little extra work to set up but work fine.

Here’s a pic for motivation!

Jeff Wills

^^^ Is that front brake pad installed backwards? I thought the open end should be at the rear... but I'm not 100% familiar with C-Record brakes.

The rear looks correct.

HillRider

I'm not that familiar with them either but I think those brake pads are fixed to their holders and are not replaceable inserts so they can't slide out either way. You unbolt and replace the entire shoe assembly like we used to do.

paulkal

They are not fixed and the inserts are replaceble. Koolstop makes new inserts.
Mounted like this, they will slide out.

mackgoo

Back to the OP.
If you were wanting to do this with a Specialissima I might encourage you to do it.

fietsbob

Modern,.. meaning Carbon Fiber, you can get a frame and fork that take a common brake caliper center bolt ,
other than the one you mentioned..

... and JDT found an example of for an image..
