pic attached from phone, will edit in a bit asking info. I havenít started a search yet, Velobade or else where.

One brake is is missing the step down ferrule and adjuster, prominently shown on good one. NOS.

I remember we got a sample of these from Weinmann at Trek BITD. Don't remember what happened to them. Probably sat on a shelf for years until somebody binned them. Too bad; they're probably worth something now.

Good ol Velobase.com

late '80s, Delta Pro. Mine take recessed bolts.

VeloBase even had a closeup of the missing piece(s). Without an adjuster, I'm hoping to make this work (edit: meaning an acceptable cable stop)

Questions would be to anyone with knowledge of, experience with, or 2nd hand rumors about their performance.
Not lightweight. Short reach.

Assuming a fix for the one brake, this might be a component that deserves a bike built around it.

I don't own any late 80s or early 90s framesets?

Anybody got one for parts????


edit: I'll even take solicitations for an appropriate frameset for black Deltas from Weinmann.
Does it have to be Swiss? The Mondia is 1978 and too nice to change. Condors don't come around every day.

I've seen that "Semi-auto" quick release cable stop assembly for sale on their own, usually NOS and not for crazy money. Just do searches in Ebay. IIRC, it was shared with a couple of other brake caliper models at that time.

Credits to you ++++++++++++++.

Found on the-bay, for a fair price I guess. Sold.


Now,.... what (yet to be purchased) frameset fits them best?
Wondering if they were ever original equipment on a retail bike?

Very glad to have helped!
I'd feel really bad too if my Weinmann Deltas were missing a part!

Early Swiss "STEAM PUNK"...

I've never seen those brakes in person or even a picture of them on a bike.

Beauty is in the eye of the beholder and everyone has different aesthetic tastes. For me, they look like economy model techno geek knock offs of Campy Delta brakes.

I have 3 different sets of Campy Deltas... Not impressed by their performance - just like most pros in the peloton when Valentino lost his way.

Weinmann appears to have been trying to make themselves relevant in the market place when those brakes were introduced.

E.G. they sold some Weinmann badged or maybe licensed MAFAC cantilever brakes to try to get a piece of the MTB, Cyclocross and Touring action.


Later they came out with some more modern looking arms.



Nothing against Weinmann brakes. I have 3 different versions of Carrera brakes that I use. Recently I got and early 70's Raleigh Competition with Weinmann center pulls. They stop surprisingly well with good brake pads.

Aesthetics:

This?



or this?

I have both Campy and Weinmann Deltas on two of my bikes.....
Actually, the Weinmanns were so much easier to set up and make work properly than the Campy.
Sure, Campy put more into the styling of their Deltas, as pretty much expected when compared to most other marques, but it seems like Campy just went overboard trying to improve their Delta brakes that they ended up making them unnecessarily complicated without too much improvement on their braking performance as they went though different generations of the brakeset.
Also notice in the pics how Weinmann was able to make their Deltas much more compact (maybe more aerodynamic with less frontal area?) than the Campy. A much more efficient brake package IMO. Braking performance-wise, I would say they feel pretty much the same. with both easy to improve with better compound, modern brake pads.
Delta Brake are just "different" you either like the way they look or you don't..... Heck!, I don't like the way bicycles and most things on them after the mid 90's, but I don't care cause I'm sure I'll never have to own nor ride one of them!.....

Keep in mind that these came out at a time when purported aerodynamics trumped weight.

Aerodynamic brakes could have weights competitive with traditional, high end, side pull calipers. Shimano's Dura-Ace AX was actually slightly lighter than their Dura-Ace EX of the same period. It's interesting to note that Campagnolo, Modolo and Weinmann were introducing their delta brakesets, just as Shimano was discontinuing their delta design. Shimano's Parapull design remains my favourite of all the 1980s delta brake designs.

The Boulevard of Progress has many side streets to visit and enjoy.
A few grams too heavy for some - I don't ride with a bell or fat tires.

Definitely a different aesthetic - which is a draw.
Perfect for the right frameset I need to find. Maybe the black Harding/Holdsworth, already in the fleet.
I like them a LOT on @Chombi1 's Alan.

Here's the Campy Delta on my Montello:

Wasn't sure about it till I mounted it in place of the Chorus calipers that was on it.
I think it looks great on the bike.... You can't really tell how it looks like on a bike until you do so and see it in the flesh.
