Do many or y'all use a 4th hand tool to set up the Weinmanns? I've been having trouble getting the rear caliper on my bike tight enough, lately. Maybe some more of that coordination that is disappearing with birthdays.

Here's your basic Schwinn Approved/DiaComp on my Twinn Sport. This is the bike I've equipped with quad brakes, two centerpulls and two drum brakes.

Dan, not quite, but it stops significantly better than it did with the original front side pull and rear drum alone. The combined rider weight is about 400lbs and the bike about 50lbs. Add that to some of the hills I have and you can see why the need for some major breaking. One of my co-workers rides a really nice modern tandem with her husband. Their weight is about the same but the bike is lighter. They run two modern disk brakes and they stop on a dime and collect change! |

Opinions?
Working on a 1970ish Falcon Black Diamond.
I have a set of Altenburger Centerpulls that came on the bike, but I came across a cool looking pair of Mafac "Racer" Centerpulls. The Mafac brakes are on a vintage peugeot bike at a thrift store. They want $40 for the bike but if it is still there in Feb it will be half price. Any constructive opinions? My Altenburger brakes. http://i352.photobucket.com/albums/r...e/100_4486.jpg The Mafac "Racer"s http://i352.photobucket.com/albums/r...r/IMAG0699.jpg |
Those Altenbergers don't look good. Are you sure they're Altenbergers? Perhaps the levers are, but the calipers look like crappy Weinmann clones.
Mafac centerpulls are my favorite centerpulls. Once you set them up right, they work very well. Tom |
Ah, I forgot I have some Altenbergers in the fleet (on my wife's bike). Except they're side pulls:
http://farm3.static.flickr.com/2796/...b202a2077b.jpg Can someone explain the difference between Altenberger and Weinmann? Were they different companies altogether or was it just a branding difference? |
Good question, southpawboston, and I don't know the answer. Those do look to be made by Weinmann. Aren't those the dual pivot model? I know they made one, long before the term came out.

Tom Neal, thanks for that link. Founded by Karl Altenburger, a professional cyclist in the 1930’s, Altenburger was mainly famous for manufacturing aluminium rims and brakes. By the time I came to experience Altenburger products (the 1970’s) they were irritating items that promised much - but just failed to deliver. In particular their brakes were extremely similar to those of Weinmann (a famous Swiss company) but slightly less accurately made and missing the tiny feature that was the key to painless adjustment. When UK manufacturers ran out of Weinmann they would often fit Altenburger as a temporary stop gap - and bicycle mechanics all over the country would groan. Maybe things were better in the 1950’s. Altenburger’s most distinctive product was the Synchron brake which foreshadowed the Shimano dual-pivot design. |
And here are the Weinmann Symetric brakes on my Super Tourer, which kind of look like Altenburgers!

Frogbutter, not only did you score minty fresh calipers, those are excellent, excellent levers. I have a lot of data of how brake levers survive crashes. Mafacs are some TOUGH levers.

Did you grab those right away cause I didn't see those and I there right when they opened? I was looking for a Mafac cable hanger and a spare caliper for parts but would of grabbed those if I saw those. Here are my racers on my 73 Raleigh Comp. I not finished with front as it needs a matching bolt for one of the arms and it has a Shimano cable hanger instead of the original now lost Mafac one. They do have Koolstop pads now over the crusty 30-40 year old pads.

These are set up wrong with pads that were not "thick" enough, but it is a pic.!

noglider, I am really looking forward to getting this bike project going. The brakes and levers are like icing. |

finding correct straddle wires for Mafac Racers can be a pain, i've found

http://budgetbicyclectr.com/media/ca.../i/file_14.jpg Perhaps a cable knarp would work instead, but I haven't tried it. Neal |
I just rebuilt my Racers and uses derailleur cables. I had to very slightly sand the cable head for it to fit in the bobbin. Just a few seconds on a bench grinder. Nothing a piece of sand paper couldn't do in less then a minute.

CLB2 brakes to be installed on my Mondia... Note the angled brake arm pivots, and especially that the brake spring **IS** the straddle wire. An interesting design...

The problem I've had with Mafac levers is that the basic models (non-drilled, half hoods) seem to rattle like mad. Or maybe the ones I had just got deformed somehow over the years.
