rear brake conversion bracket

[5speed]

is there a conversion bracket to change a schwinn single speed ballooner or midleweight frame to install a caliper brake when u have a non coaster 3 speed hub?

Yes. There's one that bolts on, made by Weinmann.

They are hard to find. I made my own adapter, although not as good looking as the Weinmann, it worked. I used two plates cut to match the frame and it just bolts on and can be adjusted.

That's a neat little gadget! I was going to suggest using clamp-on cantilever bosses.

They are challenging to come across. Took me about 6 month to find one at a price I was willing to pay. They were offered to me in the $40-$75 range.

Super Hard to find though....

I need those as calipers don't give me enough braking power. I've only found the bolt on kind for the tubular forks like your pic shows. I'm still looking.

I've got an idea that a U-brake, mounted near the chain stays, might deliver the most elegant solution--low...almost hidden. There's an original Odyssey PITBULL here, just waiting for the 'right' project.

I would concentrate on setting up a functional the front brake. When you really need to stop, that's the one that does the work.

Here's a thought: modify a rear reflector bracket to mount the rear caliper brake. Cut it off with a hacksaw, round off the edges with a file, and drill it for the brake bolt. Here are some candidates for the procedure.

Bicycledesigner.com sells them but they were out of stock on my last visit.

That Weinmann gizmo is pretty cool. Never saw one of them before.

I gotta wonder if something like that Weinmann adapter couldn't be fashioned by grinding a relief across one of these bad boys, drilling a mounting hole, and adding a stud for the caliper assembly. The cost of this fitting less than two bucks at Home Depot.

Was thinking of same yesterday. I'm almost sure it should work.

There are a variety of bolt on center pull brakes available. I have several sets. Cost is high but you can find deals.

 

[RustySprockets]

Sorta what I had in mind...you get the idea.

Some older Huffy mountain bikes had a plate that bolted onto the rear triangle that they used to mount cantilever brakes onto frames without braze-ons. I've scavenged them in the past for klunker projects.
