Since my secret is out, I will tell you all the story. Apologies in advance for my lack of German!
First, the brakes are a one-off project that won't be made again, so apologies to all who would like some.
I had been frustrated with my titanium Phoenix because I didn't like the V brakes but also didn't want to put disc brakes on the bike. What I wanted was a cam-brake solution. I proposed a lever-link style brake to Charlie, on a plate that would mount on a custom U-shaped base, similar to the one WTB briefly made for the Judy forks. I noted to Charlie that the modern suspension lowers would likely work better since the lowers were beefier as was the connecting brace. He wasn't convinced until I sent him the diagrams for my Fox F80 fork. He said he would have a look at the fork so I sent it to him.
At the same time I sent the frame to Steve Potts to remove the cantilever bosses and to put on some chainstay rollercam bosses. (my initial plan was to epoxy and rivet on guides and bosses like on my Cunninghams but Steve was concerned that this would cause the frame to crack).
When it is built up, the bike will have the lever-link on the front and a toggle-cam on the rear. The rear will also have a custom Cunningham mud-deflection guard, and under-bottom bracket cable guide. It should be pretty rocking.
Charlie based the arm design on his first toggle brake design. He liked the beefier arms and also wanted to use a U-brake/V-brake style pad, since he hasn't been as happy with the pad hardware on the speedmaster arms.
The first photo shows the tool Charlie used to shape the arms. You can see the initial blanks for the brakes Charlie made for him and I.
All the forming was done by hand.
and
Starting to come together!
Set up for testing prior to sending for anodizing. Charlie really likes the file marks on the brake arms.
Here is another view.
And another.
And another.
And one more.
Now back from anodizing.
