How can that be the proper angle for a center pull brake? Plus, the angle of the opening set against that interior edge of the donut acts like a razor in stressing and eventually cutting the brake cable... pretty stupid design!
It's such a bad design I wasn't sure what it was there for! And then even once I understood, I never gave it any consideration. The one thing I could have done, and considered doing, was to fabricate a spacer/adapter so that I could have used that bolt-on yoke that I used on the previous frame. But I've already invested too much time trying to get this thing built. At this point, "good enough" is indeed good enough.
