...and I'm curious if anyone has ever thought of it.
Okay, as we all know Suntour kicked butt in the 70's and 80's 'cause they had the "slant parallelogram". That's great, and it was great, since every manufacturer has copied it, nowadays. But, has anyone ever explored this thought, or better yet... done it.
Has anyone ever taken a "claw adapter" for bikes sans derailleur hanger, bent it about 15 degrees outward (or however much a slant parallelogram slants outward), and attached a straight parallelogram RD to it? Here's a picture as an idea of where I think bending would work.

I'm just wonder if this could be a simple way to make a Nuovo Record (or other similar straight parallelogram) rear derailleur work better, if only by copying the slant principle. I'd do this, but I lack both the claw and a NR RD. But maybe another member will be intrigued about this and do it.
Just an idea/conversation starter. If you don't think it'll work, tell me why. I just figure it would be interesting to try, and might actually help NR's shift better.
