Greetings Wyatt I will echo comments above. With DiaCompe 750s I easily fit 584x42s on my green Ramb. The chainstays are the biggest limitation: there was 3 mm clearance on each side. My wheels were true and over 3 years I had no problems, although it was a source of worry.
All of this said, I will share my experience with the conversion. Going to 650 B on the Ramb, for me led to a series of compromises, like shortening my cranks. Using long centerpulls was a hassle: they are less efficient and due to my own limited skills, they are hard to adjust. My beloved Mark’s rack did not play well with the centerpull cable. I took off the rack but then lost capability to use my Shopsack..... This summer I drove back to Seattle from Brooklyn with my beloved lab Princess Buttercup. We drove through Canada to stop by Lakes Huron and Superior. From the first day she ran in, fetched balls, dove for rocks and it seemed she would swim to Wisconsin. It reminded me of what Mother Superior said to fraulein Maria about doing what you were born to do. A few weeks ago I slapped the 700c wheels back on the Ramb along with the Silver brakes, the Mark’s rack, basket, and Shopsack. In the absence of Ruffy Tuffys, I put on Vitoria Corsa Courses. There’s gobs of tire room and the Ramb just sings again in a way it didn’t do with the supposedly cushier 650Bs. It is such a joy. I am sure that wide tires are great. At this point I would only do them on a bike really designed for them. Just my 2 cents. Good luck figuring things out.
