The melvin has floating pulleys that can move with your chainline.

Yeah, I like that one. If my 52 tooth big wheel "drop bar" conversion does not work I may convert to a three speed like that bike. Why 52 teeth, well, I am still pretty strong and the Kansas wind can get behind and push me along at ridiculous speeds. I had, and it is not terribly unusual, to have a 30 plus MPH tail wind. I bet people did not know old MTBs could do 40 MPH! Well, not sure, but my new GT (roadie) nearly melted its tires I was being pushed so fast. Yeah, I call my wife to come get me, when it blows like that, I go one way and cheat on the return. My point is, a big gear range might be needed for me for my conversions mission profile. I am using an Origin 8 Tikki mustache type bar. It has a nine speed cluster. Probably going to use Tektro levers and a Shimano 9 speed bar end with Velo Orange thumb converters.

A 52X13 on a 26 inch MTB cannot be too much higher than a 48/11 on a 700C, I guess, not bothered to calculate it, suppose I should.

Where can chainrings be (reliably) ordered for older Shimano cranksets?
