I'm keen on the Genesis and just wanted to see how versatile it would be. I would intend a spare rear wheel for it with a 3 speed hub gear, I can do that whatever the dropout size. But I also considered that I may want to run it as a 1x9 or 1x8 sometime. Have found that you can get chaintugs with derailler hangers incorporated, so it's just the spacing to verify.
I'm quite surprised that rear spacing isn't one of the measurements indicated on the little frame geometry tables.
