According to https://blackmtncycles.com/tech-info/mcd-frame-tech/:

  • But, really, what’s the biggest tire that will fit, you ask? Honestly, it depends. And I can’t answer that in absolutes. Rim width, variance in tire width… A tire that measures 50mm at its widest spot will fit. I can’t measure every tire make and model, so I am unable to give you an absolute confirmation that the tire you want to run will fit. Figure on a 700c x 50mm or 650b x 50mm.
  • 650b x 50mm? Yes, a 650b or 27.5″ tire with a 50mm width will work and can be a fun tire on this frame.
27.5x2.1 may not work.
