• Actually with that Surly 1x10, I notice the frame is for 26" but he's used it as a 29er in the past, and now 650b. Does anyone know how? Does the frame just allow it?

  • I'm running 27.5x2.4" on my 1x1, and 700x42c+mudguards on my Troll (same geo, extra mounts). Frameshave stacks of clearance. 650b wheels feel good and ride well, 700 is fine for committing but a bit less stable.

  • My old 1x1 could take 29×1.8 no bother
