I saw on another forum someone fitted 33m Challenge GRavel Grinders (which eventually measured 36mm wide), and those barely fitted with few mm to spare on new Endurace Disc. The front has bit more clearance than the back.
I'd also be interested if a 2" 650B tire/wheel combo would fit as that should roughly equal same overall diameter on 33m / 700C tire.
