Any any seat post ending in a odd number is rare. Seat posts are normally manufactured in even numbered, 0.2mm increments. A difference of 0.1mm from the 26.8mm standard is not significant, as the binder slot would only have to cinched an extra 0.3mm. I can only speculate on the reason for these odd sized posts, but I doubt the seat tube's top butt is 0.05mm thicker than the standard. More likely, the post was manufactured slightly undersize and rather than rework them the manufacturer stamped the true size, knowing than the difference would not affect fit or function. Knowing the Japanese approach to quality, I suspect they probably even notified Miyata and received approval before shipping the posts.
