I see that partial mark now. I haven’t seen a taller vintage stem like this except in a 60mm. I haven’t been looking for long, so maybe they are out there. Of course, the Nitto Technomic is available, but I didn’t really want something that new on this 72 Fuji project. I have somehow come into 3 of the 60mm extension versions of this stem but wasn’t having luck with an 80 or 100. I will put it on and report back on a ride after the snow melts. It actually doesn’t feel sloppy upon installation, and snugs up just like the ones marked 22.2. As I mentioned the difference is .008” and we aren’t talking a precision application like bearing tracks or such. The seller did misrepresent it, but it suits my needs and it would be a pain to return.
