I'm willing to bet that the correct seatpost size is actually 26.8 mm, not 27.0. My 1977 Pro Tour is 26.8, and others here have noted the same on other bikes with Tange #2 from this era.

actually it is 27.0. i brought home both 27.0 and 27.2 seatposts, and the 27.0 slides in easily.

Neal, how do those long-reach center-pull brakes work?

I'm not talking about the materials, rather the geometry. It rides like a full tourer. IMHO that's boring as all hell if you aren't actually on a fully loaded tour. My Pro-Tour was the Belle of the ball but rode like a heifer. I don't do full loaded touring so I dumped it...NFC and all that.

following up on this one - I stripped all the paint off this weekend and the bike looks uhhh-MAYZING!
One thing I learned is that Kleanstrip Aircraft stripper (in an aerosol can) is weaksauce. It did not work well, only removed paint in some areas. The next day I bought Rock Miracle liquid/gel stripper and that stuff worked great. Literally started melting the paint off as soon as I brushed it on.
the build is mostly done now, just waiting on some tires for the final assembly. I'm looking forward to posting pics soon. This is one of the nicest looking bikes I've ever built, which says a lot.

...and a follow-up question:
I'm running a set of 650B wheels from an old Schwinn mtb, Suzue hubs to Araya rims. The rear hub is spaced to 126mm, matching the Centurion's spacing. Derailleurs are Suntour Cyclone GT.
So, can I run a 7, or even an 8-speed screw-on freewheel? Or does the rear spacing limit me to a smaller number of cogs?

Agreed. 7? If not now, then with a slight redish. 8? No, not with your current hub.

Major progress made:
i think the rack is a keeper, not sure about the bars. i've always wanted to try upright bars of this style but i confess that i don't dig the look. pretty sure about the stem shifters... they actually look kind of cool and i want to see how they are ergonomically.

That looks really nice, you weren't kidding. That is one beastly rear rack. Who makes that one?

I kinda agree on the bars, they look massive on this small frame. But that doesn't mean that upright bars can't look elegant on this bike. You just need something smaller, like the Nitto Dove, or maybe the VO porteur or Postino bars.
Fenders need some tweaking as well, decrease the radius, and also rotate the rear one a couple of inches forward, so you have a couple of inches of fender passing through the chain stays. That's how those extra long fenders were meant to be installed.
What's holding the rear rack to the seat stays?

I saw your response and wondered which doofus walked right into that one. Oh my God, I'm the doofus.

Looks good, man. I believe I can hear it calling out for gum walls.

Man, that thing is the tits. The stem shifters look very appropriate for the build too
