Well thanks to all you smart people, I went to check if it was squished and it was! Didn't even think about that. So it is a 26.6 so I put one on.
Thanks again!!
Thanks again!!

Seatpost
Seatpost is either 26.6 or 26.8
Forget which one. I have 1990 expert and master, both same frame.

Yes, 26.6 or 26.8mm sounds correct. Unlike most manufacturers, Tange favoured a double butted seat tube. Most of their butted tubesets standardized on a 0.9mm top butt for the seat tube. This resulted in a 26.8mm inner diameter. Allowing for 0.2mm clearance resulted in a 26.6mm post or 26.8mm if the manufacturer performed a reaming operation.
While the top butt resulted in a marginally heavier frame, it had economical and logistical ramifications for bicycle manufacturers, who could use a common size post across a wide range of frames.

Looking good, BTW, @2cam16. Can't wait to see more of it.

Just added hoods to mine today. Long process for such a small addition- unwrap bars halfway, disconnect brake cables, remove cables and housing from levers, add hoods, hook cables and housing back up, rewrap bars, and cap cables.
But i needed to add the hoods because I just listed the bike for sale on CL. I love the feel, its just too cramped. Itd be awesome if the bike had been made in 1 size larger.
The 105 components, even at over a quarter century old, are crisp and smooth.
The frame is stiff and strong.

No harm trying.

So- rookie question- who built these? I guess that's a question in a larger sense about Diamondback and Centurion, but specifically these TG welded series- who in Japan made 'em? Or does it matter what factory since we know the Tange tubing was quality & they were well-equipped?
I'm thinking of picking up a Master TG just like this one myself. Enjoying the view of your build process!

Ahh, good to know. The hoods do look quite nice. Hope you can locate the missing plastic bits.

So no expert here, but most frames from quality companies were built in the same factories at this time in Japan. Almost all of them are very good quality for production frames, especially when good tubing was used. The Japanese really had it down by this time and most of those frames are still in use today from most of the companies we know and love, Schwinn, Diamond Back, Centurion, Bridgestone, Specialized, Miyata, Univega, Bianchi and the list goes on and on and on. Spacialized had a big hand in this as they sent two of the best in the business in Merz and DiNucci there to get them making quality frames since they had the factories, but didn't understand how to achieve much higher quality in what they were already doing. Once they got it we have 10,000's of well priced quality frames to this day, still do even though production has long since moved to Taiwan where they still make very good quality at pricepoints that are doable and a great value albeit cookie cutter.
