I bought a chain tensioner.

The guy who sold me the frame has been advising me.

I'm honestly not sure. Been sorta carried away with preparing for my wife's classroom and recovering from the cold.

The ID of frame for 1" steerer is 30mm, for a 1-1/8" steerer headtube ID is 34mm.

All the old catalogs are online with specs. Generally the details and stickers change year to year for identification.

For road bikes, 1 1/8" is threadless only.

"Thanks for the photos!
I checked with engineering, and this should be a 34mm inner diameter headtube, designed for an EC34 upper/EC34 lower headset (external cup) and a 1 1/8" threadless straight steerer fork.

To double check this, you can measure that the inner diameter of the head tube is ~34mm, in which case the above specs for the headset and fork will be correct.
