A couple of things:
1. Whether it is the right or wrong upper raceway, the frame is supposed to be 30.0mm, and so should the raceway. The only other headset sizes go
up, which is why I was curious as to the headtube bore.
2. It's been a while since I tinkered with that particular headset, but I do recognize the completed headset as being a proper Raleigh / Carlton headset for a Grand Sport.
3. I think everyone is expecting
this headset raceway instead, which is the one associated with the thicker, flatter Raleigh headsets used on the Sports and many other models.
It's obviously a better design for holding loose bearing balls, but I can't say whether it's supposed to be the raceway included with your headset. But it was irrelevant for the question at hand: Regardless of the cup, either shouldn't be smaller than 30mm in diameter, indicating that the frame needed scrutiny.
Since the shop has since assembled it, we won't know. Curious to hear how the Teflon holds up.
