I’d prob go with 30.9mm if it rides well. I certainly wouldn’t sacrifice ride quality for people who want a dropper post.
the ability to have SS and gears on the same frame would suit more people.
44mm headtube.
Then nice colour scheme and metal headbadge and your sorted.
Not arsed where its made as long as they know what they are doing, (i’m not a welder racist)
I think £500-£600 is a fair price for all of the above.
