@anon71759125 have u considered renting a road bike for a day? that’ll answer a ton of questions for you. or maybe find a bike shop that has an alloy bike and test ride it? or even find someone on craigslist that has the bike… test ride it, and if it’s not for you, it’s not for you.
that said… i know it says cinelli on it, but the Cinelli Experience and Experience Speciale could be the ticket. . they all have a threaded BB AFAIK. fits a 28c. Speciale models have a full carbon fork, but i think they’ve stopped producing those. a little over your budget but i really doubt there’s much else out there that fits your criteria.
lets spice it up. i got this surly steamroller. threaded steerer. coaster brake. cross tires. the question - 680mm nitto risey fellas or these 666 crunch bars with unshellacky newbums?
quite a predicament i’m in here, according to my shartpinion.
