It's called a pinch bolt, its washer may be important too. Some have a "tang" that's needed for correct indexing. It's hard to tell from the photo.

My "new" compact double has 50/34 with a 11/32 cassette and shifts well and reliably even with Sora components. I'm happy enough with steep loaded climbing and fast road descents. I'd be okay with a...

Also check that the dropouts are parallel to each other, and perpendicular to the axle. You should probably use a dropout alignment tool for accuracy.

The catalog I see shows that bike has a mechanic disk brake. Usually the brake cable housing is attached to the fork with a cable tie or similar. Perhaps that broke during transport.
