Canyon Cockpit/Fork noise

Hi everyone,

Bike mechanic just replaced cockpit bearings (integrated stem/handlebar on road bike with CP0018 with internal routing). They were rusty.

Now:

– No play/slack: mechanic checked, no lateral movement.

– But turning the bars makes a scraping/grinding noise (video uploaded), especially on slow turns. Doesn't turn super smooth, feels some friction/resistance.

Is this normal for new bearings? Will it bed in after some miles?

Or bad install (not enough grease, overtightened, dirty…)?
