That shit just shouldn't make it to the show room floor. Years ago when I worked at a shop during assembly we pulled down and greased relevant bearings as required which were generally headset, hubs and bb (bmx).Just greased my headset, after it started creaking like an old wooden ship.
Typical new factory assembled bike - not even enough grease in there to cover your foreskin.
I was disgusted that my wifes $3500 mtb had a ball bearing no grease headset. FFS it wasnt even floor stock it was a special order straight sale and the extra 1% wasn't given. I fixed it but given the amount of checking and tensioning I did when we got it I would rather have gotten it in the box.
