I just bought a new set of cheap wheels (Alex R500) from a reputable online bike place. They shipped them free and they arrived in great shape. When I unboxed them I noticed that they don't roll very smoothly. Mounted on the bike I noted that when I spin the tire, they stop rolling much sooner than normal (and brake is not rubbing). I am also comparing them to the exact same set of wheels that came with my bike. For the record they are formula hubs with precision ball bearings (I thought they had cartridge bearings, but seller says otherwise). I contacted the seller and they said that they come adjusted from the factory and that after 30 miles or so they should be rolling smooth. I've never bought new wheels before so I don't know if this is normal. Hoping for a second opinion- mount and ride till they loosen up, or adjust on my own. Thanks!
