Just got new bike back from LBS after they ordered a bar/stem. I had HED Alps wheels on the bike when I took it in that I wanted tensioned/trued. When I got it home, I noticed the saddle wasn't centered, seatpost was higher than where I had it marked, and that the wheels hadn't been trued.
So I threw it up on the stand and corrected the saddle/seatpost, and changed out the wheels to the Dura Ace 7850's (pre tubeless) it came with, which are new. When I was done, I noticed a small bearing on the floor. I know the DA hub doesn't use cartridge bearings, not sure about the HED's. It's possible the bearing is from something else, but I have no idea what it would be. I just don't see any way the DA hubs, when assembled, could drop a bearing. When I called the LBS, they didn't see any way that it could lose a bearing either (although they thought the DA hub probably had cartridge bearings). The asked me to check hub play in the DAs, and there is none. They thought that it is possible that a free bearing in the shop might have stuck to something, which I guess could happen.
Long story short, should I be concerned enough to take the wheels in, hubs disassembled, and check to make sure all the bearings are there? I have never had them Or am I OK as long as there is no hub play? Again, this is a new bike (bought elsewhere than LBS as they aren't a dealer, but I have a great relationship with them...in fact, they told be not to pass up the deal on this bike). I can't think of any other component that would have loose bearings on the bike. If it helps, the group is DA, the headset is FSA (whatever BMC uses with their frames).
Thanks in advance.
