I had no idea where my 13mm cone wrench was and did not have time to look for it before Christmas. So the co-worker had to take his brand new present to the LBS.
Not to mention the LBS across from the Sports Authority. They fixed up the poor assembly and quick failures all the time.
Are you or any any of the cited mechanics "certified"? That was the question, not could improvements or adjustments be made on a bike if reexamined after purchase (from anywhere), by someone with an ax to grind or profit to be made.
