I've got a new bike that's a mix of Ultra and Dura Ace components. I've put around 100 miles on the bike and felt like it wasn't shifting as well and I was getting a lot of chain noise. I had a friend come over and do a tune up. When the bike is in the stand i can still hear the chain noise a little bit, but I took it out this weekend and really heard a lot of noise. It sounds like cross chaining but i'm getting it almost all the gears. After the ride I put in the stand and don't hear it that much. Why would it be worse on the bike?
FWIW. Well, I can't speak to whether-or-not the more recent Dura Ace derailleurs are more finicky to set up, but in the past, they were not ...
I can say that you may indeed need to consider bringing the bike to the shop to resolve the problem ...
However, if you are certain that the persistent noise is being caused by the chain ...
YOU need to better isolate whether it is coming from the front or the rear.
The chain rubbing on the front should be EASY to see ...
Since all other solutions seem to have failed, IF the noise is coming from the rear of the bike, then check to see how the chain passes between the two pulley wheels ...
Because it is possible to snake the chain incorrectly between the two pulley wheels whereby the chain is riding on one of the rear derailleur cage's
control tabs ....
And, THAT will certainly result in an unwanted sound!.
BTW. You can do yourself a favor with regard to expediting troubleshooting if you take the time to look at the Parktool.com website or borrow-or-buy either one of Zinn's books or the Bicycling maintenace book AND also to become as familiar as you can with either one of your older bikes or newer bikes so that you can better isolate the problems as you are encountering them ...
By stripping-and-rebuilding (one of) your old bike(s) you will be able to more quickly isolate & fix problems you may encounter rather than needing to rely on your bike shop or shot-in-the-dark replies from members of this(-or-other) Forum(s).
