I bought a Co-Motion Roadster end of July. It had just right at 100 miles on it and it sat in the owners house for about a year. We now have right at 790 miles on it. It has always had issues with derailer adjustment. The previous owner complained about it. It has always made noise when in the 54 12-13-14 configuration with more noise in the 54-12. It has FSA 54-42-30 chain rings with ultegra components. I took it to the LBS where the bike was originally set up and sold, twice. After the last trip, I had some trouble getting into the 30 chain ring. I have adjusted the front d so that the chain only rubs just a little. The big noises come when we are in the 54-12 and really pushing on the cranks. Then it is very noisy. I took it back to the LBS today. There is a new mechanic there who seems a lot more experienced and he is going to go through the whole thing again. We did find a couple of chipped teeth on the 54. He did some adjustments on the derailer and it only makes noise when putting pressure on the right crank.
Have any of you had a similar problem or have any idea what it may be? My first thought is that it was set up incorrectly in the first place and if so the LBS should eat the cost of making this right.
