That said, when I was kind of new to FD adjusting, I would chase adjustments around and get frustrated. Then I learned that it works really well to completely disconnect the derailleur from the cable and completely re-adjust it starting from step one in the manufacturer's guidelines: alignment, height, limit screws, cable attachment and tension. Everything, not skipping any step. You won't overlook anything and might get some insights that help you do minor tweaks in the future.

4 proper cable tension.

Large/large and small/small with rub is normal, as stated above. It can vary. I have more rub on older drive trains then newer ones. The Campy Record 10V on the De Rosa is nearly imperceptible but it has a plastic insert on the outside of the cage.

The 2x7 Nuovo Record on the Colnago is very noisy in x-chain configuration.

Can't say for sure, but I think the flexibility of a narrow chain along with chain stay length are major contributors along with cage width..

Now when a triple is in consideration, the FD is often a different design. The Campy FD example in the following pic has a "step" on the inside plate near the bottom. Hard to see in the pic but it is there.

I know there isn't clearance for the ring in this picture. This condition is what alerted me to realize I had a triple FD instead of a double. It ended up on the Pinarello. Another way you can id the difference is to look at the "arm" with Record stenciled on it Note the location of the "D" relative to the limit screw.

For example, Shimano documentation indicates that the 3 or 4 physically smallest cog of an 11 speed cassette cannot be used with the small chain ring without rubbing.



It sounds like your FD is not properly adjusted. What is the specific model of your FD? In my case, Shimano FD-5800, I got better results from following the steps in the Shimano dealer manual rather than the Park Tool video.



The chain will always be noisier at an angle than when perfectly straight. If you mount the bike on a work stand and pedal and shift, do you see or hear any actual rubbing between the chain and the FD cage, or is it just noisy? Also, have you checked whether the chain is worn?
