    Centaur Rear Derailleur, 2006

    I have an 06 Centaur rear derail with 09 Carbon 10 Centaur shifters, works great.
    However, is there any noticeable improvement in shifting if I upgrade to a newer Chorus or Record Rear Derail, not counting the few grams of weight?

    If your shifting w/ the current derailleur mated to the 09 Centaur shifters is good, I would't change a thing if I were you. Conisder yourself fortunate, as there have been some out there (myself included) that have been having an absolute nightmare w/ those shifters on pre-09 rear derailleurs.

    They only issue you may have is the rear derailleur tension spring (I've posted pics elsewhere showing the difference, the same as the ones below). The one that has a fuller circle "?" shape inside the paralellogram lacks adequate tension, while the "1/2" circle one is the correct one; but IIRC that was related to Escape Mechanism (completely different topic), which wasn't out until after 2006....In other words: not a problem you should have to worry about.

    You'll not notice any difference.

    That is what I was looking for, thanks to both.

    But would I feel those 20-30 grams, haha.
