    x9 rear derauiller ?

    Is there any significant difference in the 2009 vs 2010 vs 2011 model of the x-9 derauiller? They all have the 1:1 ratio, which I assume means they are zero loss derauillers.

    There are apparently new ones still available of all three year models. If the '11 model does not have any significant improvements, the others are much cheaper and I need one for the Heckler I am putting together.

    All Sram 1:1 derailleurs are plug compatible, meaning any can be used with any 1:1 shifter. The only functional differences are cage width and length.

    Model to model, year to year, the differences are materials, weight and cosmetics. I've always found the best dollar values in top line stuff to be in leftover prior year's models, or the B-level on the current year. In your shoes, I'd save the dough with the older stuff.

    Go new old stock, as they say in the "industry". Save some coin.

    That's what I wanted to hear! I just thought I better find out if the new model had some feature that I could not live without. Since that's not likely the case, I am going for the cheaper version.

    The new ones definitely have one feature the old ones don't. They let folks know that you have both the dough and temperament to always have the latest and greatest.

    Yep, using a 9-speed. Right now I am considering going to a 1X9 since I never use either of the outer rings anyway. I am using 2011 X7 shifters which have the zero loss feature, so they should be fine. I don't ride well enough to need the latest equipment-- I really wish i did, but, at my age, it ain't gonna happen.

    Even the older parts work well enough for any rider.

    If I recall correctly the 09s and 10s are the same. For 2011 Sram changed the placement of the cable holding bolt and switched to vented (rather than solid) jockey wheels. I have a 09 and 11 model and do not notice a difference in performance between the two.
