    Will I have a problem running an XTR (or any Shimano) rear der. with my Ultegra equipped road bike?

    Why would I do this? 95% of the time, I don't need the extra range that a road triple would offer.
    For the other 5% of the time, I figure a MTB rear der would let me run cassettes with greater than
    27t and give me the range of a triple without the added weight and sometimes painful shifting of a
    road triple. I know I might need to run a longer chain, but I'd be o.k. with this for the rarity of
    tackling big hills.

    Any input on problems I would run into or other issues to consider?

    Thanks.

    I'd just run a long-cage Ultegra derailleur ( RD 6500 GS ). Shifting performance would be better as
    the der is designed to work with the STI levers.

    Oops, I see your post stated "larger than 27t" - after looking, I see that the max is 27t for the
    long cage ultegra. My bad.

    No, all Shimano rear derailers index the same since 1997.

    I haven't read the whole thread. If Peter doesn't already have a rear derailer, there's no downside
    to buying an XT.

    If he already has an Ultegra, however, it isn't necessary to replace it just 'cause he wants
    something lower than 27. Any Shimano rear derailer will handle a 30 tooth in back.

    That's a popular setup and works just fine.

    MTB rear ders from shimano are also designed for use with STI(shimano total integration)...

    No, provided it's not over about 5 years old - the cable pull has been the same for some time. I
    have a very cheap Tourney offroad rear derailleur on my bike - quite frankly these days all
    derailleurs are much of a muchness provided they have the capacity.

    No, you shouldn't have a problem. Many tandems, for example, are spec'd that way from the factory.
    Our Santana road tandem has Ultegra 9 speed levers with an XTR rear derailleur and an XT 11-34
    cogset (chainrings are 24-38-48 with an Ultegra FD).
