    Ultegra 6500 vs. Ultegra 6600 RD

    Shifting with 9-speed STI units, is there any reason not to use the 6500 Ultegra FD, as opposed to the 6600? Ad for 6500 says "The FD-6500 Ultegra front derailleur features an extra wide cage to increase strength and extends service life. Indexed for light-action SIS shifting. 9 speed compatible."

    Thanks.

    FD or RD?

    RD, doesn't really matter

    FD, it's best if you stick to the same speed the chain is, since a 9sp chain is more likely to rub on a 10sp FD, and a 10sp chain will have sloppier shifting on a 9sp FD.

    mind you, you can totally get away with mixing 9sp and 10sp FD/chain without a huge issue.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    For all intents & purpose, I can't find any real difference between the RD 6500 and RD 6600 rear-derailleurs. I've had both and they shift like a dream.

    Here's the bargain to end-all bargains. An RD 6500 for under $40 - brand-new:

    Opps... Very Sorry... it is FD I am talking about. 6500 vs. 6600 front derailler. Am using 9-speed chain, brifters, etc.

    it's best if you use a 9sp FD, 105 5500, ultegra 6500 or tiagra 4500, but it's not a big issue if you don't.

    Are you talking about a front derailleur with a double crankset?
    The 9-speed FD should work better with a 9-speed chain.
    If triple you'll need the 6503.

    The FD 6503 can only be used on frames that run the cables underneath the bottom-bracket shell. It's a bottom-pull derailleur. If you have a Hybrid or a Mtn-Bike, you'll need something other than an Ultegra FD. One that is either top-pull of dual-pull.

    I ran a 6600 with my 9 speed before going full 10 speed. With trim I wouldn't get any chain rub until the extreme crosses.

    If you can get a 6500 you may as well, I got the 6600 because I was having trouble sourcing a 6500 and I knew I was going to be going full 10 in a few months.

    I mix front derailleurs of all types. It doesn't seem to matter much. If it shifts and doesn't rub you're golden.
