    10 speed Ultegras on 9 speed bike

    I have a 9 speed Shimano equiped bike. A guy completed a deal with me by giving me like new Ultegra 10 speed STI's. My question will the right hand shifter work on the 9 speed knowing that I don't have that 10 cassette? Second question to change to a ten speed is it a simple matter of just changing cassettes or do I have to change chains and possibly triple crankset. It is FSA Gossamer with outboard bearings.

    It won't index correctly on 9 cogs; but you're correct about only needing the 10 speed cassette and chain now. Your RD will work and so will your crankset, although new 10s chainrings might give you marginally better shifting.

    Not 100% sure what you mean about changing triple crankset. Is that what you have now and the Ultegra STI is only for a double?

    10 speed drivetrains are useless anyway. IMHO. I am even more convinced of this since I read about those two dudes who won a MTB race, 1st and 2nd place, both on singlespeed MTBs.

    Offtopic? You decide.

    If you currently have a triple crank, the Ultegra brifters won't work with it unless they are also specifically triple shifters. 9-speed Ultegta brifters were double/triple compatible. The new 10-speed brifters are specific for one or the other. They may shift ok over the two larger rings but won't access the granny properly.

    My ONLY reason for staying with 9-spd for my new bike was that SRAM powerlinks for 10-spd aren't reusable.

    ...which is why when I got a 10-speed bike, the first thing I did was to buy a Wippermann chain for it. Wippermann 10-speed links are reusable.

    I still run SRAM chains on all my 9-speed and previous bikes.

    Usa a Shiftmate. I just installed Campy Centaur 10 speed brifters with an Utegra 9 speed cassette. It shifts like they were made for each other.

    But I don't fancy spending three times the money for a chain. I like the cheap SRAM chains. PC-951 works just fine, for very little money.

    True, though I've gotten Wippermann 10-speed chains for as little at $25-$28 (on sale, on Tuesday between 12 and 2 PM at Performance, etc.). That way it doesn't cost much more than a SRAM PC-951.

    They're $60 here (10S0 version). The SRAM PC-951 costs less than $20...

    Ouch! I go for the bottom-end one (can't remember the designation, but not stainless). It seems to hold up fine. I'm religious about keeping my stuff in good shape, so it never stays wet long enough to cause problems.

    The 10S0 is the only one available here. The 9-speed version is much cheaper.

    Yep, I did the same thing using 10-speed Record brifters with an Ultegra rd and 9-speed cassette. The performance is wonderful.
