    Are Road and MTB 10speed interchangeable?

    Quick question guy,
    It may have been ask before but couldn't find on the search function

    Will the 10 speed Ultegra shifter work with the new 2x10 MTB derailleurs?
    I am asking because I am considering this on my touring bike setup

    Yes it will. Drive components are usually gear set specific. So if you have Ultegra (8spd) shifter you could use it with XT, Decore, SLX, XTR, (8spd) specific cassette, derailleur, cranks etc...

    Did you not understand me, I said "drive components are usually gear set specific', so...

    5spd Ultegra interchanges with 5spd Decore, XT, LX, XT, XTR, etc...
    6spd Ultegra interchanges with 6spd Decore, XT, LX, XT, XTR, etc...
    7spd Ultegra interchanges with 7spd Decore, XT, LX, XT, XTR, etc...
    8spd Ultegra interchanges with 8spd Decore, XT, LX, XT, XTR, etc...
    9spd Ultegra interchanges with 9spd Decore, XT, LX, XT, XTR, etc...
    10spd Ultegra intechanges with 10spd Decore, XT, LX, XT, XTR, etc...

    Actually, I think Bullit is correct to be concerned and ask twice. I believe Shimano came up with new cable-pull ratios for their 10-speed mountain-bike gear. For what Bullit is doing, I'd want to hear from someone who has been there and done it.

    The "shifting ratio" on Shimano 10 speed MTB components are no different than Shimano's 10 speed Road components. The only difference that exist between those (2) component groups -> (Shimano 10 spd MTB and Shimano 10 spd Road) exists in the jockey wheel assemble on the (rear derailleur). And that (1) difference only restricts what cassette gear range one can use with each of those derailleur(s). For example Shimano MTB rear derailleur(s) can handle all 10 speed cassettes that Shimano makes, but the Shimano Road specific rear derailleur(s) can only handle a cassettes that have no more than 28t. And that wasn't the case in Shimano's 7, 8, 9 component groups.

    @fataqui, read the first couple or three messages in this thread:

    2011 10 Speed mtn and road STI

    Actually, the #2 post seems to sum it up nicely:

    2011 10 Speed mtn and road STI

    Hi


    I know what works for me and that isn't case. I have a pinarello rokh that I use strictly for my road touring bike, (no off-road touring), and my shifters on that bike are shimano ultegra 6700 10spd, crank shimano ultegra 6700 compact gearing, and my rear derailleur is a shimano rd-m980 sgs with a shimano cs-m980 cassette 11-34. I use all XTR for my rear components on all my touring bikes because they offer me the kind of security that none of the shimano road components have. I mean... I have never had a single rear XTR component ever fail me, whereas I have had many shimano rear road components fail me miserable.

    Shimano tells us otherwise...so what does the setup process look like?. I'd love to have some ultegra STIs with an m980rd all 10sp for a drop bar touring mtb. Sounds Mcgivery, which is OK if it is proven with sound methodology. If not, I'll pass on the snake oil.

    Only 9 speed and less Shimano road/mtb shifters can be cross compatible. The issue is the cable pull being different. Shimano decided to either deny us of that or it was an engineering side effect for 10 and 11 speed systems. If you did a hack to allow otherwise, we'd LOVE to hear it!!!

    Loud and clear.
    5 out of 6 isn't bad. Just the 10 speed stuff isn't interchangeable. If it has been mcgivered to work, let's see evidence! Shimano themselves say otherwise.

    Shimano has never made a "Decore" group, and most of the others you list have never had 5-, 6-, or 7- speed versions.

    Any of the road and mtb 10-sp shifters and derailleurs are NOT interchangeable. I would also like to see how you are doing it.

    The trouble with common sense is it is no longer common
