    X-Actuation and Exact Actuation

    who is able to explain me the differences between X-Actuation of XX1 tramsmission and the Exact actuation of road Sram parts ?

    i need to know if the S700 hydraulic disc brake set works with a XX1 rear deraillaur.

    yes S700 is 10 speeds. XX1 is 11 speeds


    i already know that it works with a CX1 rear derailleur.

    is the cable movement able to manage a 10 speeds cassette ?

    i need it for a road bike set up 1x10

    It won't work as far as I know. XX1 and X01 are the outliers, any other SRAM derailleur should work as long as it has the capacity for whatever size cassette you intend to use.

    to reply : i installed a X.0 9 speed derailleurs ( so able to manage a 34T cassette only ) with custom gripshift 2x10 , some years ago, with XX 11-36T cassette...

    The heart of the matter is cable pull. Exact Actuation (Road 10 & 11sp, Mtn 10sp) is 3.1mm while X Actuation (Mtn 11sp) is 3.48mm so there is NO cross compatibility. A 10sp X9 or XO RD will work great w/ SRAM 10sp road shifters. SRAM says the max cog is 36, but I run an 11/40 w/ a 50/34 and it's very good, but not excellent.

    Will 11 speed SRAM Force/Rival shifters work with X-7 or X-9 rds?

    If it is 10spd XC rear derailleur then it will work because it is also exact acutation type.

    Next question is your frame set up for road and XC rear derailleurs or just road? You can tell by the angle the cable housing comes out at the back.
