    Hi,

    Bit of a hack job for this one but hoping for success.

    What I’m intending to do is convert my cyclocross bike into a 1 x setup. I’ve got 10 speed 105 shifters and want to use a 9 speed M771 XT rear mech as I believe the cable pull will work. I want to use an 11-46 cassette and want to know if the 9 speed XT mech will clear the 46 tooth with a longer b screw?

    Any help would be great.

    Cheers.

    Tom

    that rear mech will do

    that rear mech will do whatever its told to do by the shifter so no problem using a 9spd mech with 10spd shifters.

    The large rear cog will be the problem as the top pulley wheel could foul the large cog. Most mechs have a tooth capacity, and that mech just doesnt have the capacity. 

    you might be able to get it to work, but it shouldnt 😀
