    Yes.But the mech might struggle a bit with the 36.

    Thanks Rorshach, I could go for 11-34 as an alternative.

    Edit: A little more research suggests that it will work with a 36 if it’s a shadow 9 speed.

    On my Boardman Team CX, for CX racing, I use 105 10 speed sti’s, 9 speed deore rear mech and XT 11-34, with a 42T single ring up front.

    Works perfectly.

    Thanks, for the sake of 2 teeth I’ll probably go with a 11-34 then unless someone comes along to say 36 is working fine for them. That does seem to be the conclusion on other forums but other forums are not STW! 🙂

    105 sti,sram 11-32/38 up front and an old xt mech.

    Having had my cx bike all of a day I’m already thinking of going 1×10. My other bikes run 1×9 and a Rohloff so as you can tell I quite like simple gear changing. However I have a question.

    Am I right in thinking that my Tiagra 10 speed shifter will give me 10 speeds if combined with for example a 10 speed 11-36 xt cassette and a 9 speed xt dérailleur?

    Thanks

    Rorschach & cp are you using long or medium cages and does it matter? I know in normal circumstances a medium would be fine for a single ring set up but does the combining of road shifters and a mtb mech/cassette change anything? I can’t see how it would but I’d like to be sure.

    Thanks

    11-36 works fine with my 9 speed XTR rear mech (long cage), 40T up front as well.

    I use a long cage – as I use it with a double as a winter bike as well after the CX season (and it’s what I had lying around!)), but you should be fine with a medium cage.

    A long cage could collect more mud resulting in more mechanicals during a race

    Sorry for being thick but why a 9 speed rear mech with 10 speed everything else?
    Asking as I’m thinking of doing similar.

    It works because the pull ratio of 9 speed Shimano mtb derailleurs is the same as the pull ratio for 10 speed Shimano road levers whereas the pull ratio of Shimano 10 speed mtb is different to either.

    Thanks again all, time to start checking the classifieds for 9 speed mechs, hopefully all the upgrading to 10 speed should mean theres a few about. I’m watching a couple on ebay as well.
