I have a XT Dyna-Sys 3x10 (42/32/24 - 11/36 casette.) that I'd like to convert to 2x10.

40 & 26 looks like the optimum gearing for my needs but I'd like some user input on which rings to buy, FRM, Blackspire other OEM etc.

    I reckon that'll be fine! TA Chinook rings get my vote.

    I'd recommend going 26/38 given your cassette spread, but that doesn't take into account the terrain you ride. I run 2x9 on Middleburn Hardcoat Slickshift rings, longevity and shifting is great. Totally recommended!

    Deore XT, it's a XT 10 speed groupset Nick.
    FRM supply 40-26 in a conversion kit, do you think that's too much of a jump ?

    TA Chinook list their rings as "compatible with 8/9 Speed" I assume they can be used with 10 speed ?

    Yep they'll be fine.

    Doubles are often 14t jumps, 28/42, 22/36 etc, so the mech shouldn't be a problem. I've never had problems with a similar jump.

    Are you guys sure that a standard 10 spd triple front mech will have the ability to shift that many teeth?

    For example an SLX Double and bash comes with a 22 36 , but I was under the impression that you need to use either a SLX double or Saint double front mech with that particular chainset.

    The reason I am asking is I was considering doing the same with 24 - 38 rings but was concerned about compatibility issues with my existing XT (triple dynasys) front mech.

    Your saying it should be fine and I wouldn't necessarily need to fit a 10 speed ring, a 9 speed would do the job?

    which? there is more than one. 2 ring? 3 ring? band mount? E or direct mount?

    Sorry Nick, it's a triple, band mount.
