    Mixing 10spd and 9spd chainrings

    So after searching like crazy it seems that using 8/9spd chainrings with 10spd chains is generally fine. But what about using a 9spd chainring together with a 10spd chainring (and all the rest of the drivetrain being 10spd, for that matter)?

    I'm asking because I want to convert my 3x10 24-32-42 SLX crank to a 2x10 24-38-bash and 10spd chainrings seem hard to come by in anything but standard sizes, atleast for less than monstreous amounts of money. I do have a pretty tight budget so if I could get away with using a Shimano 9spd chainring for $20 I'd be chucked.
    If not, could you recommend a decent 10spd chainring for a decent price?

    Also, would it work pairing the 24t to a 38t, or is the gap too big?

    Go for it. I've been running 9 speed Shimano SLX 22/36 crank sprockets and a rear 10 speed Shimano XT (11/36 casette and 10 speed chain) setup on my Carbon Nomad for over a year and it works great. Here in the Kootenays we do a lot of low speed climbing followed by lot of fast descents.

    Make sure you use ramped chainrings- shimano SLX/XT
