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?
