Am looking for a BB30 or GXP 170mm crankset with 29/36 rings. Or separately.

Normal Q factor though.

Preference would be for X0 or XX, but open to alternatives.

Cheers,

Lincoln

unusual combo, there will be a huge amount of duplication

XO/XX generally run 26/39 or 28/42 (i ran a 28/39 set up for a while)
i don't think the standard spiders on X0/XX will run less than 38t on the outer
there are after market options though, Home Brewed, Wolf Tooth, etc

104mm BCD cranks are probably your best bet for 29-36
but
your front mech won't work as its designed to if there is less than 10 teeth differance between ring sizes

maybe just give 1x10 or 1 x 9 a try?

I've got a 37 renthal in 120BCD, but that's the smallest that'll fit.
 
I have some XX cranks i want to get rid of

GXP, pretty sure they are 170mm will check, 39/26, 56 Q factor

After $100 plus postage if your not in Sydney
