I want to replace the 38T ring on my Sram XO 2 x 10 crank/spider with a 36T. I have a brand new 36T Shimano 9 speed kicking around (FC-M665 dual ring specific) and was wondering if that would work without issue? Both have the 104 BCD. This would give me a 24/36 combination.
I'm thinking yes as I know you can use some 9 speed stuff in the front with 10 speed out back but I have no personal experience trying it out.
