Please school me on the shifter ratios. I am dumb and have confirmed nothing regarding the interoperability of these parts. 3 in the front and 9 in the rear is all I have been going on.
Im about to crash for the night so not an in-depth answer but pull ratio refers to the amount of cable the shifter 'pulls' for each index vs. the amount the rear derailleur actually moves. If the shifter and RD aren't matched you will never be able to index all the gears correctly. Shimano doesn't publish this info but I've seen it on third party sites. So far as I've seen road and mtb stuff is different. You're talking 9sp though and nearly all my stuff is 11sp. I'm not saying it won't work, only I know other stuff definitely won't, so just a suggestion to double check.
