I have a Kona Jake cyclocross bike with a Shimano Tiagra 2 x 10 setup. I have never liked the pendulum swing action of the Shimano STI shifters. I prefer the SRAM double tap. I have purchased a SRAM GX 2 x 10 long cage rear derailleur and a SRAM PG1070 10-speed cassette cog. Will be purchasing a SRAM GX 2 x 10, bottom swing, top pull front derailleur. I am hoping to use SRAM Force double tap 2 x 10 shifters to complete the SRAM swap. Will this setup work? Please advise. Thank you

Yeah, I think that will work. I think SRAM 10-speed is all 1-1 ratio on both MTB and road shifters and dérailleurs. Shimano is all over the place making mix-and-match tricky but SRAM is all the same.

Yeah, it works fine. I broke my Force 11 rear derailluer and replaced it with a GX 10 because I like the clutch mechanism and I wanted to run a larger cogset.

I know that SRAM uses a 1:1 pull ratio on road and MTB components, but I don't know whether or NOT that 1:1 cable pull ratio is exactly the same on both road and MTB components or whether or NOT you can mix road/MTB components. Specifically, this is my concern. Also does anyone know whether SRAM Rival and SRAM Force double tap road shifters are compatible. I am hoping to purchase SRAM Rival 2 x 10 carbon double tap road shifters to replace SRAM Force double tap road shifters.

...but I don't know whether or NOT that 1:1 cable pull ratio is exactly the same on both road and MTB components...

Yeah, 1:1 is 1:1. That's the whole point. So if you've got a 10-speed 1:1 shifter it will work with any 10-speed 1:1 dérailleur. Road, MTB, clown-bike it doesn't matter. If the number of speeds and the pull-ratio are the same it will work.

In fact it's just the pull-ratio. I'm using a 3x shifter on a 2x crank on my road bike, the pull ratio is the same so it works.

Yeah. In Sram's parlance, 1:1 means the length of cable pull is equal to the spacing between the cogs.
