SRAM 11 speed 1x shifter compatibility

[bobalou]

I got a SRAM x-horizon rear derailleur all setup on my bike (with proper 10-42 Sram cassette and HD body). I thought the SRAM Rival "zero loss" 22 brifter would work with this but it appears not to have the correct pull. https://www.amazon.com/gp/product/B00L6SBUW2/

I don't want to use a trigger shifter. I find the SRAM website not particularly helpful .. any suggestions on the correct brifter, even a link to a website selling it would be great.

which xhorizon rear derailleur? Is it a road rd or a mtb rd?
Road 1x and mtb 1x are not compatible.

A road 1x rd will shift correctly with all 10 and 11s road brifters

If you want to keep your rd and its a mtb rd, you will have to look at cable pull adapters

Force1 rear mech is what you need

Edit: or I think there is also a rival1 now?

[silvalis]

force1, rival1, apex1 too

It's a MTB derailleur. I had thought the "x-horizon" had the same pull for road and MTB 1x derailleurs. I guess not!

I found this and ordered it. https://www.sjscycles.co.uk/cables/0-jt ... 9/?geoc=US

Exact actuation is what you are looking for.

10s MTB derailleurs will work, the newer 11s "X-actuation" ones have a different ratio, but now there are the "road" equivalents mentioned above.

I think X-horizon refers to the offset top pulley and the pivot point not moving much?
But yeah, Exact actuation is the pull ratio (mtb 10, road 10, road 11)
X-actuation is mtb 11 and 12.
