Even then it depends on the brakes- Basically, the Reverb lever is designed to work with a matchmaker on a SRAM brake, which means the lever mount really wants to go exactly where most brakes go. And it’s fairly bulky and picky about angle so it doesn’t play too well with some brakes.
I can’t get the remote exactly where i want it with any non-avid brake, but I can get it close enough. It’s kind of a pain tbh. If you look at, say, KS, they didn’t shoot for neat perfection like Rockshox but it’s a more flexible lever option, whereas the Reverb lever basically has one perfect location but often can’t go there.
