After taking off the LTWOO er9, I put on Sram Rival AXS and clocked the first 100k with it.
I’m using the exact same chain, cassette and chainrings. Rival shifts quieter overall on my setup. Front shifting is better. Never thought I’d say that of a Sram FD. Not having to trim the FD because of the yaw feature is nice. But I gotta say, it’s so close that most of it like ergonomics and Button Feedback is really a matter of taste.
Most of the things that Rival does better comes down to the software. Customisable Multi Shift. The fact that the groupset drops into the small ring if you cross chain too much. The way that the FD overshifts onto the big ring and waits for the chain to drop onto the small ring before it moves all the way in. That could easily be implemented by LTWOO as well but I reckon that patents prevent them from doing it.
