Well what can I say other than it’s a great bit of kit. I had xtr manuel shifter before and that was very good. But this is another level of good. The shifting is rapid if you want it or slow if you want it. The triggers are front facing so I use my thumb for both. The feel is not to easy just right and you can change without changing hand position to go up or down as few or little gears as you like. None out there better. The only thing I am finding is the battery gets stuck up with sand and you have to lever it out so make sure you clean it after a wet ride. Overall top kit once you have used it you will not go back to cable.
