A little more info. Looks like there are two versions. One for road and the other for gravel. Going above 12 gears is a little crazy, but this is an interesting idea. I'm hooked on wireless, using AXS for a couple years now.
I'm very sorry to hear that you're going through that. I got really lucky. Five stents total completely fixed me. The thing I hate is taking Metoprolol. It keeps my heart rate low and that can affect my riding. I hope you can find a happy path.
