i added a McCruise control and made my 2018 tubeless. All I'm missing is the fancy dashboard. I've got about $12k USD tied up in it. I have Heed crash bars and a Seat Concepts seat. Not much else I plan to add to this bike. I'm ok with not having a 2020.
You only need to add a "serious" rear shock and you'll be ok for some years! That's what I'll probably do with mine MY2018 Standard AT.
