The chainring is of course getting more wear in a 1×10 setup though
That is true but you can use an unramped ring and reverse it when worn. Unramped rings also tend to be a bit cheaper as well so you’ll reduce your costs.
I’m running 1×9 and will go to 1×10 once it all needs replacing. What I’d be interested in is if anyone sells 10 speed rear shifters as single unit rather than as pairs. Judging by the amount of 1x threads on here there must be a lot of front shifters in peoples spares box.
Edit
I’m still running the ramped middle ring and a long cage mech and haven’t shortened the chain at all and it’s been fine for xc riding. I’ve a bash ring and an old light bracket bodged as a jump stop.
