One thing to consider is that if you don't use a bashguard or chain guide, it's pretty easy to drop the chain on a 1xn. The rear derailleur throws it right off the chainring unless you slow you pedaling way down for a second. So you might want to consider a bashguard or chain guide. I didn't want that, because I like being able to wipe off my chainring, so I just got used to letting way up on the pedals every shift.
