Reddit mentions of OneUp Components 94/96 Round Chainring, 94/96BCD 30T Black

I would go with a OneUp chainring instead. After further investigation you can remove the whole spider and buy something like this

I have a 2018 Trail 6 that I got last November and really love and it's been a great bike to learn on. I have ended up doing a lot of upgrading on and there are some idiosyncrasies to the Trail series that I wish I would have known.

First big upgrade was the dropper post, and that's been awesome. You can internally route a dropper on the Trail series so just find a good deal on a dropper that you like and you're good to go. I was able to get a KS Lev Si used for $100 and it's been solid.

Putting the dropper on prompted me to want to get rid of the front derailleur/shifter and go 1x. I ended up ordering this chainring as the FSA cranks have a weird chainring size. Thankfully I was at a friend's house to help me because FSA does a little proprietary thing with their chainrings and he ended up having to grind a bit around the bolt holes (the flat part towards the center of the circle) to get them to fit. The other thing is that the rear derailleur didn't have a clutch so my friend suggested running the chain a little smaller than stock to keep from dropping the chain. I ran it like that from January to July and never dropped a chain. It also helps that I was intending to upgrade the rear derailleur within the year, definitely not a long term plan as it would wear a lot faster.

So, if you're really set on going 1x, my advice would be to do the cranks and bottom bracket too unless you have access to a grinder and someone competent to use it. I ended up installing a Shimano XT bottom bracket and a used set of XT cranks/chainring this summer and have been really happy with them. I don't know that I can actually feel the difference, but they are lighter for sure. I also upgraded to an 11 speed SLX cassette, derailleur, and shifter and have really loved having the bigger gears (46T) on the hills (also went from a 30T chainring to a 32T).

The other thing to consider is the tool cost if you're doing it yourself. You'll need a tool to pull the square taper cranks and another one to pull the bottom bracket. Then you'll need a new one to install a Hollowtech BB. And you'll want a cable cutter for the upgrade to a 11 speed too.

I've been tracking stock and upgraded parts here, feel free to ask about any other upgrades you're planning on.
