My rear 8 speed derailleur broke in a crash and I want to upgrade to the Shimano deore 1×10 drive train but I’m not sure if it’s worth it for almost $300? Is making the switch with it? I have a trek marlin 6 and upgrading would be half the cost of my bike.

Totally not worth the $$ and labor.
Get a new derailleur for 20 bucks (https://www.cambriabike.com/products/shimano-altus-m310-7-8-speed-rear-derailleur?gclid=EAIaIQobChMI7pux4rbh4QIVA56fCh1PIgPnEAQYBCABEgJ8P_D_BwE) and ride that bike as hard as you can. Save your money for your next bike.
And happy Easter 🙂

Depends how you do it. Zee shifter + SLX derailleur + sunrace cassette should be under $150. Can you put a narrow-wide ring on your current crank?
I considered doing this piece by piece but wasn’t sure if 10 speed derailleur would work with 8 speed chain. So I went with a 11-40 8-speed cassette. First ride went well but I need to hold my chain better. Either device or narrow-wide needed. Thought about using old derailleur fixed in place but I think there will be too much up and down play.

I did a Shimano 8 to 10 speed upgrade about 2 years ago and it works great. If you shop around a bit, you should find a new or slightly used 10 speed SLX and new chain and shifter for under $150. Also get some new cable to go with it. Takes about an hour.

It’s only going to be worth changing if you get a wide range cassette. Get an 11-46 cassette minimum and 11-50 would be better. And why limit yourself to 1×10? Why not 1×11 or 1×12? They all fit on the same hub. By the time you buy a new cassette, derailleur, shifter, chain, cables, and chainring, your going to spend some green. Given the cost of your bike, it might be better just to replace the old derailleur. However, if you old drivetrain is already pretty worn out and you need a new chain, cassette, and cables anyway, on top of replacing the broken derailleur, now might be the time to switch to 1x. I like the the Sram Eagle NX 1×12 with an 11-50 cassette which is suprisingly inexpensive. Also check out the cassettes at Sunrace.
