Hi recently replaced my derailleur hanger and cassette. Now my chain sags if I drop into the front small ring and go down in the lower gears on the cassette..
Should I remove one or two links?
Thanks.

Needs to be in small ring to tell. If the chain isn’t having all the slack taken up in small small, it’s to long.
small – small should be under tension. Remove some links until it is. There is also the ‘correct’ way to measure Shimano chains.

Edit: better link showing all the different variations. I hadnt realised I’d shared only the MTB ones. Apologies.
Probably – but I would need to see big-big to be sure it’s not the derailleur.
Yes but that’s not your biggest issue here… don’t take one more pedal stroke until you change that outer chainring.
It never stops amazing me that posts like this exist, and its about half the sub at this point. 1 short search will get you a fuckton of great videos explaining all that you ever wanted to know about chain lengths and how to install them correct. But people take the effort to make a post, take pictures, upload said pictures etc. Hey here is my complete shitbucket of a bike which has clearly just been drained from a pond after lying there for 10 years, should I change the brakepads? No offence if you are for real
Yes
How did it get like this? Has it just been fitted? Usually you measure against the old one to make sure you have the same number of links.
