I put an 11-40 cassette on my grx 400 set up and I was hoping to get some more opinions on whether or not I should go shorter on the chain. It definitely seems like I could since the derailleur can go a lot further forward when it’s in big big. I don’t ever run that combo just trying to make sure the chain is right. Thank you.

Yeah I’d add a link.
Would you practically ever ride like that? Probably no. And theres still some play if you would
That honestly looks fine. I would not touch it
Do you run this same cassette on the actual wheel? You probably don’t need this range for zwift. I guess that isn’t the question here though lol
It looks fine, just keep it
You can make a little tool out of an old spoke or metal coat hanger, just a wire with two bends to make hooks at each end, that will hold tension on the chain between non-adjacent links so you can see what it would be like if you took a link out.
My 2 cents – it looks perfect.
As long as you still get enough tension from the derailleur in the small/small gears (it looks good to me from the pic), I’d leave the chain as is.
As long as there’s a tiny bit of tension in the derailleur and chain in little/little then you’re good. Looks good to my eye.
Traditionally your setup looks perfect.
On the big-big front and rear rings, the derailleur cage should be at about a 45 degree angle…and that’s what you have.
Going a bit short is a disaster…better a bit long than short.
Looks good!
Looks perfect
Chain looks fine. The upper pulley wheel looks too close to the climbing gear when in big-big. A b screw adjustment to a 5mm gear to pulley gap may help low gear shifting and reduce wear.
I’ve never seen a set up like this but I never really work on really new higher end bikes. What is the use case for so many gears on the rear cassette and for such enormous cogs? It sort of looks like the small chainring is much smaller than the biggest cog.
Does the derail take up all the chain in SMALL/SMALL? That may provide some answers
Small small and derailleur is level. It’s mint
is your groupset grx 400 stock or did you make any modifications? i am wondering if the 11-40 works good with stock groupset or should i look into goatlink?
Follow Shimano’s instructions if you want the correct answer.
