New 11 speed DA chain on drivetrain with less than 1K miles buckling/sucking/existential crisising after hard peddling in the largest front chain ring and smallest rear cog combo. It seems to only happen when pedal pressure is released.
Checked so far: chain length, direction, and orientation, master link seating and orientation, rear derailleur B screw gap and seating on derailleur hanger. Still folds after pressure is released like it’s in a high stakes poker tournament. Does anyone have an answer to the problem?
New chain buckles like Cowboys at the playoffs

It’s because your freehub isn’t spinning freely enough for when your wheel is spinning that fast.
If it’s a new freehub then this will stop happening with some use. If it’s used then it may need to be cleaned and regressed.
Check and grease the freehub. The noise will be quieter though.
Service your free hub.
Service the freehub or trade your freehub to Green Bay and then get an inferior freehub on the used market 🤣
That’s likely the freehub and not the chain
I just have to give you props for the analogy!
Cowboys out here catching strays
My dt Swiss’s were doing this day one. Still happening, never broke in. Only about 1300 miles on them.
Edit: replied in the wrong spot
Does it do that while riding? Odds are you’ll never get the wheel spinning that fast on a ride.
Yeah, that’s not the chain, that’s your freehub.
Doesn’t seem to be a lot of tension on the cage
What kind of rear hub is that?
old mavic hub? sounds like a “mavic death screem/squeal”
Freehub is cooked
Your free hub is messing up basically allowing energy in the wheel still move the cassett a lil
So if you watch pro cycling, and especially when Mark Cavendish was sprinting.
This almost happened every time he went over the line.
He was sprinting so fast and just when he throws the bike over the line and stops pedaling. This happens….
I see a yellow flash on the hub. My guess is that it’s an older Mavic hub. They are all super easy to service, no new parts needed. The hubs came apart 2 different ways depending on age and model, but there is a nylon ring in the cascette body that gets coated with super fine road dust over time. You have to clean and re lube that nylon seal. Any local bike shop should be able to help you. If not, and if it is a mavic, DM me and I can ask you a couple questions and walk you through it.
