New Chainset, terrible noise! (Video Included)

[nulleth]

Hi all.
Cannondale Synapse, it's 3 months old, and the FSA Velo chainset was terrible so I replaced it with a matching Sora one. Unfortunately, the noise worsened!

Shimano 4600 Hollowtech BB, Sora Chainset, Shimano HG93 chain. All brand new.

In the video I move from middle rear, to smallest rear. The noise is heard in the first section, but becomes incredibly loud at the end.
The noise is coming from when the chain contacts the chainring teeth.
It happens most in the large front, small back, but is heard in all combinations.

I'm certain that's where the noise is coming from, I've had my ear to it and even moved the front derailleur out the way to confirm.

Old parts (but new), noise is there.
New parts, noise is worse.

Is the frame bent, does the bottom bracket mount need facing, what's going on?
Please help, it's driving me crazy.
Thank you.

All I can hear/see is your chain rubbing against your front mech
What chain are you using ?

Indexing is out of adjustment.

Sadly, as I mentioned, it isn't.
I can fit card behind it and no lube touches the card. Second to that, I've moved the entire cage out the way and it still happens.

I also mentioned I'm using a HG93 chain.
I don't think you read my post.

sounds like chain is out of alignment , does the chain try to "change gears" when you back pedal

I've watched the video a few times and right at the very end it looks like the chain is hard against the front derailleur.

Right, but again, I've tried move the ENTIRE FD out the way. It's 1000% not the FD.

That was my thinking too, it doesn't do anything different while back pedalling. Any other tips to check this?

I am right in thinking you have ten speed shifters/cassette on HG93 9speed chain

Everything's Sora, all 9 speed.

You say the bike is 3 months old .. new or second-hand

Wot he said (especially if it isn't, as you say, hitting the front mech). Look for the Park Tools how to index gears video on Youtube.

That's an indexing noise from the rear, not the front..
