KMC Quick Link on Shimano chain
I bought a second hand Giant TCR recently for everyday duties. Went out on it this morning and impressed by how quiet the drive train was. It is Ultegra 6600 with a Shimano chain. My other bike has Ultegra 6700 and a KMC chain. 6600 was silent and 6700 is always a bit noisy. When turning the cranks while the 6700 bike is stationary the chain moves in a very notchy way around the jockey wheels and sprockets as if it doesn't quite fit the teeth . I'm wondering if it setup or that KMC chains are just noisier due to not being shaped ideally for Shimano sprockets. The main reason I use them is because they can be removed easily for cleaning. So is it possible to use KMC quick links with a Shimano chain and get the benefits of both?

Sounds like the set-up is sub-optimal and/or parts wornFFS! Harden up and grow a pair0

Regarding the "notchy" feeling on the jockey wheels. I have the same thing on two road bikes. Just like the pitch of the jockey wheels is wrong. Can't comment on the 11s groups, but certain era derailers seem to do this. I use Shimano chains BTW. Same issue with a 9s chain (dura ace), or 10s (6701). Don't think changing the chain will solve it.0 -

Unnecessarily long answer... Yes it most certainly is the case that a KMC link can be used successfully on a Shimano chain.0 -

Yes and No.
It will fit, but I had a problem with exactly this combination. After fitting an KMC quick link to a Shimano 10 speed chain, I was getting a regular click, particularly under pressure. I could not find the issue initially, but with the bike on a stand, I noticed that when spinning the pedals backwards, the link was slightly catching on an adjacent cog on the cassette.
It appeared that the link was a fraction wider than the standard links on the chain.
I swapped the link for a SRAM one and the problem went away.

It is important to use the quicklink that is designed for the chain size and gear configuration. The quicklinks come in 8/9 and 10/11 speed versions - the 10/11 speed ones being thinner than the 8/9 to match the chain plates and cassette spacing - maybe that was the problem?Wilier Izoard XP0 -
WHAT? 8 (marked 7s as the chain is the same) and 9 speed are different, and 10 and 11 are as well, so that's 4 different links not 2!
Look at the link it will say ONE of 7s,9s,10s or 11s on it.
That doesn't rule out having a link that is wider than it should be though.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -

oops! - my bad but the same principle appliesWilier Izoard XP0 -
I have 9 speed on the winter bike and 10 speed on the summer one. Annoying to have to carry two different sized KMC links in my tool kit.
Then somebody suggested I just run a 10 speed chain on the 9 speed bike. Genius!0 -
I run a 9 speed chain on my 7 speed bike with 10 speed shifters! But it does have a 9 speed quick link so everything works just fine.WyndyMilla Massive Attack | Rourke 953 | Condor Italia 531 Pro | Boardman CX Pro | DT Swiss RR440 Tubeless Wheels
