I never implied that it was “dangerous” to push pins back in but it can lead to chain failure on more modern chains.

There also is nothing keeping people from using 6/7/8 speed quick links on old 6 speed chains. It’s still a better way of putting a chain together.



Well thank you for making my point.
Would you at least read the thread? Dedicated 6 and 7 speed chains have an inner link width that exceed the pin dimensions of 8 speed quick links. So there is something keeping people from using them.

Connex makes quick links for 6 speeds.

Connex makes a snap link for their 7 speed chains. It is not a Connex Link and it may not be reversible:

Where do you do you see 6 speeds mentioned on their website?

Just for a little more clarity, 5 and 6 speed chains are one width, Ultra 6, 7 and Campy/Sachs 8 are another width, SRAM/Shimano 8 are narrower still, and then there's widths for 9, 10 and 11. There are multiple 12 speed chain widths.

I had a bunch of OEM Sedisport and some Sedisport Silver, all used now (unless I find some stashed away) but I still have them on some bikes because they don't get ridden much. I need to spend less time online and more time on bikes.

Yes, but no longer.

Shouldn't, but in my experience can be if you're careful.

They are also just easier to use.
I can probably split and join a chain in the time it takes me to find the quick link on a dirty chain.

What does being careful have to do with any? The side plates are too thin to reliably retain a link pin through friction.

Unless you mean 'careful' by not riding the bike

Not if you were waxing your chains. :)
