Question on quick/master links

[DRZRM]

So I have a 9-speed Dura Ace chain lying around that I'd like to put on my wife's road bike for Spring cleaning, but in my tool box I only have Shimano 10 speed, Campagnolo 10 speed, and Campagnolo 11 speed links (I think all KMC, but I can't remember). Don't suppose I can just use any of these instead? I figure no, but before I head out to the shop or order a pack on line, I would ask.

In theory you should be able to do it as the teeth spacing is the same in width only the side plates are thinner in width making the chain narrower overall. However I have not ever tried so can't say how it might work.

Sounds like a job for your LBS. I just got a 9 speed quick link for like, $3.

Like, theoretically it would work. But the plates are thinner on newer chains.

And thinner plates are flexier.
At a critical place in the chain.
Not a risk I would take to save a couple bucks. (And I'm cheap as heck.)

So you draw the line at 9s drivetrains?

I only moved to 10 speed when my 7700 shifters died.
Seriously, flexier thinner chains are fine, as long as they are consistently flexy.
But one flexier link (or half-link) among 117 relatively beefier links, right at the quick link, sounds like trouble.

I'd do it as a stop gap to get home if my chain broke during a ride, but not as a long-term solution.

Makes sense.

Links are too narrow for 9s chain, won't be able to hook it together.
