Lenghthy chain question

Hello friends, I need some wisdom. I am going to a 52t chainring from a 48t and I need to add 4 links. I got the brilliant idea to just use another new power link and short piece of chain. So I would have 3 power links running altogether. If it was an ordinary chain I'd splice in the extra links and be good to go. However it is a KMC extralight 9spd w/hollow pins. That dang thing had my chain breaker fearing for it's life. Hardest chain to break I've ever worked with. Also in case the 52t ring does not perform to my liking the mod would be easily reversible. If it all works well I can splice in the extra links later. Do you all see any problems running 3 power links for a limited time or is that taboo?

Thank you kindly, MAC

 

For obvious reason, I have 3 standard cycle chains merged together with what A.D. posted above + one extra-easy-to-unjoin piece. No problems with chain for already 4k km.

In your case there could be an issue with majority of the chain being already worn (somehow) and that piece being "new". That can (in theory) cause irregularity in running the chain.
I'd say, unless you are really tight on budget, buy a new chain for this test. It will give you clear results if change works for you or not and either way, chain is consumption material that you will need sooner or later anyway, so no money lost...

 

Yes, I would agree with this method too. "It's the only way to be sure..."
