Bicycle chain removal and reinstall, safe?
I just replaced my chain, and I made a mistake that required me to remove the new chain and reconnect it.
To do this I simply removed an arbitrary pin (not on the spot where the new joining pin was), then reinserted the same pin in the same spot. This is a KMC Z72 chain on a mountain bike, if it should matter.
It seems to work fine, but is this safe to do? Did I just ruin the new chain and will I have it fail prematurely?

incazzare.
I have done it 100 times. If you put it together correctly you are fine.
edit: I'm assuming it's a 5-7 speed chain here.

Kind of. It has mushroomed pins that aren't meant to be removed and reinstalled. You might be able salvage the chain with a quick-link for a couple of bucks. Remove the affected outer and replace with the quick link.

I use a quick link on both my bike and trike. They make it easy to remove and replace a chain.

Yes.
To Push a riveted (mushroomed) pin out you stretched the hole in the Side Plate
Z72 » KMC Chain
So Odds are It will come apart there when you shift hard in the woods enough times .
If you cut it removed the outer link , put a Quick Link in ,
instead of pushing the pin in the likely hood is reduced ,
because as it is the pin fits loosely in the link plate hole.
and the pin head is nearly flush with the face of the side Plate .
BITD , 6 speed era the chains were different.

For some reason I assumed it was a 5-7 speed chain due to the chain model number. Yeah if it's an 8+ speed chain, use a quick link.
