Multiple master links on the same chain Not so long ago I put a new PYC SP1101 chain on my bike, but several rides in I managed to snap the rear derailleur off, which also bent a bunch of chain links. No way I'm throwing a perfectly good, albeit now shorter than needed chain away, so I decided to replace the bent section with leftovers lying around. The chain has hollow pins, so I can't just pop one out and push it back, that only leaves master links to connect the fragments, which I should have three of (all are the same, included with PYC SP1101).

Are there any potential downsides to multiple master links to be aware of?
Nothing wrong with it other than aesthetics.

I have 3 master links on the 2.8 metre chain in my `bent.  Its glaringly obvious too cos the masters are shiny chrome and the rest of the chain is a dull cheap galv chain.

There might be a few grams difference in weight too, but realistically that's probably less than the weight of dirt on your bike.

Just use the same brand/style of master link, so you don't try and take one off the wrong way.
