it's very easy to find...
shimano "Do not reuse a QUICK-LINK that has been removed. If the QUICK-LINK is reused, there is a risk that it will loosen and become detached, which may result in an accident." http://si.shimano.com/pdfs/si/SI-0159A-003-00-ENG.pdf
sram, "each PowerLock® is good for a one-time application only" https://www.sram.com/sram/road/technolo ... 1beb9ldtav
...i've removed a sram 10-speed one with link pliers to test (i never use them, for 10-speed kmc re-usable goes on, the sram link goes in the bin), a magnifier shows tiny shards of metal flake off in the process, i.e. the sram link is mechanically damaged by removal
Im using quicklinks since MTB times (i was using SRAM 9 speed, connecting/disconnecting many times with hands, and no problems). Usually one link per life of chain.
When i switched to Road bike and Campagnolo Veloce 10 speed chains, i found a problem in cleaning the chain without quicklink. I used the ParkTool Chain Cleaning tool, but some of degreaser went in the hub, so need to replace bearings.
After that decide to use KMC quicklink and on 10 speed i was able to do it with bare hands, and again use the same link during life time of chain.
Then switched to 11 Speed Record, got KMC QuickLink 11 speed, and noticed that not possible to connect/disconnect with hands, so i order Park Tool Pillars for that. Also realized with Pillars there is less damage to the quicklink then when i do barehands. Now on 11 speed im doing this way.. Ussually chain last about 4500 km. In first 1500 km, im using the original pin. After 1500 km, i ussually do the maintence service and cleaning, and then i put 11S KMC QuickLink until the end of the chain (i do the maintence around 1000-1500 km after that, depend how and where i ride).
On my 9 speed MTB, i just replaced cassette/chain (Shimano XT). I used QuickLink right away from start (i ride more dirt with MTB, so need more often cleaning, so that way from start).
I guess every disconnect/connect of quicklink, make it weaker (using pillars definitly do less damage), but based on my experience not weak enough to trow it away after first connect/disconnect. Until now, never had a problem with quicklink to snap or something.But still, i'll use new QuickLink on every chain change and will use Pillars for that (definetly more secure connection and less damage then doing with hands).
Another thing im wondering if we use QuickLink other brand then the chain. Does it affect shifting performance or not?
