I've had mostly the same experience (hands only), but I've had trouble with /a few/ grit-encrusted links. Spray with WD-40 and wiggle the link a bit to flush and shake the grit out, so that the side plates can then be pushed closer together. On some links it /does/ make a difference. Mark J. |

I used to find them very hard to undo and reached for the pliers on a couple of occasions, but now I can just pop them off by hand in seconds. The trick is to squeeze and slide at the same time, holding the link in the middle. Wipe some of the oil off first because you do need a little bit of grip. If you just try to pull the rollers apart without pinching the two sideplates together (squeezing) you need much more force and who knows might damage the link. I don't like the idea of putting little nicks into with the pliers. |

I took a six inch length of coat hanger wire and bent slight hooks at both ends. When I want to remove chain, I position the connecting link roughly in the middle of the bottom run. From the top of the chain I set one of the hooks into a link about three inches to one side of the connecting link.

No slick chain slipping through your fingers running off of the chainrings or cassette as you try not to drop the link halves. It's perhaps even more useful holding the chain in position when installing the link. It took all of one minute to fabricate the tool and it takes five seconds to use it. The problem is, it doesn't look very professional. I wonder if I can convince Park to produce a stainless version with a rubberized grip? Pat Clancy |

You can do it by hand, by hand with one pair of pliers, or with two pairs of pliers, depending on how difficult it is to unsnap. I've had some that were very easy and some that were nearly impossible. Cleaning the link often helps. One trick is to bend a stout wire into a "V" and use it to squeeze the pins together while pressing the side plates with pliers. |

I can as well AFTER I've opened them a couple of times. But that also means that it is getting loose. And for the record I have had one come undone while riding. I sometimes carry a spare masterlink in case now. |

True grit is where it's at! I take the chain off the chainring so it is entirely slack while performing these operations. As I mentioned, the side plates must be pushed together taking up lateral operating clearance of the chain for the link pins to disengage from their retention recesses. If that operating clearance is contaminated, it doesn't allow enough movement to release the pins from retention. To put this into perspective, I reported a failure to remain closed for these links here on wreck.bike while back. I put on a new chain using the manually separable link and rode to work without giving my worn sprockets any attention. While climbing a short rise in a 13t sprocket, the chain skipped exactly at the moment the master link was approaching engagement. Inertial compression when the chain re-engaged the sprocket, disengaged the master link, allowing the chain fall to the road. I walked back to the place where this occurred, found the link halves and re-installed the chain and continued riding. I rode that chain for many miles after that and installed new 13t & 15t sprockets to prevent chain skip. I'm sure archivists can find that report. Jobst Brandt |

You might assume it's a matter of mechanical aptitude, but perhaps you just haven't encountered a tough one. I've had one or two that wouldn't even close when brand new and clean. |

And there was me thinking they were the work of Satan. I must say, when they come apart they are brilliant, but I've now gone down the route of a nice chain tool, which fixes most things, and a powerlink in the saddle bag for emergencies. |

Add a little sticky grit and that doesn't do the trick. I use the method Tom Kunich describes, though I worked it out for myself by trial and error. Chalo |

I wonder about the pretense that these links don't have a great deal of variation between them. Some fit right together while others require you to pedal them pretty hard before they snap into proper alignment. Same for coming apart. |

You've convinced yourself that the hard way is the only way. I can't really explain the trick well, but basically get the chain loose, make a Z with the link as the slash on the Z and apply a "shearing squeeze" to the links. ( Smear the link, not squeeze it.) It took me more than a few tries to get this, but once mastered it's worked with every 9sp SRAM chain I've used over the last 6 years. _ Booker C. Bense |
