BS (no, really) I agree with Bill, but I think that everyone visualizes this in a slightly different fashion. Here's my "vision": 1. Get the chain on the small chainring and the small sprocket - so you have the easiest slack situation to deal with. 2. Fold the chain so it makes a "U" - with only the powerlink at the apex. Yup, your hands get grungy at this point. 3. I do this with my left hand, as I am right handed (you'll see why in a second). 4. With your left hand(still isolating the powerlink in a "U" shape), take your thumb and index finger and squeeze the two side plates of the powerlink together (i.e. push the two large flat surfaces towards the center of the chainline) and hold. 5. Now, while looking top-down on the rectangle that the powerlink makes, take your right thumb and index finger and push two diagonally opposite corners towards each other. 6. And, voila!, the links should magically slide towards each other. 7. Now, pull the two slide plates apart. I hope that's not too overstated and confusing. Once you do it a couple of times you'll wonder why you ever asked. But, then you'll wonder why anyone would ever not use this type of system. And, then you will have your own version of how to perform this motion. Wonderful ;-) -- spin |

BS (no, really) Do you mean "pull" like when you free up a sticky link after re-riviting a chain? Well, in that sense it's more "push" I guess. Press your thumbs /inwards/ while at the same time squeezing the QL. Hell, wait a second... "The powerlink is very easy to use; just squeeze the sideplates toward each other, then push the ends of the chain toward each other. This removes the opposing tension which holds the link in place and the link pops right out with the flick of a finger." -- some MTBR person A trick I use is to ziptie the derailleur cage to the chain stay, taking out all tension so it's easier to manipulate the chain. Keep trying! |

Per Bill Sornson:
Play around with it a little; you'll get it. I agree. Thought it was a real PITA until I got a feel for it. Now they just come right apart. -- PeteCresswell |

alternate trick for wrestling with a PowerLink
A trick I use is to ziptie the derailleur cage to the chain stay, taking out all tension so it's easier to manipulate the chain. I made a reusable tool out of a coathanger. I cut a six inch long straight piece and bent the ends into slightly more than 90 degree hooks. After shifting to the smallest cog and chainring, I pull a short loop of chain centering on the PowerLink and then use the wire hooked through the chain on either side of the loop to hold it slack. Makes it very easy to concentrate on opening the link without worrying about where the chain is going to slip once the link is open. Likewise, when reassembling it holds things together while you focus on closing the link. There's no tension on the link until you remove the wire. Pat Clancy |

SRAM powerlink question
In theory, the various directions given should work. Except that ever
since SRAM took over the design from SuperLink, the two plates have NEVER "easily slid" anywhere. I always have to use pliers ti get them to click into their respective positions. - - "May you have the winds at your back, And a really low gear for the hills!"

I always have to use pliers to get them to click into their respective positions. Well have you removed the tension off the chain? I take the chain off the chainring plus a little bit of lube will help. My first one was like that but since then I can do them with my fingers. This has come up a few times. To disengage the link, (made of mirror imaged parts) both side plates must be pushed together the amount of the lateral clearance between link plates... that clearance that allows the chain to bend sideways to cross over between chainwheel and off center rear sprockets. This allows the mushroom heads of the pins to disengage the recesses in which they reside. Plate clearance is reduced by road grit with use, preventing pushing the plates together enough to allow the pins to slide in their slots. Using pliers diagonally across the link at the fixed ends of its pins will simultaneously compress the link and slide it toward the open position. Only in pristine clean condition does this work easily manually. Jobst Brandt |

I can't recall the exact words, but you mentioned in one of your articles that you had a quick disconnect chain link come lose in the 13t cog because it was covered with mud and actually dislodged the connector? Was it because of the smaller diameter cog pattern you were riding in, or the mud itself, or both? -tom |
