    Chain slip woes

    So.

    My chain is being pretty annoying.

    I replaced the chain and cassette over the winter. I noticed the chain slipping, particularly on rough surfaces and when I'm really on it. Figured chainrings.

    Then last night my dad commented that the chain was doing a lot of flopping and looked wicked loose when I rode. Hmm. Pop it off and lay it down next to the old one, a few inches too long. Hmm. Take off two links so it's as close as it's gonna be to the same length and put it back on. Now it is absolutly awful. It slips under any stress. If I gently pedal in a low gear it'll only do so every couple of turns. It's making a pretty steady tick somehwere down there.

    So, chainrings? They're original on a 2003 so I figure they're due. Also, the chain is a just a bit longer. It would be exact if I took off a wide link thing but then I couldn't close the chain.

    Thoughts?

    SRAM cassette and chain, Suntour cranks (dunno who made the chainrings). Would different companies make a difference?

    Is this the first chain replacement you've done on this bike? If so, it's probable that the original chain wore down the chain-rings to the point that the chain-rings just won't mesh with a new chain anymore. I'm assuming the slipping is occurring on the chain-rings and not the cogs?

    tell us more about this tick. is it there when not pedaling? is it there at a certain point in the pedal stroke?

    you may have a stiff link in there somewhere. maybe you squeezed the pin too tight when you put the chain back together. just tossing that out there as a lower cost issue than replacing the chain rings.

    I had a slipping chain. Replaced the freewheel. Still bad. Replaced the chain. Still bad.

    Cursed hawed and cried, still bad.

    Replaced rear Derailleur, problem solved. Shouldn't have made any difference, but it did.

    the wheels in the mech wear down.

    also the pivots wear.

    Yes this is the first replacement. That's about what I'm thinking.

    The tick is constant when pedaling, not there when I'm not. I haven't had a chance to pinpoint where it's coming from but it seems to be from the cassette/derailleur area. I'll have to look at the stiff link idea as it's pretty possible..

    Hmm, interesting.



    Thanks for the input

    I also have a theory that not all cassette/Der/chain combinations are created equal. For no apparent reason, some combos just don't work quite right...

    I found a stiff link. How do I un-stick it?

    Just grab the surrounding links in your hands and work it back and forth, up-and-down, etc. Put some oil on it. Repeat.

    Wear gloves or have some heavy-duty hand-cleaner nearby!

    I use this stuff



    Anyway, That made some pretty significant progress (At the beginning I could barely make it move, now its pretty close to what it should be). After like 45 mins I got bored, though haha.
