I have what apears to be a link in my chain that is very tight and dosent flex at all it dosent ride tight over the derailer but causes a miss or jump resulting in free pedal,,Ive tried saturating it with liquid wrench but its still stiff any procedures for loosining it
Do not ride the bike until you fix this problem. Riding could cause serious damage to the derailleur and even the frame.
Work the stiff link with your fingers until is loosens. If you are unable to do this then use a tool to pry the links slightly, just enough to loosen the link until it is exactly like the other links. The amount of pin exposed outside the links should be the same as the other links.
One of the tricks to loosening a stiff link is to bend the chain, with the stiff link in the middle, side ways.
Grab it on each side of the link with you hands(you'll get dirty doing this), and bends it slightly back and forth. It may free it, or it may not, it depends how stiff it is, and why.
I had this same problem in several places on my chain. I had a bike shop check the chain for stretch/wear and they said it wasn't. They did the sideways flex thing and relubed. About an hour later the links were kinking up again. I used a chain break to remove the chain then scrubbed down the chain in a parts washer and reinstalled. I then used the chain break tool to partially push out the pins on each stuck link and then reseated the pin. I had to do this a couple times on a few of the links. After lubing it again, the chain is now good as new.
