I got up and rode but I was way sub par. Today the leg is basically in pain with anything other than a straight leg, my quads is swollen but not bruised yet. such a nice day and no riding :(.

 

There is a new chain on that bike now, and the old chain had stress fractures on other parts of the chain as well. the sad thing is after destroying a ton of BMX style chains, I found that SRAM(or shimano) 8 speed had a better design with modern bushing. .

 

Dont know a solution really. Besides the not pedaling as hard one.

How often do you change the chain? Do you check em for stretch?

......we all know they don't stretch, they wear  wink.gif

When the chain starts to skip, unless I have another old bike I can ride insteadbiggrin.gif.   Those parts cost more than the bike cost me!

 

I have noticed that things wear faster when a new part is matched up with an old one.  New sprockets with old chain will cause the new sprockets to wear faster.  I suspect the new chain will wear faster if it's put on old sprockets.

Yup.     Change the cogs if they're sharkfinned.

the thing is even the intact pieces of this chain did not have bushing wear. there was other stress fractures on some other links that did not let go yet.

That's a bummer.  I wonder if you need to take a microscope to inspect the next chain you buy.

58, still debating if the higher series would actually be stronger.

maybe you should try the Wipperman SS chain. Or... just replace your chain twice as often.
