Chains Stretch?

[Rapstar]

(mymaster @ Sep. 17 2007,01:40) OK, I had this heated debate with a riding buddy of mine about chains needing adjusting.

He says - they stretch.

I said no, the chain and sprockets contact surfaces wear down - causing the looseness.

anyone?

Pic is to illustrate a point.

Yer both right

Technically chains do not stretch, but the pins wear out. Thus the appearance of chain stretch.

Your buddy has gone WAAAY beyond the service limit of the chain, which is why the sprocket looks like that.

Ps: you can lube the chain all you want, the 'real' lube is sealed by orings and thats where the wear occours. Applying lube to the outside is mostly to prevent corrosion. It cannot do anything for the sealed lubricant.

JuiceSC said is the the truth---- why no mention of rust sneaking out past the o-rings--
it's there to see with your own eyeballs-- replace the chain right then and no cost of sprockets and labor......................................... sheez gang been riding too long to feed you crap info........

(semi @ Sep. 17 2007,05:05) i don't remember the figures at the moment but you measure from center of pin to center of pin for a certain number of links...when it reaches a certain length, the chain needs to be replaced...hopefully, someone will come along with the specs on this

OK, if you insist  

thanks bro

You guys wouldn't believe what my 1971 H1 did to chains. There was no such thing as an "O-ring" chain back in the late 70's.

If you think that sprocket in the first post looks bad, I've rounded off all the teeth with that 500 tripple.
