Another slack chain question

http://www.sheldonbrown.com/brandt/chain-care.html

Riders often speak of "chain stretch" a technically misleading and incorrect term. Chains do not stretch, in the dictionary sense, by elongating the metal by tension. Chains lengthen because their hinge pins and sleeves wear. Chain wear is caused almost exclusively by road grit that enters the chain when it is oiled. Grit adheres to the outside of chains in the ugly black stuff that can get on ones leg, but external grime has little functional effect, being on the outside where it does the chain no harm.

hippy - raising tensions since 2007.

hippy - tensioning raisins since 2007

Murtle stretching chains since '85

I fooled you all!!
hippy runs his chain quite slackly.

I suspect this is the dumbest and most pointless argument on the internet.

during this thread has anybody actually got an old chain and a new chain to compare length, side by side? wheres mitre tester?

jesus, have you even read this thread? the debate is not over whether chains get longer. everyone agrees they do. the debate is over the reasons.

some allege the link plates actually get longer due to the chain tension - this would be a chain stretching.

some allege the chain gets longer due to the cumlative effect of each pin wearing away at the link - effectively increasing the pitch and elongating the chain, not stretching it.

the first of these two is a myth and a misunderstanding. the second is correct.

Thread ends.... restated

oh, and mitre_tester is now mdcc_tester and...

The myth is that any chains stretch at all. They get longer due to wear of the pins and the holes in the inner plates in which the pins rotate.

They stretch. Ask gagz

FFFFFFFFFFFFFFFFFFFFFFFFFFUUUUUUUUUUUUUUUUUUuuuuuuuuuuuuuuuuu....

:D

I need a new shirt. The old one has stretched. See?

According to this website, chains do stretch.

you lot are a bunch of pissy whinging c*nts, the phrase strech covers what happens amply, they get longer, who cares why and what does it matter, the fact is they get longer.

hehe. cheers Ed.

Ed is a good man. I've always said this.

Sound as a pound.
