travsi, the owner is on this forum. Ask him about his experience.

Replace "install chain" with any maintenance on any item and ask the question again. There are a few steps in chain installation, namely making sure the pin is equally through on either side if you're not using a quick link, that can be and are quite often messed up. Hell, most people don't even know what a chain tool is.

NJS Chains.

Dutret chalks everything up to user error.

Incorrect installation:
push a pin in that wasn't meant to be pushed back in
push pins in and out too frequently
not push a pin all the way through the opposite plate.
push a pit too far though the opposite plate.
do something else that causes a stiff link
not install a masterlink correctly
not check a screw on masterlink frequently enough
etc

Things that can damage your chain:
chain suck
forcible derailment
shifting under force
rust
smacking it on things
etc

Deathare: I realize you weren't asking why chains break but with a few examples of very poorly designed ones or the infrequent manufacturing flaw they simply don't break unless you do something bad to them and that is dependent on you not the chain.

Because with chains and cranks the user(more accurately the maintainer) is responsible for the vast majority of failures not the qualities of any specific model.

thanksyou

I run izumi esh's on two of my bikes, one with the special link, and one without. I haven't had trouble with either, and yeah, whether it's justified or not, I feel more confident running these chains on my brakeless bikes.

I was thinking it was a truncated "BACALLIN"

That's right. It's what I like.

izumi V ! last for life.

i have been running on either an izumi esh or hkk vertex for the last two and a half years and have never once had a chain break or get thrown. i have broken and rebroken both chains several times (almost every time i change the gearing, i like getting my rear wheel in as far as i can). I measure them occasionally (every 2 months or so) to check for stretch and have been quite impressed with how well they have held up. I use the bolt masterlink, and feel secure riding up and down the hills around here. im a fan of njs chains.

The 1G8 is such a pretty chain.

Hang around here long enough and you will too.

I've been around here but left because dutret wouldn't.
