Hi Guys,
Yesterday near the end of a 40 mile ride my DA9000 chain snapped causing a pretty catastrophic crash, which has resulted in some damage to my bike and quite a lot of damage to me.
The chain was less than 200 miles old.
My question is do I have any possible comeback with Shimano for the costs of the damage its caused?

Uphill struggle. You'd have to show that it was defective, rather than defective installation.Hi Guys,

Not sure if the damage to the rest of your bike would be considered too remote.
Any initial complaint would be to the vendor.0 -
I'm going to predict you have little chance.
Who fitted it?

Yeah, if you tell them they will just pay all the costs just like all the other chain manufacturers do.0 -
I fitted the chain but all I did was break it and fit a quick link, and it's broke about ten links away from where I touched it. I have no doubt the pin that's failed is defective.
Anyway, if there's no comeback then I'll leave it at that but I thought it was worth a ask.

Road biker goes to shop. This broke, compensate me.
MTBer goes to shop. This broke, what can I buy which won't break again?Advocate of disc brakes.0 -

Shimano chains are supposed to be fitted with a pin and not with a quick link, AFAIK. I appreciate it
broke somewhere else, but they will still hold it against you... why did you not fit it as Shimano advise?left the forum March 20230 -

Does anyone?0 -
aren't they all built by KMC? i just use quick links regardless and KMC chains. i have seen quite a few shimano own brand chains snap, far fewer kmc brand ones snap. that could just be me though.0

Agreed, and the only advice I've seen from Shimano is not to use a quicklink with DI2 (though again, who doesn't....)0 -

Hi, yes I am aware they would probably hold that against any potential claim, it's fine though I've accepted that there's no comeback, I only asked just in case there was some kind of provision for this I'm missing.One plays football, tennis or golf, one does not play at cycling0 -
Shimano's Dealer Manual clearly shows how to fit a quick link to their chains......

Any pics of the snapped chain ?
I'd certainly report it to them anyway.0 -

Would be worth reporting it to the retailer you bought it from. They may give you a replacement chain; Shimano did have a duff batch of Ultegra chains a few years ago so they may be interested to know.0 -
Actually I messaged the shop I bought it from earlier and they phoned me to discuss, the guy was very helpful and said if I sent the chain back to him he would push for Shimano to replace it under warranty, as suggested above he has said that they wouldn't cover anything else that was damaged but he was very enthusiastic about me sending it back to him, so kudos to them for being like that.One plays football, tennis or golf, one does not play at cycling0

I do, I have always done... I trust the Shimano pin, I don't trust the quick links, seen too many of them fail. I have never had a chain snappedleft the forum March 20230 -
Nor have I ...I have never had a chain snapped
I've seen two snapped this season - one required a push to the pub, the other fixed with my quick-link ... both were on bikes where the chain was a little past it's best ...0 -

Really? Really? I have heard of normal links failing plenty of times (broken two chains myself), but not a quick link...
Using your logic, maybe I should switch to a belt drive!- - - - - - - - - -

I've only once snapped a chain, but that was on a Chinese BSO I bought in a box from a bloke on a disused garage forecourt, so not entirely surprised.
I did have a quick link fall apart when the chain was marinading in a jam jar of white spirit. The pin and side plate just parted company; I think the dirt was holding it together. It is possible the link had been transferred to a new chain just once too often... :oops:0 -

I thought his contention was that in use the quick links somehow welded themselves together making removal impossible?0 -

It depended on the make, some were too tight and unable to be removed and others were too loose and he thought they would rattle about and undo themselves at any given moment!www.conjunctivitis.com - a site for sore eyes0 -

There is a reason every KMC chain comes with a new quick link.

I've never had a problem with Dura Ace 7900 chains with pin. After extensive testing, of numerous chains through their test rig machine, Tour magazine rated it the best chain available. The best chain when price is factored in was, and you can probably guess this, Shimano 105.0

The only snapped chains I've come across have been those used by riders who tend to cross-chain. I'm not saying the OP did this, but if you regularly bend a chain sideways it's quite plausible that it can be a factor that might limit its lifespan.
Whatever, I'd be p1ssed off if an expensive chain like a DA snapped so soon.0 -

Like the bloke i saw with a DA chainset on a sportif the other week - climbing a 3 mile hill - he was big sprocket and big ring. I asked him if he knew he was still in the big ring and he said it was the only way he knew to ride ?

It's on page 47, and it also clearly says that only 6/7/8 speed shimano chains are compatible with quick links (and yes - I use a quick link on 10 speed shimano chains too).Shimano's Dealer Manual clearly shows how to fit a quick link to their chains......

I snapped a 7901 chain on Swains last month. My own fault - I stood up to chase a clubmate on Bollard to Bollard, clicked up a couple of gears (Di2) and bang. Just because you can change gear under load, doesn't mean you should...
No quicklink, and it snapped a standard pin, not the joining pin.0
