ooh; just checked mine, they qualify (they say OD on them)

Birka

I've two qualifying sets here but "The dealer will inspect the crankset for signs of bonding separation," Shimano's statement continues. "Consumers whose cranksets show signs of bonding separation during the inspection will be provided a free replacement crankset from Shimano that the dealer will professionally install. "

It's a bit tricky if they've been bought online....

On a slightly different note I am currently chasing Shimano through Madison UK for credit on a replacement crankset that i put on the bike to replace one that failed by way of a crack on the driveside crank. They tried to fob me off with the 2 year warranty but I kept at them, it's going on over a month but they back tracked this morning.....wonder why ?

secman

I need to check serial numbers on 3 bikes and also the one that's just been replaced.

Hehe, 'crank recall' - I thought you were talking about one of the mods!

did you get cranky with them?

Bambaata

About time they've acknowledged this. Been a known issue for years and actually made me deliberatley not buy Shimano cranks!! Stuck to Rotor since and will probably only eer get a Shimano one if its a ful bike purchase (which is less likely as it seems impossible to get a 54/55 tooth front ring from Shimano anymore! Seems their new 7100 is max 53!

hesker

So recall for inspection. Wonder what happens if the crank passes the inspection but then debonds in a year’s time

I have 2 affected cranks. Ultegra and DA

Drake66

The recall processs seems very sketchy. They will only replace it if it doesn't pass inspection but they encourage you to regularly inspect it in case it starts failing at some point in the future.

Bambaata

Guess they cant just recall everything or they'd be hit massively financially. Might they be trying to offsett some form of liability if one fails causing harm and owner couldnt prove they inspected it!

magicbastarder

760k units in northern america; at a replacement cost of say $100 each, that'd be $76m. and that's presuming they could make that many cranksets in a few months anyway.

Daroxtar

Are they going to replace my beautiful silver DA9000 crankset with a new one that looks like melted wellington?

Large bottle small glass

So cigarette box calculations.

"Assuming" Ireland has pro rata the same number of crank sets sold as USA and Canada there has been about 10000 sold here.

We have 15 authorised service centres, which equates to 666 per centre.

I think the evil swines are betting on most cranksets being already dumped/worn/ or on unused forgotten bikes. They are probably not wrong.

I'll like to see my indemnity in writing before I'd start inspecting any cranksets if I owned one of those shops.

Is there a type of use which makes failure more likely; I'd love to see a map of failure locations

monkeyslayer

Lovely timing. My 2017 ultegra crankset with approx 35,000kms 🙈 is long long over due replacing, hopefully can get a replacement this side of christmas. Still have my receipt and all.

magicbastarder

you need to go out and put some power down, they won't replace it unless they can detect delamination.

magicbastarder

i wonder if Mercian Pro will be back on to Madison - IIRC when his failed, because it was out of warranty, they sent him a replacement 105 one instead. does this mean they'll now issue a like-for-like retroactively? or will they consider those old reports as closed?

Daroxtar

The timing couldn't be more ridiculous, a clubmate just posted a pic of his crank that failed last night and asked if anyone had ever seen anything like it before

IIRC it's basically just caused by moisture getting into the compound that bonds the outer and inner part of the crank together; i remember positing on here that wet weather use could be linked to it, but someone (who claimed to know what they were talking about, can't remember who it was) suggested that it'd wick moisture from humid air anyway so cycling in the wet would not specifically be a factor.

That would be my biggest issue too. Saw this on another forum

Seems the replacement cranks are 12-speed versions modified for 11 speed.

They’ll have to take my DA9000 crank out of my cold dead hand to replace it with that yoke 😂

I don't think that's an issue, they're not saying you have to bring it back to the original dealer.

"If you have an affected crank, you are advised to immediately stop using it and contact a Shimano dealer or an authorised inspection centre (essentially any store that is familiar with Shimano components and has passed Shimano's maintenance course). The dealer will then perform an inspection, and where signs of delamination or separation are found, a free replacement will be issued."

triggermortis

My 6800 began to fail a couple of years ago so I replaced it with a 8000 series one. I'm sure I only threw it out recently when I moved, which is just my luck. It was definitely debonded as you could see the flex

magicbastarder

what's the difference between 11 and 12 speed at the crankset? i thought the internal width of the chain was the same?

JMcL

Is it only applicable to north America at the minute? Seems that way according to the Cycling Weekly story in the linked tweet, though it'll have to be global now they've admitted it's a problem.

https://www.boards.ie/discussion/comment/121140254#Comment_121140254

They say it's only cranks from before 2019, so you'd imagine more recent ones don't have the issue. Mine (R8000 2020/21 probably) doesn't feature in the list of codes. Also, if the graphic the @Mr. Cats posted is accurate, the replacements look like they "made from girders" as the old Iron Bru ads went

magicbastarder

this all started when shimano started making the cranksets (and groupsets) only available in black. i hope they learn their lesson on this. bring back silver groupsets.

monkeyslayer

There has been a wicked creak out of it over the years, for a long time I believed it was the frame. The solution eventually had been to spray the small gaps where the star shaped part of the crank meets the chainset with a tiny drop of tf2 lubricant after any sort of deep clean. But there's never been any sort of wear or deterioration visible to the eye anyway.

Is applicable in Europe also….

Humphries replaced mine at no cost to me after it failed even though it was out of warranty but I don't know if they took the hit for it or passed it on to Shimano.

ciarano

A scenario,

I have 5 affected cranksets i have many bikes so could be time before i know if they become faulty

say I bring to LBS for inspection and they pass

Are shimano seriously asking the LBS to inspect a crank on there behalf? after a recall

What happens if in a short while i have a dodgy crank and i get injured then the blame game would be the LBS ,

should a recall not be a recall in full ?especially when you match the effected part number

magicbastarder

you can be guaranteed that the LBS will not be held liable - no way would they take part if they had to assume a whisker of blame.

CrowdedHouse

Anyone know what the signs of a problem are?

I have an Ultegra 6800 on the list, I don't even know an LBS but I'd be fairly sure there's no one in my town to inspect it.

Bought direct from Canyon

Problems are related to signs of delamination or separation are found

Sweet. 3 cranks affected. FFS

Anyone have a previous issue due to this able to describe how they first noted it?

The Shimano video describes how to do the inspection yourself

I think it might have to be a Shimano Service Center, and they're thin on the ground depending on where you are. You can find them here https://dealerlocator-api-prod.shimano-eu.com/demo/shimanoservicecenter.com

Looks like they have made the video private

secman

Heard back from Madison UK this morning, they are giving me credit to cover retail cost of the chainset but not covering labour cost. Retail cost to me incl VAT was €278. Credit being arranged through my LBS .

Paddigol

Good luck to anyone trying to buy something with Campy on it... Shimano seem to have completely suffocated the market so that everything out their is offered with Shimano and the odd smattering of Sram. It's absolutely crazy.

Many thanks for that. I see there's one in Portlaoise, not too bad.

Seems like they have alright.

From memory there’s not much to it.

Pedal the bike and check for clicking noises.

Visually inspect where the spider mates to the chainrings and check for raised spider at the junction.

Check for signs of cracks or splitting anywhere on the crank arm or spider

For DA need to check non driveside also

Hi, what prompted you to contact Madison. Did you get from them directly or from a UK shop?

secman

Madison UK are the distributors for Ireland, I was like a dog with a bone as both themselves and LBS were fobbing me off.... well trying to.

crosstownk

I've a 6800 crankset that's concerned by the recall. Does anyone know what the 'signs of debonding' are? Or, even better, does anyone have access to the Shimano technical bulletin that's been issued to approved centres outlining the inspection process and failure criteria are? Although I'd be confident that such information would be strictly confidential.

EDIT: I just read @hesker comment above which is close enough to what I'm looking for.

magicbastarder

i saw the video the other day. basically it's pointing towards clearly visible signs of cracking or debonding. in short, if you can't see it, whoever officially inspects it won't see it either.

This appears to be their Dealer Manual to carry out inspections

Yep - that's why I'd sooner inspect it myself.

Thanks @jimm That's exactly what I was looking for.

this.lad

I have the Giant PowerPro. Read that if a crank with a fitted power meter fails they will replace it with a standard crank but won't replace the power meter.

They will, apparently, give a rebate towards the cost of a power meter.

Fighting Tao

Surely the EU will hop on this and direct a full recall. Failure has the potential to seriously injure people. Shimano that if something is ok now and they are washing their hands of future failure is dodgy as hell.

cletus

Is the recall time limited? if not, they might just be hoping to replace cranks as and when, rather than a bulk recall.

https://www.boards.ie/discussion/comment/121162379#Comment_121162379

I'm guessing that by the fact they are only checking for signs of failure they are trying to kick the can down the road a bit.
