Surely they have tooled up ready for the recall and parts replacement plus here in the uk madison paying your local shimano service centre . It sounds like a local bike shop perfect storm .

You get 11 speed rings on 12 spd arms apparently

Bloody hell

The cranks don't last long once they start coming apart and they're only replacing the ones that are already coming apart so it will actually be not that many.

About fucking time.

I didn't realise it was a problem with older 6800 / 9000 series.

I can only assume this statement is to limit the numbers sent to them?
If they get sent a set don’t replace them and they then subsequently fail, aren’t Shimano in a worse position?

What is the 'dealer' you bring these to if you haven't bought directly from a retailer?

i'm guessing any shimano approved service centre?

I’m assuming any bike shop that has Madison on their books.

I've got a set that's in-scope :(

I had a 6800 pair separate a few years back. Annoyingly during a warm up lap of a CX race. They do creak a bit first before going so I got some warning but would never run shimano cranks since

I dropped my broken ones in at muswell hill bikes three years ago and never heard anything meaningful back about them (didn't actually buy them there so was in a nomansland for pushing them about it), got to be worth a follow up now! 😂

This is the problem I had though, MHB were doing me a favour by sending them off for me (got them on my Fairlight from Swift Cycles which then closed), and then chased til I lost the will to live and gave up and never got a replacement... Hopefully a different story now 😊

it looks like the recall just involves taking your bike in for a visual inspection, and if nothing looks wrong then you don't get a replacement.
doesn't feel very confidence inspiring...
worth keeping an eye on and getting some feedback from shop mechanics when they've been briefed.

This is what confuses me about this whole thing. If my crank has a failure I'm probably not going to know that it has failed until it really fails. So it is good now that they at least recognize there are issues with these cranks and in theory will continue to support/deal with them, but the whole thing leaves a lot to be desired.

Like, my cranks are apparently "fine to ride" as they don't have any cracks in them....but I'm also supposed to pay a lot more attention to see if they do start to crack. Doesn't inspire confidence!

isn't this just the same as the regular recommended maintenance for other components such as brake pads though?
have a look at them once a month to make sure they're not worn out, that sort of thing?

i get your point though. is this how other product recalls work?

in fact, shimano have previous on crank recalls -
https://bike.shimano.com/en-US/information/customer-services/recalls-and-repairs/fc-ct90-m920-mc12-cranks.html

Consumers should check their bicycles' crank assemblies. If they are involved in this recall, consumers should stop using their bicycles immediately and call Shimano at 800-353-4719 to arrange for the free replacement and installation of a new crank assembly at a nearby authorized repair shop. Consumers can also arrange for the free replacement with their bicycle dealers.

Leaked image of the 'free replacement'

brake pads / other wear items make sense to check regularly as they are wear items. Cranks? I mean, if you ride 30,000 miles/year I guess they are "wear items" that need checked regularly, but even in that scenario you probably wouldn't check more than seasonally / yearly unless something was noticeably wrong - and in this case, when things go wrong they seem to go wrong quickly!

I guess their math supports their inbetween response as they reported a failure rate of "only" about 0.6% in the US market fwiw. But given the nature of the failure it isn't confidence inspiring and your link highlights the shallowness of this argument. If shimano actually thinks these cranks are dangerous and worthy of a recall then they should tell people to stop riding them.

Not once have I considered a crank a 'wear item' that needs checking lol. It's a chunk of metal that is supposed to take serious abuse.

It sounds to me like damage limitation with not replacing them all.

Would I feel comfortable going full gas on a crankset that has a known issue for cracking? Nope.

There's the intangible element of brand trust if they held their hands up and said "ANY cranks in this generation, bring them in for a new set, cracked or not"

I actually wouldn't buy shimano cranks for this issue, meaning I wouldn't buy any other parts of their groupsets.

It's just not possible. They'd go bankrupt trying to replace them. There are millions of sets out there.

They should've investigated it years ago. Even with sales down 40% they’re still ending up with around £500,000,000 in operating profit and over the pandemic this was almost £1b. Just say what it is, greed. This is why they didn’t do this sooner and it’s also why they have put in piss poor measures.
