IMO its unlikely a failure will cause accident or injury and I'd keep riding it until it was a problem if it were me, unless it was clearly indicated as one of the bad ones by the markings.

IANAL, but it would appear that by not going full-hog, they've also opened themselves to liabilities by knowing that things could be unsafe yet still not doing the minimum required for safety (e.g. at least a set of periodic checks, though replacement might be cheaper in the long-run).

So much for Shimano's stellar warranty system. "If the local bike shops OKs it, ride it until you need a dentist". Nice. I don't ride those cranks, but you better believe if I had some and the local bike shop said they wouldn't be replaced, I'd buy something else and install it asap. You can play the numbers game all you want, to the people that had them fail, it's a 100% rate.

Shimano recalls 760,000 Hollowtech road cranks due to 4,519 incidents of ‘separation or delamination.....

From all the readings, seems the catastrophic fails were the 'I wondered why it was creaking cases'

Anyone else gleam that?
Yes, agreed, any creaking from the crank/BB area needs to be checked right away!

Defective spring design in XT and XTR shifters causes the downshift lever to completely fail, permanently. Shimano warrantied three of them in a row for me before I got sick of the routine.

I believe they’ve quietly fixed the issue but never admitted it.

As for the cranks, never forget 2019-2023 THANKSSHIMANO https://instagram.com/thanksshimano

I think what happens first is the glue cracks, which may be difficult to see since it's in a seam. It then develops into a crack of the metal, which is easier to see once it gets large enough to kill you. Hth.

And this goes for the chainsets too I'd say. The fact that I have R8000 cranks marked UK 'NOT' being on the recall list speaks to that.

I still wonder looking at some Pacenti V1 SL23 rims up on the wall I'd never sell just how many products skim under the radar. I have used them for myself with a washer schemata after several trials.

I make the point as unlike the cranks rims wear out faster outta there service life, yada. Is this how products like the V1 SL23 skate ultimately? How many other cycling products skate?

After doing some more research on the recall...basically it sounds like the Cliff's Notes are:

If you have cranks that have the early stages of a failure condition, they'll be replaced.

If you have cranks that are in the batches that have been known to result in failures, but currently look OK, you are SOL.

Is that right?

This is from CyclingNews...

If you are in North America and believe 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.
So what if the cranks haven't been used enough for any delamination to occur?

Recalls are a legal distinction, lets face it. We have a Chevy Bolt, so ask me how I know.

So not to stray too far... I do wonder how state of other countries 'distinction' handles recalls on these. Would it not be per laws of country which consumer protection vary wildly?

No kidding. While back, when this all got in our threads here I bought a few R7000 chainsets. Starting to feel my actions actually more than satisfying my paranoia. I feel a lot better about the anal mismatch feelings about now....

Clearly, we must consider if this moves a Shimano groupos into the replace the chainsets sooner than later. Older units having been in used longest and in the environment longest considered beyond service life??

🤷

Nothing has indefinite service life, check your bike before riding, whether it's Shimano or Campy or SRAM.

6 injuries in 800k recalled seems to suggest it's not a catastrophic failure.
