So, checked my crank this morning as its one of the affected codes, as per video on Youtube. All " seemed" ok.
So what do I do now. Take it to my local Shimano dealer for a confirmation check? Just ride it and ignore? What happens if I have a problem in, say, 2 years time?
How long will Shimano warrant these affected cranks?
I'd recommend getting it changed as soon as possible. It looks like the recall isn't for the UK yet, so maybe check with your local Shimano dealer to see if they can do something. If they're not helpful, I'd be inclined to replace it first and then try to do a warranty replacement with Shimano and if that doesn't work, wait for the recall.
In theory, you could continue using it if you check it periodically for any visible cracks or any creaking noises, but it's annoying trying to ride a bike with bits that you don't trust.
Not sure, the statement indicates the recall is across the EU region so should include the uk.
As to warranty, none of these parts are in warranty; instead we're relying on latent defect claims.
Given the failure mode the inspections will need to continue on any at risk cranks for their life, so what to do if your crank starts to debond in another year or 5?
It may be the only safe solution is to replace, but then are we sure the issue doesn't persist on new cranks? Without any root cause from Shimano it's all conjecture...
SF - bought in March 2021 post lockdown.
Without a fundamental design change, I'm not certain I entirely trust it to be fault-free but no signs yet.
My FC-6800 which did expire went to the tip after sitting on the side for a year, so I think I'm owed £240 that I can't realistically reclaim, for some reason I can find photographs of sausages and other important nonsense at that time but not of the crank. Post-lockdown it was just a case of even being able to source a replacement at all - this was a reasonable price from High on Bikes via eBay. No point trying to get from Madison via a dealer as they were drained of stock then and nothing was coming through.
My drive-side crank separated along the arm, basically the outer C of the D shape split from the inner straight bit, there is a seam on the inside of the crank. First symptoms were a bottom bracket-like creak.
As I currently have a seat but might be rear bearing creak, having a potential nother source of creaks is a continual irritation. Fortunately, I decided effort wasn't for me some time ago so I don't tend to ride hard out of the saddle.
My FC-R8000 looks to be new enough with code 'TA'.
I wonder what's caused the u-turn from denying that there's an issue to a recall a few years later? Reputational damage, maybe?
Basically the US "Consumer Product Safety Commission" forced them to. The US CPSC has statutory powers to make rules on safety and require manufacturers to recall dangerous products - though manufacturers will "voluntarily" recall products before it gets that far, when the CPSC makes noises to them, it appears - nearly all recalls the CPSC coordiantes are "voluntary". See Shimanos' statement:
https://bike.shimano.com/en-US/information/customer-services/recalls-and...
And the CPSCs' record:
https://www.cpsc.gov/Recalls/2023/Shimano-Recalls-Cranksets-for-Bicycles...
Tl;dr: Shimano strenously denied any issue, until the CPSC got involved, and now suddenly Shimano are "voluntarily" recalling the cranks.
Bugger! or hooray! I'm not sure which at the moment. Separation anxiety finally recognised.
(Has anyone got code OK?)
Looks like you're one of the guilty men! I'm guessing this is just a visual inspection, so if you can't see anything wrong, they probably can't. Shimano should put out pictures of what 'bonding separation' looks like.
