Shimano crankset recall
Discussion
Something like 3 million affected. I guess the inspection (and replacement) won't be particularly quick. Checking your crankset yourself makes sense.

Certain ULTEGRA FC-6800, DURA-ACE FC-9000, ULTEGRA FC-R8000, DURA-ACE FC-R9100 and FC-R9100-P 11-Speed, details on the link.
I don't have one but as I'm building a bike in the next month, I'm tempted to buy the crankset in advance.

Good that they’re finally doing something about it but not much use to people like me whose cranksets failed ages ago and are now in the bin…
Agreed. I have had two Ultegra cranksets fail on me in the last few years. The first one I wasn’t sure if it was the result of a previous incident when I went down sideways on my bike so I just binned it and bought a replacement. But then the replacement also failed after about 2 years of normal usage. I did think about sending it back to Shimano for inspection, but that would probably have taken ages and I had to get another crankset anyhow to continue riding in the interim.I think you get a standard crank and a credit or refund of around £300 I think
I had a rummage and managed to find my old crank arm that debonded and an old chainring so I'm going to see if I can get a free replacement (I've already paid for a new crank set as it failed a few years ago).
Called my LBS earlier and they haven't had any official info from Shimano yet but asked me to email in with a few photos. It'll be interesting to see what they say as I only have the drive side crank arm as I sold the other side to recoup my costs when I bought the new crank set.

I had one go in 2018, I was heading to Rosedale Chimney at the time 
It was a good 90 minutes roll/pedal one side only back to base. Luckliy I hadn't got to the climb when I realised how bad it was.
Took a load of stroppy emails to get a replacement as it was outside the 2 yr warranty, but I wasn't going to be put off by Shimano. I think it was the UK distributor that actually sent the replacement.
The replacement went in 2022. Neither came apart totally, just a gap would appear on the downstroke. I thought my cleat was loose the first time. I ride through the winter on this bike and apparently the salt on the roads makes any potential problem worse.
I wouldn't buy Ultegra again, maybe not even Shimano. I found a 105 lightly used on Ebay for 50 quid, so we'll see if that lasts any longer. Some people say thay are the same construction, some say otherwise.

I think mine was 3 years old but low mileage and it was replaced for free without any fuss.
It was replaced with one that comes under the affected codes listed by Shimano so could be a problem too in the future.
The faulty crank just felt like a pedal wasn't screwed in properly when I got on the bike. Was OK on the previous ride.

You definitely need a new bike, that’s really out dated now.
Perfect timing - my DA 9100 crank gave way whilst out riding on Saturday. Annoyingly, despite the obvious failure, Shimano still need it to be inspected by one of their Service Centres, the nearest of which is 25 miles from me 
I'm off to Majorca next week, so need it resolved asap but can't see them having spares sat around...

Thanks for the heads up OP.
I've just had a look at mine and there is a noticeable gap where the crank is fixed to the chainring . . .
Thats what mine looks like as well. Don't really like the look of the replacement cranks so actually hoping it is OK.I've just had a look at mine and there is a noticeable gap where the crank is fixed to the chainring . . .
Dropped my de-bonded crank off yesterday, Mechanic in my local bike shop was a bit arsey to be honest.
I've purchased three bikes from them and as one of my Ultegra groupsets de-bonded after owning the bike for 4 years I sucked it up as wear and tear and purchased a new cranket.
When I noticed the recall I remembered I still had the faulty drive side crank (sold the non drive to pay towards the new crankset)and took that in, dont know if they'll accept just one side, if not I'll buy a non-drive side of ebay to make it a full set.
Mechanic said they've got 3 to replace so far and it could be up to 6 weeks. When I tried explain about the missing crank arm it was like I was asking him to dip in to his own pocket. Apparently I could have just got that faulty crank arm from anywhere?! I try to use my LBS where I can and have spent many ££££'s there but I wouldn't rush back with an attitude like that!

Yep.
It's not cheap to service a bike there and I would say up until recently it was the main bike shop in the area and they had everyone eating out of their hands.
It feels like a car main dealer, walk through the front door to the shop floor and you're greeted with a smile, visit the workshop and you're treated like a bad smell!

It won’t be 6 weeks, replacement cranks are in stock and will ship out as soon as the shops do the paperwork. You’ll get a 12 speed crank with reworked 11 speed rings, that willl be available aftermarket in the future for when you wear them out.I've purchased three bikes from them and as one of my Ultegra groupsets de-bonded after owning the bike for 4 years I sucked it up as wear and tear and purchased a new cranket.

Can people confirm whether I need to bother with this or not. My bike came with the Ultegra chainset that's effected, but I have Rotor arms fitted with a Power2Max power meter. I'm fairly sure I don't need to worry, but would prefer clarification. Here's a photo of the current set up:
Many thanks in advance
