It’s worth noting that from my experience as a mechanic working with a lot of these cranks and seeing a few fail, they will rarely ever show signs of bonding separating for a long period before failing. Once a bond starts to seperate or a crack forms, they fail straight away. These inspections won’t Really achieve too much in my opinion in terms of finding cranks before failure. This also raises the other important issue, once a crank is inspected a lot of people are going to think they are all good and not worry about it. What if as a mechanic I inspect the crank and say it is safe and then it fails in several months 🤷‍♀️

Great vid. Very thorough. I’m still in the opinion shimano should just replace anything falling within their suspected failure range. Like you said, thing could be a ticking time bomb.

If Shimano wanted some good will from customers, I would think that they could offer those whose cranks pass visual inspection the option of an upgrade to one of the replacement cranks at Shimano's actual cost. I'd part with $200 to know that I'm not riding around on a bomb that could explode underneath me at any moment. Just something I'd consider if I were in their position. If they get the old cranks back, I bet they could recycle the materials and even come out slightly ahead.

I'm a mechanic in a qualified Shimano shop. Biggest tip I can give you about all of this. If your 2 letters match with the ones affected, BRING YOUR BIKE INTO A SHOP. Qualified Shimano dealers have access to training to properly inspect the cranks. We can let you know if you're good to go or not (plus your cranks will get cleaned). A crank starting to fail "COULD" make a clicking sound and feel off, like it's sliding. Either way, check your cranks once a month, let the shop show you what to look for.

3:05 - Sound of Di2 gear change while changing scenes in this wide - so nice and cool idea! Great idea, Lama!=)

Thanks for the information. I find it extremely disappointing that your fellow KZfaq cycling/triathlon sites have still not mentioned the recall. Apparently a new software update to a sports watch is more worthy of acknowledgement. Anyway, thanks for thinking about us!

I do like the Di2 buzz for the slide transitions. Attention to detail 👍.

Its times like this I''m glad I'm poor and could only justify the more bulletproof 105 crankset 😂

A while back I had a Crank Brothers pedal spindle break on a trail and that was a very painful experience. As for a crank giving way on the roads, now that would be something I could do without. I guess I had better get my Ultergra 6800's checked out. Funny thing I had simply learned to live with the creak they often make. Thanks Shane for the update.

Make sure you check both cranks for the lot number. Mine have different lot numbers which surprised me, until I thought about how they are manufactured and packaged. My LBS mechanic congratulated me on being the first bike to come in with the affected cranks, but he wasn't sure yet what the inspection would involve.

I have had Ultegra one fail and snap close to the pedal end. So do get them checked! I'm with the opinion that they should all be replaced before someone is severely injured or a fatality! I managed to stay up right with the broken piece hanging off my cleated shoe!!

Thank you Shane for your time and efforts with all of this. It is greatly appreciated Sir.

Ahah! Love the crankset as bullet point indicator and the electronic shifting sound at slide change!

shimano managed to make the 12-speed cranks look even more wretched than the 11-speed models. now THAT'S impressive.

Spoke to my local shop today (UK based) and he said he will be advising all cranks to be replaced as he’s not happy to take the liability of “they are okay” if they are going to fail eventually. I suspect a few weeks if not less from now it will be a complete roll out replacement of all effected cranks from shimanos pocket

This is why I went with the 105 cranks on my, otherwise, full Ultegra build.

The fountain of all useful knowledge has once again spoken 🙌🏾✊🏾Thank you 👍🏾

Thank you for the concise and to the point information. I have an Ultegra FC-R8000 with TD, so I don't need a replacement, lucky me!

Good to see this being addressed, but take your point about a visual inspection feeling a bit "It hasn't failed (yet)" Rather than a definitive tick . Personally happy that I am on 105.

as the 105 user, I come here to observe...

Just to update people - dura ace cranks went in to the bike shop early october. Was checked on what i told was the first day they were allowed to start processing them - 16th of October. Received the FC-09 cranks back on the 3rd of Nov. This was in Canberra Australia. Cranks were bought while living in the USA.

I brought my bike with effected crankset to my LBS today. Got a phone call that mine was the first one they inspected that didn’t pass the test. Within 2-3 weeks it will be replaced by a new one. No problem, in the meantime it’s gravel time….❤ Ultegra FC-6800 175 mm

I've got a listed crank. I agree with comments below...Even if it passes visual "today", every ride after shouldn't feel like Russian Roulette! 🚑☠

When my 4th set of cranks failed, I threw them in the bin after Shimano Australia would not replace. I bought a set of Praxis! I will be following this up as I reported it to NSW Fair Trading

I have to say that some may deliberately force a delamination to begin just to get the upgrade......

As a mechanic, I would NOT be comfortable sending a customer back out on an affected crank which has passed inspection. If the crank fails in a week's time, say, who is liable? Am I or my shop liable for not seeing a hairline fracture at the time? The whole process is terrible and I suspect we might see this evolve into a wholesale replacement across the board as retailers refuse to carry out inspections.

Love my campy chorus with no glued sheet metal 😊

I'd be surprised if the ACCC were happy for just a visual inspection to be done. Considering our fit for purpose laws in Australia. Shimano would be leaving themselves open for a massive lawsuit if a crankset was cleared, but then delamenated causing an accident.

Did you record a DI2 mech changing gears for scene transitions? That's awesome 😃

Respect for the crank bullet pointer

Not sure why not just replace the cranks, why wait till failure, or signs of failure, to replace. So if I crank hard on the road and have an immediate failure, I can take the risk of falling and rolling under a passing car? Replace them all

If I had any of these cranks, I'd insist on replacement. How can anyone confidently ride a crankset that supposedly doesn't have the problem these cranksets have? The day your crank shatters and causes you to crash IS NOT the day to learn there really was an issue after all.

Great info. Was looking to upgrade my drive train anyway, and I do have the affected cranks....will wait to see what happens in Australia.

Nice to get an Aussie take on this. Concise facts. Thank you Shane👍. Feel sorry for the bike shops who will be inundated soon.

Better late than never, I guess. I had an Ultegra 6800 crankset fail on me about two years ago. Thought something felt weird as I finished a ride and then noticed that the right-side crank had a big crack through it and was very close to splitting in two. Replaced at my own expense because it was out of warranty, despite seeing plenty of posts online showing that this was a common issue.

Thanks for this. Others just used this to make a quick video but only you addressed the main issues.

In the exact situation you mention at the end. Right crank has an affected manufacturing code, left crank has a power meter and is therefore newer and (apparently) unaffected. With regards to getting a new power meter factory installed on the replacement crank, this could mean we're without a ridable bike for a very long period of time. Reached out to my LBS here the UK, and they've told me today that there's going to be a Shimano video showing consumers how to do a first pass of an inspection and only if it fails that will we go to the shop, presumably for a more thorough inspection, which TBH I'm even less happy about. They did say they'd only want the cranks taking in, which makes sense if you've already taken them off anyway to do your own inspection. Finally, why are they replacing them with a Frankenstein* modified 12 speed crank set? I was under the impression that at least 11 speed R8000 was still being made, it's certainly still available to purchase in the UK. (* a Crankenstein?)

Question, if my crank passes inspection does Shimano take full responsibility if in the future my crank separates and I have an accident? I certainly hope so, if not then replace my crank!

It's not a recall. It's an extended warranty. Replacing only failed parts or parts that have visual defects is not a recall.

great coverage. Been following this disaster for years. It's a little too late for folks who had sudden failures and suffered injury as a result. I smell lots of time in Courts around the World with this one.

I am not feeling good about this at all. My 6800 isn't showing signs of delamination but after reading about how these things fail I don't feel 100% confident to put power down on a climb anymore. There are plenty of stories and pictures flying about where these things failed without warning... Shimano should pull the plug and replace all of them. I mean they already acknowledged there is a problem, this makes me even more uneasy :| A worldwide recall? Free inspection? This shows the problem is a lot more serious than we thought.

Great video Shane. Checked my Dura Ace 9000 and found a crack in the drive side, by the pedal. I use Absolute Black sub compact chain rings, so I doubt they will fit the replacement.

Good work Shane - Thank you

What I think is going to be most interesting, is how long they will keep the inspection/replacement program going for, as like you say, it may not be a problem Right Now, but it could still fail quite some time later. Heck, I still have some R9100 crankset components on the shelf (from upgrades to Stages, etc.), that's not going to have any signs of wear/failure, yet could be susceptible. It's a can of worms...

The video states that only the right side is affected for Ultegra @ 1:15 . I couldn't confirm this info anywhere else. If true, that would be great as single-side power meters are always on the left arm... Can anyone confirm?

A good question is what process change did they make, as some of the affected cranks continued to be made after the end date. I have a RF left side and RG drive side... looks like I just scrape through. I have a newer set with Tx numbers... again they look just the same though. In reality the only fool-proof way to know the affected cranks are ok would be to x-ray them... a process that would certainly exceed their value in labour and logistics.

I’ve got a failed RG coded crank that was fine till it went pop on a ride and I could see the centre crank spider flexing/moving outwards as you put force through the crank arm. RG spec isn’t on Shimano’s list! Now returned to Ribble for a warranty claim to be submitted as advised by Madison UK. So sadly the list of codes on the inspection programme doesn’t cover all the potential or already failed cranksets 🙄

I'm in the same situation 9:00 😂 going to my LBS today to get the right side inspected.

I’ve been told by an independent bike shop in the uk that shimano still haven’t agreed to compensate them for the cost of replacing the cranks. Who pays the mechanic? With potentially hundreds to change, that’s a significant amount of workshop time taken up.

Thank you Shane, very well explained!

As always quality video thanks!!

Great video. More helpful than anything Shimano has put out on the issue.

My Ultegra 8000 crank failed by cracking and delaminating, i felt the pedal was flexing before i noticed that the crank was faulty and only noticed the crack and delaminating by chance. Whilst trying to identify the fault It was during Covid so I couldn’t get a crank from Shimano UK but they did reimburse me fully for the purchase and fitting of a new set of cranks. My mates 105 crank from about 2019 also failed recently and looked like it had suffered corrosion within the BB, this happened without any warning on a short steep climb, luckily there was light traffic as he fell off the bike into the road. Shimano UK replaced free and free fitting with no quibbles. It is concerning that these cranks are apparently failing due to the hollow tech process and i wonder what would be the response should a “checked and not failed” crank later fail resulting in an injury or worse to a rider? What liability would fall on Shimano then?

I think they should all be replaced. Why should I keep an eye on it, if its known to be an issue and will eventually happen... and possibly happen before an issue is observed. Dangerous!

Shimano should replace all these cranksets. At minimum, they should offer to replace any potentially faulty crankset at cost and with installation. I am not happy. I now feel unsafe whenever riding my bike. I'm pretty sure I will replace my crankset with a non Hollowtech one and that my next bike will not be Shimano. And be sure to have an official inspection done, if only to cause Shimano some financial pain.

They will have to recall all the cranks no matter if its not delaminated, because they will get sued time and time again. They won't have a choice but to recall all the cranksets especially how the laws work in the States and UK.

My experience is that this recall is already a s#/t show. My Trek Emonda with Ultegra components was in the shop because I was having some creaky sound’s coming from what I assumed was the bottom bracket. Inspected by LBS and found a hairline crack in frame that Trek replaced under warranty. Trek got the frame to the shop in 2 business days. I told the shop about the recall on 9/22 they inspected and could not find any visual signs but shimano asked them to ship to them for further inspection. 9/27-28 shimano failed my crank and agreed to replace under the recall. Today I am told that estimated ship date is 10/30! With shipping and installation rime I am looking at 6 weeks to get my defective crank replaced and mine was turned into Shimano on day 3 of the recall. They knew this was coming and should be able to do better. Looks like SRAM will be on all my bikes going forward.

This recall is getting an F. In short: not a recall. It's legal cya after 4500 incidents. Parts are replaced only if imminent failure is obvious, which is really just extended warranty and hoping the crank does not fail after Inspection. For context, Peloton replaced +2M seat post a after only 35 failures (+250lbs riders were falling off stationary Bikes), which is what responsible corporations do. The shimano fiasco is way more serious.

Sounds like the inspection is one and done. What happens after the initial inspection?

thx for this. I was in scope (ie the model /batch numbers matched) for a bike purchased in 2016. Took into local bike shop and they found issue and have sent it back. The bike had recently started creaking ... So assuming the creaking is due to the issue , its taken approx 7 years and lots of heavy stress riding (90kg weight , do quite a lot of short / sharp hills). The bike shop showed me the issue on above , was showing on the inside of crank which was only visible after taking it apart I have another bike from 2020 that is in scope that i'm waiting to take in - no creaking - if it gets the all clear , i will have no confidence about riding on it. Not good. PS I'm in the UK

To make it even more muddy: How about Pioneer Powermeters, as this product is bought by Shimano? Will the warranty be the same as with a normal Shimano crank with Powermeter?

This situation gives anything but mental peace. I mean, what is the guarantee about my crankset not failing in the near future despite the mechanical inspection on my local retailer?

How long is a crankset supposed to last? I actually have never thought about this until you said 2012

My Ultegra set is included but by using a mobile phone camera's macro mode with led light, yielded no visible delamination or hairline cracks

Shane, I assume you inspected all your cranks. Did they pass according to the course you took?

Who pays the mechanic to look at it then? How do I go about compensation?

I’d been waiting your update and comment! Has there been any comment on if you’ve changed the chainrings to non-standard rings? I didn’t see anything in the FAQs. Example being I use FC6800’s, Stages left side but switched standard rings to a narrow-wide single ring (on an Alfie set up). Dealer replacement would be for the replacement cranks but I’d assume standard rings.

I wonder if they'll replace cranks that fall outside the years and models stated. FWIW, my ultegra is 2021 and have had no issues but you never know what will happen in the future.

The left crank of my Dura-Ace FC-9000 failed around the pedal thread area in early 2017 after several years use. I was overseas and had to replace it with something to get going again so managed to find an Ultegra FC6700 crankset. If they replace the crankset with FC-09 wondering do they also supply the chain rings as I think the FC-9000 ones would not be compatible?

The US site says to bring the bike in for inspection... would they also inspect a crankset that I've uninstalled myself? That would be way more convenient for me. Although at least from my visual inspection, they don't look to have debonded at all so it would be very interesting to see what constitutes a "visual inspection".

did the largest cycling channel GCN not get this news yet?

By having bike shops check the cranks, aren't Shimano shifting any future liabilities? If the crank breaks after being given the ok it could well land on the head of the bike technician and shop.

My Focus Paralane 2 has nearly all components from shimano but the crankset is FSA, does that mean i am out of the woods?

I hope mine can be recalled because I need to replace the chain rings anyway

Touché on the 'credit where credit's due.... literally' line. That's why I never go past a GPLama video 😂 onya Shane

Thanks for the info. I'm not happy with the different replacement idea. An R8000 with 4iiii power meter on the left and an fc-08 on the right... that's not going to look nice.

My FC-8600 has the "OK" code so looks like it will need to be inspected :( Nearest Shimano place is a 96km round trip and operate a booking system where you have to leave the bike for up to 10 hours from your appoitment time before collection so will be two trips to get it checked!

@gplama unfortunately KZfaq iOS app doesn’t show comments oldest first, just “Top” or newest. I don’t see any pinned comment either. Did you forget to pin it? Might be good to put a video-specific link to your website in the description in the future to handle this

funny but true story: one day before they announced the recall i bought an old Roubaix bike with 6800 cranks. One of the main reasons for the purchase was so that i can own 6800 cranks. I always wanted them. xD they are fine. No cracks. But the design of the back side shocked me. You can literally see the glue there. Bad engineering from Shimano. No wonder 6800 fail the most.

TG my Ultegra model is TG!

Is it just the cranks or chain rings as well that will be replaced?

I have owned 2 of the effected cranks. A Dura-ace 9000 and a Ultegra 6800. BOTH have failed! That is a 100% failure rate. The first in 2017, which Shimano did nothing about. I bought a replacement for the Dura-ace 9000 left crank arm that failed. I used the Dura-ace 9000 crank until 2000 until I no long felt safe with it and I installed the Ultegra 6800. And when the 6800 started separating, I replaced it before it broke, so it didn't kill me. I never reported it to Shimano because I knew they would do nothing about it. Now that the recall is official, the number of reported failures is going to soar! Far beyond the 4519 they say they are aware of. But I think they have waited to issue the recall for over 4 years, when they knew there was a big problem, because a lot of those affected cranks have already failed, been thrown in the trash, and replaced already. And now, no longer available for inspection. So Shimano is off the hook. Very sleezy in my opinion.

I have a crank with one of the affected codes, but it's now running a wolftooth chainring. Using 3rd party rings is going to void warranty, right? Means I'll have to find a set of Shimano rings to put back on before talking to them.

I had a crank fail ages ago and got a replacement from Giant. I now have a Giant PowerPro front crank based on the R8000. I wonder what will happen with that?

I have two cranksets that fall in the affected category. What happens if an issue develops later on? What happens if the issue was not detected but the crank breaks anyway after a week? .

While I understand that Shimano is trying to minimize their losses, all of these cranksets should be replaced regardless. It's like Takata saying that out of the 67 million airbags recalled, it will only replace the ones that show signs of imminent failure...

Hmmm I have two bikes both with Pioneer dual PMs on affected cranks. Will Shimano make good on these if they fail inspection? After all Shimano bought Pioneer.

Shimano: "Your cranks need to be checked. Despite being checked out okay, they might still fragment in the future, but eh - that's yo problem" Also the "providing payment compensation" for crank power meters and not providing any sort of replacement while the cranks are back with shimano is pretty poor. I have two bikes affected by this with need for replacement still TBD

At the 6gap century ride this weekend I was talking a guy from Colorado who’s son Shimano hollow Tech 2 ultegra crank came apart during the ride on one of the climb’s he said that the support form the bike shop was able to replace the crankset so I guess they came prepared for this! I have the same crank on my madone I don’t feel comfortable riding knowing that the crank could snap at any time, visually check is not enough for this type of problem, even if you are doing a visual check and everything looks fine there is a lot of force being emitted onto these cranks I think to be safe they should just replace all of them!

hi shane, i have a giant power meter (2019 version) equipped shimano R8000 crankset which is subject to the recall. have you had the original (or replacement!!) cranks from your TCR inspected?? and how many giant pwer meter cranks have you been thru???

What coverage do you have if you've bought the bike 2nd hand and don't have receipts for bike or cranks? What paperwork does anybody need? Or is having a faulty crank enough? It's still dangerous, right?

if I remember correct you did have a 2019 TCR with Giants own PowerPro powermeter bonded to a FC-8000 Ultegra Crank right? How do you deal in a such case. Just curious - I have 2020 but the with the same Crank / RF revision. Tnx in advance for a short reply.

Got mine replaced by my retailer about a year ago when the creaking turned into a crack, immediately sold them on eBay and bought a nice Rotor replacement, won't be buying Shimano again any time soon.

All the failures photos that I’ve see posted on-line suggest that the failure occurs where the right hand crack spider joins the big chain ring. Are left side crank arms really affected by this recall?

Thanks. Has the inspection process begun in Australia?

Jesus. Cranks have to “show signs” of failing? This is not a true recall. I hope this goes class action and Shimano is bent over in the courts for waiting 11+ years for a half baked recall.

Who now wishes they had not chucked out their old broken cranks!

This is going to be so messy. I have 3 cranks all delaminated in the shop I work in all with customers who want a new crankset straight away.

My original local vendor is no longer around...no real alternative accessible...and yeah, I run a suspicious crankset 🙁...they should just replace the lot...I have no problem changing the cranks myself!...oh, well, hopefully I'm not affected🙁
