- Received my replacement Ultegra crankset from the Shimano recall. I am pleasantly surprised with what I got!
Update: I have since learned that Shimano had stated that they will be replacing cranks with this 12spd crankset, but with special 11spd rings. Looks like you will be able to purchase these rings going forward. - บันเทิง

The replacement cranksets are 12-speed cranks with special 11-speed chainrings for them. That was stated in the inspection training modules for shop technicians. It is also in the printed materials that were published months ago. Your local shop should have told you about that.
I don’t recall them mentioning what they are replacing the cranks with in the S-Tec videos as they were focused on the inspection process (but I could be wrong on that). Though yes, I went through the documents they have on the B2B and they do mention what they are replacing the cranks with.
the unit u got is made for 11s. distance between chainrings are same as 8000/6800/7000/5800/9000/9100@@dorianmode4
@@mykles Yep! It’s a 12spd crank with special 11spd rings that have the 11spd ramps.
I`m pretty sure these replacement cranksets have just standard 12 speed chainrings mounted. Only difference is a 11 speed print on the chainring. Lots of people use the 12 speed fc-r8100 cranksets with 11 speed components and have no issue. 12 Speed chainrings seem to be fully backwards compatible.
11 speed chainrings are on your new 12 speed crankset.
Yeah I’m seeing that now, as someone else commented that Shimano has stated they are replacing cranks with the 12spd design but with specially designed 11spd rings. They also noted that you will be able to purchase these rings going forward.
I think I should have said crank, not crankset.
What if you had after market power put on the crank set. Will there be any Shimano will do to compensate for that?
@@steveo5200 Actually yes! If your crankset fails the inspection and needs to be submitted for the recall, you can submit your crankarm power meter and they will give you money to get a new power meter installed onto your new crankarm. Shimano does technically say that an 11spd left crankarm does not work with the new 12spd spindle, which the replacement has, so I do recommend submitting the powermeter.
I used on a ultegra 11-speed bike a 12-speed ultegra crankset with 12-speed rings and it shifts noticable better than the 11-speed.
It would be good to know if the shape of the chainrings at the contact point is the same between 11 and 12-speed. If it's so, i would use 12-speed chainrings on old 11-speed crankarms
I got the FC09 replacement crankset with ‘11speed’ chainrings but notice sloppy shifting between rings and notice that the chainring ramps are different from the original 11speed rings. So, yeah, you are probably right that they just shipped 12 speed rings with the cranks. Wonder if using 11speed chain will make shifting better.

On small chainring is printed 12s anyway, so bigger one may be just labeled 11s while it is 12s.
The small ring says 12 speed on my replacement, but 11 on the big, sure it does on Yours to?😊
Nice that you got chsin rings. i just had to buy a new large chainring, for my ultegra r8000 is black
I’m very happy about that… I actually needed new chainrings for the crank that needed recalled. So it worked out well for me.
Great info!
Thanks! Very glad to help and pass on what I know!
It was stated in the original recall announcement that they'd be replacing with 12 speed cranks. No surprise there
Interesting! You are the first person I have come across that knew that. Must have been an easy detail to miss then.
That is a full blooded 12s cankset. The plastic cover inside the spindle is normal aswell, D.A and Ultegra 12s both get that
Thanks for confirming that! I have worked with bikes that have 12spd, but have yet to see a crank off a bike to notice if they have the plastic in the spindle.
I want to put together a bike Mechanical Ultegra R8000 11-speed. My question is about the callback. An original Dura Ace crank R9200 12-speed fits this group.
Is it really the exact same color than the FC-R8100 12sp cranks?
I had my 11-speed Dura-Ace crank inspected and it passed.... for now. The mere fact that could eventually corrode and fail drove me to just sell it. Purchased a Magene powermeter crank as a replacement.
Right, there is that big question mark. I’m sure you will be able to turn it in if it does fail in the future, but that’s assuming it doesn’t fail mid-ride 😬 Buying something else is not a bad option if you can swing it!
is the spacing between chainrings the same? that could be the only important difference
It is slightly different. That is why Shimano is using 11-Speed Rings on the replacement cranks.
He does cover this in the video
The 'new 11' Ultegra is definitely heavier than the old, probably from the reinforcing ..
It's probably as heavy as the (old) 105 , my R7000 compact 165mm weighs 710grams (entire crank with preload cap)
The right side crank (with rings) is lighter than the right side (with rings) of the 105 R7000, but only by 20g. I haven’t weighed the left sides, but can’t imagine there is much of a difference there since they are both solid cranks. But maybe I’ll throw them on my scale just to be sure. I think you’re right, though, the extra reinforcing they did for this new crank added some weight.
Right. So, you think the crank and Rings are 12 speed identical and it's just printing that reads 11 speed?
Not anymore. I have since learned that it is actually a 12spd crank with special 11spd rings designed to work with the 12spd crankset. I have updated that in the description for the video.
@@dorianmode4 I see, wow. Good on Shimano. This was not the recall program that they said they were going to do. People were saying they were going to give you whatever was available and tough luck to you. Seems like they changed that tune.
@@samuel8590 I agree. I think they are doing a better job than we were initially thinking. I also think they are going above and beyond to make sure their new cranks don’t fail again. Like I said in the video I wasn’t expecting new chainrings with the crank, and yet I get a whole new set AND the cranks would work with 12spd chainrings should I decide to upgrade. Thanks Shimano!
The 11 is on the chainring not the crank ?
The crank is definitely the new 12spd design, but apparently the chainrings are a special 11spd version that fits on the 12spd crank.
Hi sir, are you in North America? Can you tell me more about the process of getting it replaced and the timings of it? Thank you for the video
Yes I am in North America. First I made sure my crank was part of the recall. There is a list of production codes that are part of the recall. I actually checked out the crank myself first. When I cleaned it up, soapy water was coming out of the seams in the crank, so that alerted me to there being and issue. I took the crank to a bike shop, told/showed them the issues I saw. They confirmed it and submitted a claim for it. It took me around 2 weeks to get my new crank.
@@dorianmode4Seams in the crank?
@@michaelmappin4425 Yes. There is a seam that runs along the entire outline of the Hollowtech crank and spider (this is the right crank for Ultegra, and both right and left for Dura-Ace). You can easily see this seam, but it’s on the inward facing side of the crank. It is where the two halves of the crank are joined. These seams are where the failures can occur as they can de-bond/separate.
@@dorianmode4 Ok, I see it now. Thanks
thanks ! @@dorianmode4
How long did you wait for your new crankset?
It took about 2 weeks. I thought it was pretty fast… I was expecting longer for some reason.
@@dorianmode4 Thanks for the update. I had two Ultegra cranksets, both got send back by my local bike shop last week. Hopefully I can get my bike back with new updated crankset this week.
@@thejeffinvade Hopefully they come for you quick!
Is it normal for on side of the crank arm to be closer to the chain stay?
I would have to see it. Part of me wants to say that they should be evenly spaced, but maybe your frame is designed differently… like I know some gravel frames do different things with the chainstays.
It's a Fuji 3.0 2006 road frame. It does look like the non drive side chain stay is bent inward more than the drive side. Just curious. I just put a new crank arms on. I wish I would have looked at before I took the old crank off..
@@randy1817 that’s probably what it is, then. Some crank sets use spacers and so a lack of spacers could cause things to be uneven, but if we are talking Shimano, that wouldn’t be the case. Probably either a bent in chainstay, or a design they decided to go with.
It's an Origin8 crank. I not going to worry about it. I'm definitely not going to buy a new crank. Thanks for the input.
So shimano only replace the drive side and not the left side arm?
But the 11S and 12S color is different, isn't it?
You spent so much money on the crankset and/or Bicycle initially, and they hodge podge the replacement? They should give you a complete set.
Sorry for any confusion, but yes, they do give you a whole entire crankset. Left and right cranks with new chainrings. I was actually surprised by that. I figured I would just be getting a right crank arm, and have to put my old rings on. It is also the exact color and shape of the new 12spd stuff.
@@dorianmode4oh good. That is good of Shimano then.
Only the right arm on Ultegra cranksets gets inspected since Ultegra only has a bonded arm on the right side. Dura-Ace Cranks have two bonded arms, so both arms get inspected for Dura-Ace.
Any crankset effected by the recall that is found to have a failure on either arm will be replaced with a new complete crankset consisting of the latest 12-speed design arms coupled to "special 11-speed chainrings".
@@busterbrown2905 Good 😂😂 they willing sold faulty chainsets for years and denied any issues or calls for a recall! I would say the way they have handled this is far from “good” 🤦♂️
Good ol' Made in China Sh&tmano
There’s a lot of speculation in this video. Facts would be better. Measure the chainring gap, check the ramps on the chainrings.
Some speculation, yes, which was kinda the point of the video… that and a PSS to go get your cranks checked. There is no question that the crank itself is the 12spd design, but my question is if the rings were 12spd or 11spd. That question has been answered anyway as Shimano did apparently say it’s the 12spd crank with specially designed 11spd rings… which I had updated in the description of this video. I don’t have a real accurate way to measure tooth to tooth distance at home, but it does look like the inner distance from small ring to the start of the large ring ramps is the same as 11spd.
11 spd got different climbing ramps compared with 12 spd. I used a 12 spd chain on my r8000 groupset, but had problems to get the chain climbing from the small to large chainring. If the replacement crank is a 12 spd crank it should be able to use 12 spd chainrings and a 12 spd chain.
The r8100 got 52/36 as the largest chainrings and r8000 got 53/39.
When is the recall over?
Good question! I can’t seem to find an end date at this point.
Recalls never end, well unless the company ends. Recalls can change but never end unless proven safe and working as it should, which this is not
My crank came back as being "safe to use", but I replaced it with a 105-crank anyway. Not gonna participate in the "it is okay, really" game.
Fair! Doing that does avoid the whole situation entirely. Because there is always the question of “it’s fine now, but for how long?”
Has anyone in Europe received a replacement yet?
Yes. Got the exact same as him. 12s crankarms with 11s chainrings.
anything happened to you? or you just replaced working crankset?@@Timonius93
Please. Hollowtech is the name for the hollow Spindle with 24mm Diameter, not the hollow crankarm!
Hollowtech is also the crankarm, as shown on their website. Just search it up. Website says: "HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity."
Octolink cranks we’re hollowtech…
Hollowtech 2 is the 24mm spindle
11 speed and 12 speed chainrings use a different chain line - you are correct that they have made specific 11 speed chain rings.
The previous cranksets are not all faulty - only some and I suspect it’s due to a specific OEM supplied resin used in some batches…,
The issue was eradicated after 2019.
They did not have a recall because the data being provided by the dealer network only said small numbers - hence the inspection process rather than swapping all of them.
Most bike shops are seeing small numbers of failures.
Shimano has also said you can still get a replacement later on, even if it passes inspection today.
There are two serious issues. If it passes today, someone is unlikely to get reinspected. Failure down the line might cause serious injury. Secondly, if I want to sell it, the value is adversely affected by the recall code on the part. Buyers see it as defective regardless of what a bike shop says. Make that three issues. If the bike shop passes the crank and it later fails, resulting in injury, they are liable.
@@michaelmappin4425
I would think that anyone with a "passed" crankset would be inclined to look it over themselves more often afterwards, and bring it to the shop immediately at the first visual sign of an issue, or the first time there is a noise under pedal load.
If the bike owner has his cranks inspected and they pass, it is still up to him to regularly clean and check his cranks (as everybody should be regularly checking their frame, fork, rims, hubs, and yes crankset) for signs of possible impending failure, then bring it to the bike shop for a proper inspection if anything is suspected.
Racing gear is not indestructable.
Yes, there is something not perfect about the adhesive and/or the process used on many of the cranks in the effected batches, but not on all of them, and so far nearly every failed crank arm I have ever seen looked as if it had been thoroughly worn out already before it failed. Extremely worn out, filthy rings, grooves worn into the arms from shoes rubbing against the alloy, apparent bearing wear into the spindle from continuing to ride with a worn out bottom bracket, deep scars in the ends of the arms from striking the road, curbs, or who knows what with them. That sort of thing.
At some point, people have to be responsible for caring for and regularly safety checking their own gear before heading out on the road.
@@prestachuck2867 It sounds an awful lot like you're defending Shimano. My friend's crank failed in the first year he owned his new bike. Unfortunately for him, this was a few years ago while Shimano was still in denial. A Google image search for "failed Shimano crank" shows plenty of well worn cranks like you describe. However, I had no trouble finding newer looking ones too. I don't disagree that we should be inspecting our components. Shimano should be held massively responsible for a problem that they created and then tried to hide. It is the only component I've ever ridden in 40 years of cycling that I've had to worry about in this way. Mine looks almost brand new now, but what will my next 450 watt sprint bring?
cmon, they have been making disk brakes with faulty design, that enables easy grit ingress to a lever's internals, so you keep buying new brakes.
I used on a ultegra 11-speed bike a 12-speed ultegra crankset with 12-speed rings and it shifts noticable better than the 11-speed.
It would be good to know if the shape of the chainrings at the contact point is the same between 11 and 12-speed. If it's so, i would use 12-speed chainrings on old 11-speed crankarms.
It’s usually not a problem to use a higher speed crank with a smaller speed groupset, since the front derailleur just has to go a slightly shorter distance. It’s harder to go the other way around though. And all of this is much easier with mechanical shifting, but it could be hairier with Di2. I used to run an 11spd crankset with my 10spd groupset and it worked flawlessly.
@@dorianmode4As di2 overshoots and then goes back I think electronic shifting would be fine too
If you noticed an improvement, it is most likely because of replacing worn chainrings with new chainrings.
