More gears. More gear range. stiffer crank arms. The combined weight of cranks and bottom bracket is lighter. More powerful rim brakes. More ergonomic brake hoods/levers. Shorter shift throw. More modern styling.
Not top of the line today, but better than the old stuff nonetheless.
The person I was originally posting to before some folks became sidetracked was asking for suggestions of compatible forged cranksets to replace their R8000 or R9100 arms with.
I stand by my recommendations of R7000 or Rotor 24mm options.

Well, aside from branding, if a lot of Shimano crank users that are not under recall (yet), want to replace their current cranks, I'm sure Shimano won't mind them paying them more money for another of their cranks. So, you could consider making a statement of sorts and instead purchase any other brand of crank as a replacement.

Pretty much ... my Ultergra 6800 cranks are seemingly fine, and from what I have seen and read it seems that they just don't explode ... some sort of impact causes the failure. I will keep an eye ion things but for now ... great cranks, decent weight, great shifting .... a few thousand failures in more than three quarters of a million cranks for whatever the math is ... i feel okay.

Why are some newer date codes and the newest models not included in the recall? I do not know. Perhaps at some point Shimano made changes to the assembly procedure and/or the adhesive itself that more effectively prevent water from entering or forming inside of the right side arm on Ultegra and both arms on Dura-Ace cranks.
It is advisable to regularly inspect your crank for visual signs of impending failure.

I don't think very many of the failures of the cranks are due to impact. Newer cranks are sealed better. Shimano announced it not that long ago.

As these cranks get older, the risk of failure can only go up.

I thought the number was 4000 out of 760,000 cranks .... as to whether they were warranty reports, I have no idea .... nor do es anyone else who is posting here, I think.
I wonder if the semi-viral (within the bike community) spreading of the broken-crank website played a part?

I must say though that I can understand that someone with an unaffected R8000 or 9100 crankset might still be feeling a little uneasy.

and as they go out of warranty Shimano's detection of failures goes down. this could make things seem better than they are.

A UK bike shop put up a video on how they inspect the crankarms and how Shimano is involved and compensates them -
.
My 2017 Ultegra crankset passed, did come back very clean!

I do a lot of big group rides and events where these cranks are commonplace. About half my riding friends have them on their bikes. But I've never seen or heard of a single failure outside of the internet. I'm not surprised the US was first to see a formal recall, given the "sue" culture. I'm sure it won't be long before the UK follows suit.

Now you can't sell the affected cranks on ebay.

I was a bit curious as to how this is to work at the shop end. It seems like its a "remove, clean, and look at it" process. Many shop owners I know are a bit older and have terrible eyesight, I don't see this as a final "solution." A less subjective process would be preferred.
This seems to be the official inspection instructions. Not very sophisticated IMO.

Why not? Because eBay doesn't allow the sale of recalled items.
I've only skimmed this thread, but am a bit surprised that a few posters are dismissive of Shimano's actions -- pointing out that only a very small percentage of cranks have failed, implying that Shimano has capitulated to a litigious culture. It seems very weird to criticize a large company for standing behind a product, no matter their reason.

^One interpretation .... I see it more as Shimano doesn't need to do much about these cranks .... even if they fail it would be really hard to prove they caused a crash and then caused injury ... which would be the only basis for a big law suit ... (except for class-action lawsuits, where lawyers get rich and plaintiffs get ... a new crank which they could have anyway .... )
I see this as Shimano walking the line between legal exposure and useless overspending. Basically, if you ever doubt your Ultegra or DA crank, bring it in for an inspection and get a replacement. I don't see anywhere where once you get it inspected, you can never again ... in fact in the video the bike repair guy says if your crank ever creaks, bring it back in.
Seems to me Shimano is taking the rational course here. Fix or replace what is broken, and since it is not likely a crash-causing failure and is actually very rare .... no need to recall every single crank.

On some other forum, someone posted a screenshot indicating that eBay rejected their listing of an affected crankset. (I'd link to it, but don't feel like googling it.)
