Shimano Crankset Recall

Too bad the DA cranks aren't better looking than the 9000. Especially on my brushed Ti bike.

Can anyone clarify if the recall applies to nondrive side crank arms?
I just bought an SRM and the driveside of the DA9000 is propriety (I think just painted 7800) so they say it has nothing to do with the recall. What about the non drive side though? Is the bonding failing there or is it a spider specific issue?
thanks for anyone who can point me in the right direction

Dura Ace non-driveside arms can be affected.

what a PITA. I am debating taking it to a shop or just shipping it back on ebay. though some people's returns sound painless, I dont know if non drive side replacement will mess up the whole calibration of the SRM and have me hanging weights and doing calculations... Are any cranksets being replaced with "period" cranksets, or just newer models?

See this post from @BdaGhisallo upthread.

In short, the FC-SR70 crankarms shouldn’t be affected.

Toward the end, Shimano started manufacturing special 7800 cranks for SRM - they were labeled as FC-SR70 cranks by Shimano. These were the ones that were painted to look like FC-9000 DA cranksets with the two tone finish.

You probably have those SR70 cranks.

Shimano tired of providing cranks for SRM when they launched their 9000 powermeter and SRM had to look to alternate cranksets. It was around this time that they began developing their Origin crank chassis that most of their powermeters are built around now.

I do have that on the drive side, but the non drive looks like a regular 9000 crank arm and is coded with a recall affected "LJ"

Does the marking on your crankarm read "FC-SR70" or FC-9000?

Also mine has the code 0D, which I think is April 2016. Within the recall time frame, but I think the FC-SR70 marking on mine means that I should be a-okay.

All of the SRM Dura Ace powermeters are fine and use no glue in the construction of their crank arms. None of them were built with anything but 7800/SR70 hollow forged Shimano cranksets.

I bought the last DA9000 PM that SRM USA had for sale and it was still the SR70 crankset chassis.

Thanks for help. Drive side is the sr70 but oddly non drive was replaced with a regular 9000 arm, affected by recall. Not sure how this happened somewhere down the line. Unless someone had the regular crankset and the 9000 SRM upgrade and mixed and matched.

That mix and match must be what happened.

Best bet would be to source used arms, assuming you don't need something rare like 165 mm or 180 mm.

I would gladly trade my SRM FC-SR70 180s (or 175s or 172.5s) for 165s (or 167.5s or even 170s).

I got the last set of 165mm FC-SR70 cranks in existence when I bought my last DA9000.

I have a large doberman that guards my two DA9000 PM's when I am not riding them!

Your abode is also guarded by a big "moat".

Jest aside, I bought my 165 mm from SRM in fall 2019, sounds like you bought your right after?

I like everything about the unit except for the fact that battery swaps are rather expensive these days...

Good article by escapecollective, also mentioning this thread on it.
