Dura-Ace R9200

It's hard to say where Shimano put the offset. But it's easy to tell if one has both the 9100 and 9200 rings (or 8000 and 8100). Just put them side by side and lay them flat on a table, and inspect the relative height difference of the teeth.

Regarding your -19 trim offset issue, it it possible that somehow your crank's chainline was messed up during the crank's installation? To check it take a measurement of the distance from the crank arm to the seat tube on both sides. Make sure they are the same. The BB installation could also affect the chainline. The 9200 crank and FD sits 1mm further outboard from the 9100. But the FD has already accounted for the +1mm increase in chainline so the trim offset should be 0 if the crank is positioned correctly relative to the centerline of the seat tube and that the FD mounting tab is in the correct position.

If you still have the 9150 FD (or any Shimano FD) you can swap out the conical washer from the 9150. They are the same.

this is where i got it

and truth is that moving the chainline out made a difference.

There are two different changes being discussed. A +1mm chainline and a -2mm chainring gap. Either one or both could affect shifting quality. I'm glad the +1 chainline made a difference.

Two new wireless modules were approved by the FCC in Dec. 2021. One for the shift levers and one for a RD. New Di2 105, GRX, or XTR? The confidentiality window for product photos and block diagrams ends in May. This implies another new semi-wireless group to be introduced prior to June.

Yes . If you go to https://fccid.io/WY7 you can actually sign up for updates via email, which is pretty cool

Any idea if GRX 12s or 105 are coming this year?

[ooo]

shimano is using "i-spec" integration for current mtb levers,
upcoming wireless shifter is called "dual control lever",
I am still not sure which group it is (road/gravel/mtb/gravity)

st-r9270/st-r8170 uses single coin-type lithium battery DC 3.0V
new wireless "dual control lever" is 6.0V - dual coin-type battery?
rear battery is the same bt-dn300 according to fcc

Thanks! I'm now subscribed. Would you happen to know the grantee ID for Campagnolo?

I looked, but I couldn't find anything

M9250 should be XTR, and usually it and Dura-Ace are refreshed close together. I wonder if we'll see more cogs?

As for GRX and 105, who knows given COVID? I'd assume GRX ought to be a priority given the popularity of gravel + competition from SRAM and Ekar but wouldn't be surprised if it has to wait until 2023 given current problems.

I would be surprised to see more cogs. The 12s Di2 is still missing in action, so the M9250 might be only the electronic version of the 12s mechanical XTR.

I am wondering about the GRX. The version now is based on Tiagra/105/Ultegra/XT, isn't it? Only Ultegra and XT are refreshed to 12s. So basically the basis for GRX 4XX, 6XX and 810 mechanical is missing at the moment (which is most of the market). My guess would be that the GRX refresh comes last. Or maybe they are only refreshing 810 Di2 and 812 mech/Di2 to conquer SRAM for the moment. But yeah, Covid is not helping. So my guess is 2023 as well.

'Conquer SRAM' in consumer gravel? That ain't happening any time soon. They're so far behind.

But GRX would seem like the lowest hanging fruit. Especially as they've virtually ceded high end full MTB groupsets to SRAM. Though Shimano are of course very interested in e-MTB ... so could be wrong.

More likely this relates to an E-bike product rather than XTR, GRX or 105. Might also explain the 6v power too.
