Thanks for posting this. Looks like the shifter hoods are slightly less aggressively shaped? FD doesn't have the same low-profile shaping as 12s DA and Ultegra, more similar to 105 and 11s Di2. RD looks very similar to 11s GRX Di2. Calipers I'm sure are the same as 12s mechanical. Overall what I would call a low effort groupset revision, similar to 105 Di2. Easier for production and lower on costs.

Any idea if individual components will be available? I'm building a new bike soon and will only need levers and mechs.

Maybe around 2-3 months, last year this shop can buy 12s Grx mech 60 days earlier before Shimano officially release it.

Yes, that's why it should be GRX7170. But GRX8XX used to be Ultegra Level. No sincerity for Shimano this time.

In a bit over a month we should have the details - no need to get too stroppy before we know what's what. However, if it works as well and the price is lower that will suit me fine!

From what I understand there won't even be any auxiliary buttons on the hoods this time. And hoods indeed look like they lost their awesome shape.

I'd call this a downgrade over 81x Di2. Stock up whilst you can.

I would be shocked if the price was lower. My pessimistic self sees this as a heavier, more expensive, low effort release that fits with Shimano's poor post-COVID financial outlook coupled with a constant need to churn out new product.

Might be difficult - here in Oz there's almost nothing 11 speed in stock. We do seem to be the lowest priority for pretty much everything Shimano, though surprisingly most of the 12 speed GRX is now available.

If that is the case I'll stay with the older generation. The buttons is an awesome feature on DI2 - Especially during gravel races with navigation where I often need to switch between screens on the headunit.

The current 11s is also performing great so not really an issue for now. But would be sad not having the buttons on the next bike.

The patent diagram shows them - and usually it's what launches. But the contact I had who saw them in the flesh said there was no button ... but maybe he was expecting it on the top instead of the side per the diagram, and missed it.

But re: pricing or this being a general downgrade, I think it almost has to be. Shimano are getting eaten alive by Apex AXS / Rival AXS in gravel and allroad. And I can't see them doing 2 SKUs given how much inventory of other stuff they now seem to have (lots).

This isn't a serious problem. Just run the Ultegra (or dura ace!) shifters.

This photo suggests it will be "shimano approved" for 11-36 cassette. Which in turn would normally mean, under standard Shimano operating proceedure, that it could run 11-38 or even 11-40.
The current ultegra is rated for 11-34 and for mountain riding I'm easily running the 11-36 pictured.
