If 11/36 is the best they have in terms of low gears, without going to the MTB cassettes and 1x, that's pretty shitty. They could easily do an 11/40 or 11/42 12s.

If not, it looks like GRX 11s will remain superior for 2x where range is needed.

Not sure I follow. If you're using 1x I can see the need for bigger than 42, but why would you need anything bigger than 11-36 with 2x?

I have limited movement in one ankle and have not needed lower than 30x36 on steep off-road tracks.

Would it be possible to combine GRX DI2 shifters with Ultegra 8100 or DA 9200? I would rather use those instead of Ultegra ST-R8170 and Dura-Ace ST-R9270 since the ergonomics of GRX are next level in my opinion.

Not until they have a 12 speed GRX Di2.

Yes of course, but that is surely coming considering the number of retailers that are already listing GRX 12 speed. It has been mentioned in this thread a few times now:

Anyway, just letting everyone know what is on my wish list :mrgreen:

It doesn't say "di2" anywhere on those
screenshots.
Looks like availability was reversed to reduce self-competition:
105 electronic first
GRX mechanical first

Good for you. But South East England - or England at all outside the Pennines - isn't exactly noted for its vertiginous relief, and there aren't *any* long climbs. That does not make it so of all other places.

Were I still living in the UK, you'd have a point. But I'm in the foothills of the Dolomites.

It was built with italy in mind. Climbs here are somewhat steeper & londer than in the UK and a little looser surfaced to boot.

Not everybody is carrying nothing or racing. When you're bikepacking and it's 25+% with water bars and eroded fire trails 30x36 is often not low enough. 26x42 or 28x44 or similar can be very useful, and even Jay Petervary used 46x30 + 11-42 to win the Tour Divide, and he's not a spinner. Racers (and ex-racers) consistently fail to understand that low gears can be useful to others, and this hasn't changed in the last 40+ years...

Because that’s quite a niche market. And you can always swap out a crankset for something with smaller gearing.

Yep, spot on. Hell, even in a hill climb race I've gotten use out of my "extremely low" 34f/40r gear and not only did I not finish last (I finished right around mid pack both for my age group and overall), but I overtook a few people who I could clearly see were struggling and grinding at a too low cadence. And this was a literal race, so if I was trying to do an endurance ride over that climb, I could certainly benefit from an even lower gear. So when I read posts on forums when random people try to declare things like "nobody needs a lower gear than X" without knowing anything about a person's fitness, preferred cadence, intended usage and terrain, I just laugh.

The attitude seems to be worse among club racers than people at the sharp end. A few people vying for places at big gravel races consistently use 50/34 and 11/42 or 11/40. If you look closely at photos you'll see quite a few SRoad 11-42 cassettes being run with standard compact road 2x chainsets. SRoad being popular as they're way lighter than XT 11/42, and for courses that demand it, it's better than XTR where the max is 11/40. I'm tempted to order one to try it. Same phenomenon on road ... club guys who barely ever see mountains will whine about big cassettes whilst pros and their teams plead with Shimano and SRAM for bigger cassettes so they can spin smaller gear - they were resistant for years as larger cassette range = more metal and more costly and time-consuming to make.

Still not conclusive that Shimano are introducing a new 12 speed freehub. Why would they? They have 12 speed cassettes in 10-45 & 10-51 already. Why introduce a whole raft of cassettes that require a new standard? Unless the top sprocket on the current MS doesn't line up in the same position as the road 12 speed? But bearing in mind how close they both are to the dropout, it's unlikely to be that.

This is far more likely to be DT main their wheels compatible rather than a new standard.
