Current Gen XTR/XT/SLX all have a 10-45 Hyperglide+ 12 speed cassette option since their launch. It's also the same cassette that are used for current mechanical GRX 12 speed 1x with medium cage derailleur.

Great to have this option

Only a vertical wall climb requires a 51t on an e bike. And on my hardtail, which mostly just is used for shorter trail rides, I run a 11-42 and rarely use the 42. Some of us would rather a tight spread than wide range  

BITD I ran a 11-32 with a 34 up front and never had any issues. Kids these days 🤔

As I say to everybody with a view like yours, come to Slovenia. We have a few climbs here where it's likely you'll be wishing for a 28t ring up front to replace the 30t on your bike to pair up with that wide range, 50+ tooth cassette out back. 

There are some people that can push insane gear ratios everywhere, but they are far an in between. There are different terrains around the world requiring different approaches. But overall, for most people, wide range cassettes are a benefit, not a negative. Having more options is great, but catering to a small percentage (a loud percentage, but still small) is something few companies will do... 

The new Classified 10-40 cassette gives you 570 range I think ;-)

Says 530 % on their site. Looks like you get an effectively 10-53T cassette with very fine gear jumps and quite a bit more complexity (parts, shifting methods, etc.).

I would love a Classified system (and is an option where I would like electronic shifting) if the cassette was 6spd 10-14-18-24-32-44 with a Classified-esque system filling in the gaps. So not to offset the whole cassette, but to actually use each cog of the cassette for 2 gears. And do it via a single remote.

That's where they need to go for wide spread acceptance. If they can reduce the largest cog and go with a short derailleur cage, all the better.

I would guess its not so much of a "flip chip" rather then different slugs that can be used to to fine tune position.Something like the photo below.

Technically any slug that is not centred is also a flip chip 🙂

Classified hubs?  Nah.

I am testing one on a road bike, even in that application the extra weight on the rear wheel throws off handling enough for me to not be interested in the product.   Adding all that  extra mass at your rear axle?  No thanks.

Saw the new upcoming turbo levo out in the trail today. Passed by me so just enough visual to know it was a turbo levo and with no upper crossbar by the shock. Can’t say much else or specialized might take my post down 

Is it safe to say that you thought you saw a Levo SL but then realized it looked like a higher-calorie version of an SL?

The rightmost one in the image turns your Trek into a Yeti.

Instead of the Classified system, we need to ressurect the Hammerschmidt. Refine that system, get it lighter, 2x instead of 1.6x overdrive, and now you can run a DH rear cassette-shifter on your enduro bike.

I had that idea too some month ago to use the Hammerschmidt and a GX DH on my enduro bike but the gears were overlaping. And the Range wasn‘t that Great. But I would buy a Hammerschmidt with 1:2.

I take it you don't have or ride very steep long climbs around your area. I'm currently running a rear 52T cog with a front 22T chainring. I'd love a 60T cog so I could run a bigger chainring.

I call BS, who even sells 22t chainrings? And how many chains do you get through???

There's actually lot's of 22t chainrings out there.

They're like 5 bucks from Aliexpress

Not that I see the point for a 22t FOR MY RIDING, but still

22-52? At that point you need chalk mate as that's rock climbing not cycling.

No. You'll reach the largest cog, shift the Hammerschmidt and be forced to move across the cassette. There's a reason I said you'd have to pair a Classified-esque system with a 6spd 10-42t cassette. While Classified and Hammerschmidt were devised to replace 2x front rings, their shifting performance is anything like a front derailleur system. You should be using it all the time, not some of the time and be throwing the chain from one end of the cassette to the other while shifting the front too.

Its mostly tongue in cheek, I think either product is pointless with modern wide range cassettes. 

However, if you find the need for one, it makes no sense to put the overdrive in the hub when you can instead put it in the crankshaft, unless you want BOTH to get a 4 speed transmission!

Side note, Id ride a 4 speed cassette if it could shift, I have no need for all the other. 52, 40, 25-30ish and 10/9.

Brand new open bath technology. Comes with the air already mixed with oil in a patented "OIR" blend so you don't need to worry about pesky seals and stuff.
