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 🤔

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???

They're like 5 bucks from Aliexpress

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

Looks like it is still lugs with carbon tubes. Maybe a new iteration? (From Jordan Williams' IG)

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.

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

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.  

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.

Have they worked out how to offer OEM service kits yet?

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.

wasn‘t jordan also late on the lugged proto? loic and finn were already on the proto while jordan was riding the old alu demo. maybe there is/are only 1 or 2 of this new demo available now. or jordan could be riding what he knows for now after coming back from injury.

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.

You are aware of people are running 600g cassettes these days,right? And dh casing tires on double blue flow trails lol

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.

Some of you are way too sensitive. Different sized cassettes are good options for different people and different riding terrain. Not everyone needs a big wide range cassette all the time.

Haha that hits right home 😄

If they managed to make it resist the extreme pressures that Asa must have put though that shock, my respects to Fox. 

I highly doubt that they didn't have to rebuild the thing every two runs, though. But one can dream...

Whatcha mean Chaz, doesn’t everyone live in Squamish? 

For places where climbs and descents are less than a minute long(most places on earth) modern tractor pulling gearing seems a little… off.

I wish more bikes(looking at you Fuel EX Gen 6) could fit bigger chainrings so we could make better use of the wide range casettes.

I totally get the idea of what these are supposed to do but even they admit it's not a true damper. https://www.rimpactmtb.com/tmd

It seems to be just springs with no damper on the unit so it's a shake weight, any momentum in the weight "smoothing" the trail has an equal or greater opposite effect, right? It's basically a Canyon KIS but for a different purpose or a fork/shock with the damper removed... aka a pogo stick. 

Not hating, just trying to read through the marketing.

the KIS was more similar to a Hopey steering damper in that in provides resistance to turning and in the case of the KIS, help it recenter.  

The TMD is a free floating mass that helps dampen certain frequencies by oscillating between the two springs.

Spec also lists Evol LV which likely reflects the larger air can shape.

Yep. It's a shakeweight.

A weight (or "mass") on a piston that can damp the intensity of the oscillations ("shakes") of the structure to which it's attached. That damping can be tuned to target certain frequencies of oscillations.

That Wikipedia article Primoz mentioned is really informative. Here it is again:

I think it's actually used more to lower the swinging of the skyscraper because of wind loading. But yeah, the most widespread use is in skyscrapers.
