I didn't downvote you, but the primary reason this increase in stack height is not great because it changes the fit the bike for the rider.  As @TEAMROBOT showed in the comparison of the two bikes - the 32'er has almost no drop between saddle and bar and the 29'er has a ton.

If the 32" wheel takes off, it'll kick-start the development of bikes with 32" specific geo, but for now, as a launching off point and to familiarise riders with the new platform they're basically borrowing geo from 29ers. I've no doubt that when testing on the wheel size itself is done, the next step will be to test changes in geo.

Have you ridden one? Sounds either no, or just think that multilinks is better regardless ( it’s not )

You kind of answered yourself in your question when you said, “I know lower stack means more power to the pedals.” In XC racing, getting more power to the pedals is almost the entire ball game. Aerodynamics is way less important than in road racing, so the main benefit of a lower stack height and more hunched over body position in XC racing is the kinesthetically optimized position for mashing the pedals. Easier to mash the pedals when you’re bunched up in a little ball. 

I never knew this.

Try one of those fan bikes in a fitness with a roadie-esque handlebar. It's really strange how "nice" it feels to be in the drops (lower) when mashing the pedals. There must really be something with the lower bars more power thing.

The simplified version is that being more bent at the waist means more quad, glute, and hamstring engagement while pedaling.

I'm almost certain that the new Maxxis tire will be the Minnion DHF2... I got a Test Pilote here in Andorra and it says Minnion DHF 2

... maybe to be released soon? Picture is the same as the original DHF currently. Rolling speed/traction/cornering graph thing is updated compared to the DHF.

More bent forward mostly means more hip extensors preload, and any good athlete generates most power from hips (glutes).

that's a worn DHR2 IMO 🤔

that potential DHF2 on jackson's bike has the L-shaped knobs turned 180 degree, like on vee tires.

It's just a more visible light connected to Flight Attendant so the athletes can tell what setting they are in more easily.  First ones were actually too bright and this version could be more muted.

Hopefully new analog treck fuel x gets long Chainstays as will.

Geo looks very nice, except 485 mm reach is too long for my preference

Could it be a steering angle sensor or electronic rotary damper? Either could be useful for the flight attendant algorithm.

Isn't it just a bigger led for flight attendant, so that they know whether it's soft or firm for when they use override mode?

This is getting down voted, and maybe it's controversial, but I kind of agree with it. I don't think a trail bike necessarily needs long chainstays or a head angle below 64⁰. That's what your all mountain or enduro bike is for. It's not like conservative geo on bikes is dangerous or un-rideable.

If you buy a good set of carbon wheels with lifetime warranty you do typically hold onto them over multiple bikes.. it’s what makes them cost effective.

You must never ever place a lego block not according to the instructions 😳

I've got a Fugitive with 5500 miles on it... great bike. No reason for it to be Superboost, but it obviously wasn't a deal breaker for me when I bought it.

Now I've got my super boosted Knolly, my boosted Stooge, my Moonlander with a 197, and a cargo bike with a good old 135. I recently sold my Chamois Hagar with a 142 rear end. 5 bikes with 5 rear hub standards. Some justified, some not.

Paying for a re dish and some problem solvers is not the end of the world, but I do understand, worst thing it’s a new rear hub and some spokes

Can’t speak for anyone else, but I usually buy frames and swap parts over as I like all my parts. Superboost wouldn’t be a full on dealbreaker for me, but it makes it more of a hassle than it needs to be. It seems like an all-downside situation to me, so why do it

Only mad dogs and Englishmen would tear apart a perfectly good rear wheel to re-use only the rim.

Here’s an interesting factoid/hot take. A very proficient  mechanic friend of mine runs Superboost hubs on all his standard boost bikes. Specifically Norcos. The wheel just pops right in there.

I would never do this, and I constantly raise an eyebrow at his set up. He’s been doing it for years and hasn’t noticed any ill side effects. Every drivetrain he’s used, including Transmission hasn’t reared any ugly shifting side effects, nor has he noticed any premature bearing wear or binding issues. 

He prefers Superboost because to him, it builds a stronger wheel. He would have never tried it, except he was coming off a Devinci and didn’t want to build a new rear wheel.

Crazy right?

I've run a boost hub in a non boost frame by just jamming it in there and buying a new thru axle. It worked great until the chainstay cracked. It worked long enough that I got what I wanted from the frame and then some, so no regrets, but i absolutely wouldn't recommend it. I think it lasted about a season before the crack was halfway around the inside of the chainstay where it was welded to the yoke.

I'd do it again, but only if it was another frame I didn't care about, and if it was a carbon rear end with a short-link suspension design so there is no cyclic internal stress from any misaligned pivots. Might make it OK. Probably not super boost though, that's a big increase in width.
