Interesting take on the long-travel trail bike. The more nimble angles will be a boon for those of us who ride rugged terrain and a lot of tech climbs but don't approach speeds much over 30mph on our local rides' descents. Good to see a toned down edit with fun riding - the initial drop in on that slab looks sketchyyyyy.

Funny story: When I saw the Jeffsy 27.5 release, I thought it would be like this...which it is not.
Kona gets it. The move to expand the "super aggro enduro race beast for the consumer" has been a little misguided in my opinion, as most people would be perfectly well-off with a general issue 140-150mm, 67 +/- HA bike with proper reach and stack. Looking through the geo chart on this bike, I can't help but smile to myself, because this is actually what they've done. Rad.
Also, this was 100% the video I needed to see today; Dark mood averted.

...that tire looks like it'd be pretty damn awesome.

It's like in Alpine ski racing when a skier can feel the difference in 1 or .5 degree change in their edge camber.
Minnaar is legendarily fastidious with his setups, from tire psi to suspension, just ask Jordi Cortez. Brandon Semenuk too, with bike geo - there's a story about how he said something was 'off' with a brand new build, SRAM tech measured it, and the fork was 5mm too low.
Tire pressure is no different as Spomer points out, as it will be the same on a relative scale when testing under consistent conditions. Niki Lauda, the great F1 driver was just as meticulous with his cars. When people are the top competitors in their sport, it's because they can not only perform better, but also because they are in tune with themselves and their equipment in ways a lot of us can't/won't understand.
The commentary was solidly on point!

That's pretty wild that Gwin is knowledgeable enough about tires to basically mock this up on a napkin and have it come to life in nearly the original form. I've always thought tire design was a really overlooked aspect of the industry, and the more I learn, the more I marvel at it!
Update: 36lbs or 16.86kgs
Bear in mind I weight between 215-218lbs or ~98kgs, so to me, this doesn't matter.
Inertia is your friend when riding, and I've got alllll of it! hahaha

Whoever says, "Yeah, but air is lighter..." doesn't get it. Coil just works better (more consistently as Curtis said) and is more reliable. This is wicked. How about a 27.5 non-plus guys?

It's interesting to see/hear the difference in riding styles at these events. Aggy's, Sorge's, Vink's, and Makken's were all unpresidently huge, but then they come out to Dark Fest which is like a super-sized DJ set (versus the more "traditional" freeride monster gaps which look more like backcountry ski/snowboard booters) and they are totally blown away with it. I think it's so cool that there is even such strong variance among this group of riders.
This did not disappoint!

If Mad Max had a DH bike - rad!

This is so impressive on so many levels.

Spot on. I'll have to look for that. If it comes to mind and you have the time, it'd be really cool/helpful to see a close up photo of the set up. I'm going to do the same thing, I'm just trying to figure out how it all goes together.
*Edit: found the article with the photos. Helps a bit!

Encouraging to hear that! I was hoping this was the case. Being snowed in here in the North East hasn't been conducive for actually getting to experience this bike properly. I was only writing about initial impressions, and I am thrill to hear from someone with time on the bike that what I describe was of little to no concern out on the trail. Hope you're shredding a few extra corners for us still surrounded by snow!
Bear with me, I'm no engineer, but this is my best understanding of it and I added in links to youtube explanations from that rad engineering guy:
The single chain line (no cassette) means that the suspension is never affected by the gear selection (the "My bike feels better chainless effect I alluded to in my write up). This addresses the "anti squat" principle of suspension design. Coupled with a lighter rear end [no cassette or derailleur], the unsprung mass is reduced, meaning the force it takes to move the wheel out of the way/engage the shock is less, thus making it more sensitive to the undulating terrain i.e. the rear end tracks the ground better.
The really interesting piece of design has to do with the "instant center" of the bike, and how it remains incredibly central through the progression of the travel. I cannot explain that well though, as Rob explained it to be only one (in amazing detail), and I don't want to incorrectly address it, so here is this instead. You're correct in saying that it's a single pivot, based on the relationship of the axle to the main pivot, but link driven single pivot bikes can have a host of characteristics built into them via the links and their placements. I hope that helps, and if someone has something to add or correct, go for it - it's Monday and I'm in the clouds after being away for the weekend.
There is a plan to do just that actually - stay tuned!
I have no idea. If I weigh it, I'll let you know. My best guess is 34-35lbs. I weight a lot though and have no issue with pushing a bigger bike, and it helps that the 12spd gearbox has a ridiculously easy high gear...you could climb a wall with it. Stay tuned!
I mulled this over one day. Having zero engineering background or anything remotely akin to design prowess, I'll say this: I think it can be done, but because of how much wire is spooled in the grip shift (and thus the distance the wire needs to travel per shift), the problem may have more to do with the size of theoretical shifter. Just a guess. If Pinion makes one, I'll be one of the first in line for it. With that said, I don't mind the grift shift, and I'm curious to see how it all shakes down on the trail.
Perhaps so, I'll be hard to miss!
I think candor is important around this subject, as the gearbox isn't a "cure-all", but rather as you pointed out a different approach to a drivetrain to meet a different set of rider requirements.
