Maybe trying to meet a weight goal? At this point it feels like some of these production "enduro" wheels are more suited to the trailbike market than they are bigger bikes. 

That price too, ouch. $1600, why would anyone buy these over WAO at that cost? 

I totally agree, I have a set of WAO Unions that are still perfectly straight after 2 seasons of riding, and I prefer the steeper tech trails. Also just ordered a set of the convergence wheels w/hydra hubs for $1263 out the door with their march madness sale. The Raceface wheels looks nice but don't see any reasons to move from WAO especially for the price difference. I would imagine most people buying these wheels are probably buying them for their strength/lifetime warranty moreso than trying to shave grams off their bike build.

Anybody spot on the wind rock race video what looks like flight attendants for a boxer on Lucas canyon?

I have a set on my enduro bike right now, but have only gotten one ride in before getting a seriously nasty bug that has kept me in bed for almost a week. That one ride was promising, very comfortable and a light feel. Will report back if they explode on me, but I am an average-at-best rider so I think it would take a big mistake on my part to destroy these. Really liking the compliance features and the engagement of the Vault hubs!

I have a set of AM30s with I9 1/1 hubs on my trail bike and Reserve HD30s on I9 Hydra's with inserts on this bike, I will likely use this wheelset for light, casual riding then swap back out to my Reserves when bike park season starts in a couple of months.

Finally, yes, I am fully aware that my bike looks like a circus attraction. Couldn't handle it anymore and grabbed some black Maven calipers.

I wouldn’t doubt it. Flight attendant would make a certain amount of sense on a DH course.

Everything Geo related is a compromise. Ride a different stem/bar/spacer setup 2 times and it doesn't feel "massively" different anymore. If it still feels bad after 2 rides, revert back and keep searching for the perfect mass produced frame that's absolutely tailor made for just you. 

The amount of whinging about brake modulation, tire carcass feel, and geo specs in this thread is ridiculous. 

1,000% of non-pro riders are holding the bike back from its true potential, not the other way around. At least Moto guys own it when they're an anal "Vet Rider," who can never stop tinkering. Over here, the bike is the problem, and it's definitely not "proggressive" enough, lol. JFC!

So incredibly true. I’m all for the excitement of  tinkering and bracketing to find out what works best for me but there is definitely a point where focusing on being a better rider will make you way faster than focusing on the mm’s of a frame or what new incremental changes are coming to X part. 
 

What sucks is when the opinions of people who have never ridden the thing they have an opinion on drive trends. Just look at the Pinkbike comments or even this forum to find self proclaimed engineers who apparently know what’s best vs the company that invested thousands of R&D to make the final product that you’re immediately sh*tting on the day it’s released. Click on their profile of these “experts” and you’ll find that they’re most often 35-50 yr old dads who think that the bike is holding them back.  
 

Puzzling is cool but people need to get outside more.

I’m pretty far from an anal rider.  I usually check my tire pressure with my thumbs.  Check shock pressure every two weeks.  Always a bit behind on suspension maintenance.  But geo is not something I can get around.  I found my Hightower seriouslu holding me back cause the reach was too short and the stand over was too high.  I paid stupid money for short cranks so I could comfortably ride my spire in the low setting since it was massively better for me though it’s realistically a few millimeters of difference.    I have drastically different reach/chainstay numbers on my hardtail, trailbike, and dh bike because I know how I want to ride them.  I am far from a talented bike rider but I know how to build a bike to comfortably push my limits and know how to build trails that work for/challenge all skill levels.

 

tldr. I’m only decent bike rider and my bikes aren’t mint condition but I’m perfectly capable of discerning between millimeters of geometry and how it effects my riding.

Does anyone know what Yeti plans to do with switch infinity link? Do they evolve on it in an even more unique fashion? I hope so personally. 
 

Also speaking of unique things, what ever came about Cannondale testing the 2 rear shock downhill bike?

So Yeti is a DW (suspension link designed by Dave Weagle) historical DW bikes don’t really change such as Ibis, Yeti, Evil. But recent years that hasn’t been 100% true. With Pivot changing their whole line up to a new platform with some of the same DW attributes. Or Devinci changing all their bikes to all 4 bar horst link.
 

TL;DR: maybe, but I wouldn’t count on it. I definitely wouldn’t count on it being anything other than a DWish platform.

The DH bike is a 6 bar. So that's something new at least. 

And they're XC bike is a flex pivot. 

So maybe they're not as tied to switch infinity as we once thought

Yeti is not and never has been DW. They did all sorts of different things (single pivots, rails, etc.) then went for the bearing executed Switch suspension, developed further to Switch Infinity which uses links. The e-bike and the DH bike use a 6-bar design that is not dissimilar to Switch Infinity in characteristics, called Sixfinity. The XC bike is a single pivot flex stay, as is normal for XC bikes these days... Looks like the suspension system is not worth as much as less weight is.

Devinci is Split Pivot (not Horst) like it has been for... How long now? Since Split Pivot has been made public by Dawe I guess.

Speaking of Sixfinity, this is what Yeti has at the bottom of the page:
"A TRUE SIX-BAR DESIGN. FRACTIONS OF A MILLIMETER DIFFERENCE IN THE LINKAGE LENGTHS AND PIVOT PLACEMENT IMPACTS ANTI-SQUAT AND ANTI-RISE CHARACTERISTICS. IT’S INCREDIBLY COMPLEX. IT TOOK A HALF DECADE TO REFINE THE SYSTEM. UNLIKE MANY OTHER “SIX-BAR DESIGNS” SIXFINITY USES ALL SIX LINKAGES TO CONTROL THE WHEEL PATH."

I fully believe fractions of a millimeter make a difference, but... I do wonder if companies with such sensitive suspension systems map out the behaviour through the tolerance range prescribed with the parts drawings. If a fraction of a millimeter influences characteristics, realistically with a (for example) +/-0,1 mm tolerance on centre to centre distances within a link or a frame you could have two completely different bikes in feel sitting next to each other in the shop painted and equipped to be 'the same bike'.

Just entertain the thought that maybe, just maybe, the bike is really holding the 35-50 y/o dads back, but in a different way than you might think. Most bikes are designed and developed for and with 25 +/- y/o, fit, incredibly skilled pro riders. That is not me and most others on here are not on that level as well. So that is why trying to emulate a setup that pro riders use and the bike industry sells as the cool new stuff to have might in reality be holding back the average rider. I am not saying this is always the case, there are good examples of improvements and products that the average Joe can benefit from. As you wrote, trying out what works best for you is the way to go. However, that also means that sometimes you can already see from the prodcut announcement that this product most likely will not be beneficial for the average rider, or, in the worst case, even be detrimental for their riding experience. So why not voice this opinion in the comments on forums that are meant to exchange opinions about mountain bike-related topics?

No but a few weeks ago he was running a Reverb AXS controller on his DH bike with no Reverb AXS installed

Trying out special, really really soft skis showed me what carving looks like with my shitty technique and finally sent me on the path to greatly improve my skills (incidentally also triggered the raising of my cockpit on the bike...). Trying out a WC slalom ski would not give the same results, that's for sure. So there is something in the right equipment for the right cause.

Speaking with some of their guys, they still think the SI is the best for that mid range up and down bike. But have have agreed that its weight is a negative for XC and its characteristics are not as crucial for a non pedal DH bike. I didn't get a straight answer on the Ebike but did hear it's hard to integrate with a motor, as they share the same space.

While SI isn't DW, they are damn close with that very small translation/ low link. They are trying to accomplish the same thing.

Wasn't the original DW link design or patent positioned in such a way where the lower link did not change direction of rotation? I seem to remember that the IC is supposed to be on the lower link at full compression, though that is still possible with a change of rotating direction. But I think recent designs have gotten more aggressive in the amount the lower link rotates backwards? 

But this is very similar to what Switch Infintiy and Sixfinity do - extend the chain length for antisquat early in the travel, make it shorter deep in the travel to prevent pedal kickback.

The best explanation of SI I've heard (or visualised) is that it's a "DW"/VPP/Dual link design, where the bottom link is infinitely long (since it can't rotate at all).  Which since it can't rotate, forces that oscillation in movement through the travel of the sliding part.

Road cycling has started to figure this out; most people won't be comfortable on a the bike a world tour rider rides so they've started offering bikes for normal (i.e. not world tour) riders.

There’s not much you can do to an XC bike and the DH bike isn’t on the market…

But I think you might be right.

All of these bikes were built on the back of the DW/Switch link. 

But I see what you're saying. I could have phrased it better mb.

That's exactly how sliders are evaluated kinematically, draw a perpendicular (infinitely long) line through the pivot on the slider carrier and see where it intersect with the line on the other link. That's how you get the IC.

It's literally like having an infinitely long link.

I wouldn’t doubt it. Flight attendant would make a certain amount of sense on a DH course. 

The main problem with electronic suspension in a human-powered vehicle is deterministic vs intelligent suspension; it may seem counter intuitive at first, but intelligent suspension, that makes "decisions" on its own, is actually worse for biking. If there was an electronic fork that adjusted the compression/rebound based on depth of travel, or shaft speed, that would be excellent. Position-sensitive damping is probably easier with electronics than a bunch of bypass ports, sleeves, and tubes. But this is "deterministic", given a set of conditions, it will always give the same output. This allows the rider to adjust the suspension, just like turning a knob, and then know how its going to react. "Intelligent" suspension, like what Fox and RS have, I think makes riding worse. The electronics is trying to decide when you're pedaling or not- no bueno. You don't know what the suspension is going to do in a given situation. Riding a bike is not something done with your brain, its done in your brain stem with reflexes. If you don't know in your brain stem what will happen when you do this or that, you're going to ride slower. A good analogy is if you had two people riding a bike at once, each person with one hand on one side of the handlebars. No bueno.

Can we finally do away with orange lowers on these new fox forks? One of the worst things to happen to mountain biking.

Forks with orange lowers and black lowers are the same cost, so what's your point?
