Focus on what's important here
The half skull gusset thing on the side of the headtube is in the running for coolest thing done with aluminum in a while.
If you're going non-dentist materials, gotta do some cool shit I guess.

Looks like YT is changing up the design of at least the Capra. Looks like...well, a lot of other bikes.

FFS, other than scaming moar money out of some hipster, I can't fathom why are these brands still working on steel. I get the whole steel is real mantra/dogma, but c'mon, with aluminum being so cheap, versatile and ductile I'm still amazed some asshats are still bragging about their uber heavy Columbus/Reynolds something something frames.
This precise case ultimately cements my beliefs, given they are resorting to aluminum for the rear triangle, as many other brands do.

Well, you´re not wrong there.
They´re apparently planning on releasing a second version with a two-part fully machined main triangle. So this is most likely just a way to get some early funding and/or cash in on the hipster crowd as well.
Not a stupid strategy for a super small company for which the main selling point is exclusivity.

I guess the issue here is if they can source the material, fabricate and weld it. Steel is fairly easy to source in smaller quantities and more people can weld it. Aluminium is easy to source and cheap in Asia, but in Europe it is hard to source tubing in smaller quantities. Then there is the issue of heat treating if you buy 6000 series aluminium from Asia, which not many have the possibility to do. Therefore 7000 series aluminium is more common in Europe, e.g. that is what Nicolai uses. In a recent podcast they said that they have to buy a 2 years worth of supply of tubes at once to get over the minimum order volume though. So as a small startup I would say that unless you hook up with a company that is already producing aluminium frames then there is no chance to get the material needed. Blocks of aluminium on the other hand are easier to source, also in smaller quantities.
After all it might be just a thing of what is possible for them. If the hipsters love it, even better.
Yeah it’s interesting seeing the steel is real trend come back around. It seems to be mostly coming out of the UK these days.
seems to me it’s a bit of a backlash to how sorted, but also kinda homogenous, mainstream MTBs are.
I’ve always liked the looks of steel and currently have a cheapo steel hardcore hardtail... but I won’t kid myself that steel is the optimum material for a contemporary MTB.
Jeez there is a lot of Ti going around these days again too in some scenes.

Me likey! any more data about it?
Sherpa Cycles from NZ. all i got right now.
NZ loves it's gear boxes...It looks great though, really dig.
yea they do. it sorta reminds me of the forbidden druid as well.
What is that high-tech wizardry holding the pulley in place there?

also, how is the swingarm not aligned with the center of the cog? and wtf is up with the other random holes nearby? and, shit, zoom in. weirdness EVERYWHERE. is it just a bizarre photoshop? or joke? what the hell?

Uber heavy? There is no mention of weight in that article.
Have you actually compared the weight of a well sorted modern steel frame vs aluminum?
For reference a Cotic RocketMax is 3.85 kg. A GX level build coming in at 15.34kg. An aluminum Transition Sentinel GX is listed at 15.31kg on their website.

I think the steel thing is more on the real small boutique bike brands. You want to sell like 1-200 frames a year? Steel is probably the only material that makes sense. Aluminum is only going to end up lighter in an MTB if its hydroformed, while I've seen people hydroform by plasma cutting out the shape they want in 2 sheets, welding them together and hooking up a pressure washer to it, but thats not a production manufacture method for sure. And the machinery for doing it for real is quite expensive, you can probably order pre-formed tubes but that gets you into ordering from china, big lots, long lead times. Heat treating isn't that hard, at least in the states, Bodycote will do it.
Carbon is another option for the smaller guys it at least kind of make sense cost wise at those low volumes, but there's the health risks, environmental concerns, and modeling it to figure out how to make a bike thats light and isn't going to break is harder than steel. You also have the warranty concerns with carbon, both as the company being worried you'll go out of business if you have a defect/design flaw and have to replace half your frames, and from the customer perspective, do you really want to buy a carbon frame that might need to be warrantied from a company with questionable solvency. That just doesn't cross your mind as a consumer when buying steel.
And now all the carbon and Al bikes look pretty samy from 20 feet away, a steel full suspension bike stands out even from far away.
Have to say props to him. Definitely looked like a one-off. Think this kinda thing is cool and interesting. Reminds me a bit of bcd back in the day.
Agreed. Looking at the finish on the carbon it's definitely not pretty, who knows about production worthy. But as a one off its cool as hell. Would never turn down an opportunity to ride it.

I hope instead of a resume he just sent them the bike. Not being snarky here, that is a major accomplishment.
A Sneak Peek at The New Eminent Onset MT - Pond Beaver 2020 - Pinkbike
Eminent's latest has 155mm of travel and 29" wheels.
I kinda liked their high pivot w/ idler design a few years back.

want real bad, don't want the weight though.

Because steel is the shit.
Flexing rear triangle on a fairly long travel bike is interesting. I am not saying it can't work and hopefully Swarf gathered some valuable experience from their Contour frame
