Oh and this https://youtu.be/_OwRLKDRlDA
I do not understand how it differs from the Wolverine. I have a Wolverine and love it.
Can you explain the differences like a 10 year old could understand?
Been keeping this under my bonnet for a couple years, but they finally built up a prototype so here it is. It's basically a 650b Wolverine with dropouts from the Rohloff Saga Disc and an EBB/PF30. It's built with Tange Infinity so it should be soilidly in the budget price range, which to be honest is about the most I can really afford.

It's was designed around the 50mm Cazaderos, which obviously aren't available since they have yet to be produced.

Two sets of mid-seatstay rack bosses. Is there a (particular or generic) rack intended for these?
Can I request a tiny size?!?!? I need a ~500mm effective top tube, ~720 standover!The smallest wolverine is way too big, but this could be done with a 650b wheel!

I've rolled the 650b Cazadero and it's nice but it feels and looks like too much tread imo. I like the continuous center tread but maybe half the secondary ad shoulder knobs. Or something.
The other one - makes me frowny. But could well be dope.
Anything that needs much more tread than the latter (or a Thunder Burt) would typically be less stressful on a real MTB with flat bars, suspension, higher BB, etc.
As an aside, I sometimes wonder what Americans mean by "gravel" - does that just mean roads lacking bitumen? We have plenty of those here in Oz, but most are hard packed dirt +/- various contaminants, and are rarely surfaced with gravel as such.
Later,

Most Americans think of a gravel or dirt road as one that doesn't get traveled so doesn't need to be paved. But in the N.American west, Plains, and Prarie, there are many miles and whole districts of improved gravel roads intended for regular travel. These kinds of roads are where a lot of the recent gravel racing takes place and they do have that layer of failry uniform gravel. When newly surfaced, It can be sharp edged slidey stuff that I do not enjoy.
There are some western districts where you see improved gravel roads like this but also, depending on which county is maintaining, improved dirt roads, sometimes with an oiled dirt surface. Terminology still gets mixed but locals usually say dirt road, oiled road, and gravel road to distinguish. (I haven't seen oiled roads in a while in CO, maybe they aren't done any more?)
Another kind of gravel road in the US west is a regular paved surface road where every few years they put down wet tar and then a thick layer of gravel but without any tar sealer layer over the gravel layer. Over time and with vehicle travel the dry gravel is supposed to sink down into the tar layer underneath and eventually look like a regular paved road. That can take a while and in the meantime you're riding on loose gravel that gets less loose over time.
I've heard that process in the west is called macadam, or macadamized, named for the Scott inventor John McAdam. When Stephen refers to bitumen I understand it to be a tar sealed road Americans would call (~smooth) pavement(?). When a British person says pavement they mean what Americans call a sidewalk. So when Americans cycling in Britain hear someone yell "Oy! Get off the pavement!", they answer "that's why I'm riding on the sidewalk."

Thanks guys!
Here we usually just say "dirt road" for anything easily navigable by 2WD vehicles. I'm not aware of anything where layers of uniform gravel are laid down. What we get sometimes is an "improved surface" which means large and/rough blue metal added for traction, usually on climbs; this is very bike-unfriendly. On some fire trails sand gets added (or washed from elsewhere?) at times, also making riding tiresome/tiring.
I've seen oiled gravel roads in Norway, back in the 1980s, but nowadays I think they're either very uncommon or extinct. Back then they were an easy way to fix high or remote roads after the spring thaw, but the country was a lot poorer and less developed then too.
In more remote areas of Oz (like outback deserts) things can be a lot rougher or looser, but deserts here are mostly flat, boring and hot so I avoid them; if I'm going to make an effort to go somewhere there are more rewarding and pleasant options IMHO.
The other major class of unsealed "roads" are fire trails, typically in national parks or state forests, etc. These usually have restricted access and are not generally passble except by 4WD or bike in any case. Surfaces vary wildly, from relatively smooth and firm to sandy to rough, etc. Near Sydney it's mainly sandstone, often steep and can at times be very rough. Off-camber corners, ruts, rocks, water bars, and sand patches are all common. Soils vary elsewhere, but soft soil isn't very common, and mud is rare, fortunate since some of it is like super glue, ie the dreaded "black mud."
Re nomenclature: "Sealed" means bitumen/asphalt/concrete, while "unsealed" means some sort of dirt road, usually with little traffic and/or remote. We have neither sidewalks nor pavements next to the road here - they are footpaths(!), and riding on them is rarely socially acceptable or legal.
Based on what has been said and pics I've seen, I suspect side knobs on tyres might be considerably more useful here than on some US "gravel." I'm not so sure we have as much here where something between ~42mm with a smoothish tread and 50+mm and somewhat knobby is all that useful. One can always survive with less than optimum traction, but sometimes only just!

Stephen

https://en.wikipedia.org/wiki/Macadam
A more durable road surface (modern mixed asphalt pavement) sometimes referred to in the US as blacktop, was introduced in the 1920s. This pavement method mixed the aggregates into the asphalt with the binding material before they were laid. The macadam surface method laid the stone and sand aggregates on the road and then sprayed it with the binding material.[22] While macadam roads have now been resurfaced in most developed countries, some are preserved along stretches of roads such as the United States' National Road.
Because of the historic use of macadam as a road surface, roads in some parts of the United States (as parts of Pennsylvania) are often referred to as macadam, even though they might be made of asphalt or concrete. Similarly, the term "tarmac" is sometimes colloquially misapplied to asphalt roads or aircraft runways.

It seems that nomenclature for road types and construction probably varies with topography, geology, climate, region, country, etc. I'm not sufficiently au fait with Australian methods to say exactly how the terms align here, but a quick look at Wikipedia suggests quite a few differences. Whether these are differences in technique or naming (for paved roads) is beyond me. FWIW, road construction methods in the Himalayas are different again, and some paved main highways can be rougher than some of our dirt roads or fire trails, due to heavy vehicles, erosion, landslips, etc.
It's probably more helpful to describe the surfaces involved than just to name them, as the potential for confusion is great. Wikipedia says "asphalt concrete" is common in the USA, but I'd never encountered the term before; it looks just like "road" to me from the pictures though. Here concrete means cement, when applied to roads or bridges, and is thus light in colour, not black(top).

Cool! Do you know the eta? I asked Soma about it a couple days ago,
but haven't heard anything definitive. Was about to go with Endpoint,
but depending on max tire, this would be way preferable.

Shot some pics at the Soma Warehouse today.
