There's a new company in my hometown making CNCed aluminum + custom carbon tube'd bikes. No MTBs yet but they put out a lot of details on anything to do with these topics on their Instagram, worth a follow for the other nerds: https://www.instagram.com/frameworkbikes/

To answer the alu-carbon question, they made a story about it a while back in a Q&A. At least for them, the alu parts are plated and the bonding agent has glass microspheres that go between the tube and the lug so there isn't any carbon touching aluminum. 

They also did a repair on a proto bike with superlight tubing that had broken and basically just cooked the lug until the glue melted and pulled the tubes out. After a bit of sanding inside to get everything clean they just repeated the same process as usual. 

They have also said that 3D printed titanium is super expensive and not as good structurally as CNC'ed parts, but that explanation went a bit over my head with engineering and physics. Maybe it's not as good as CNC but those Atherton bikes have been hucked and still seem ok. The expense isn't surprising as it seems like Atherton Bikes has some big financial backing and is maybe looking to prove themselves before going cash positive (though I have no information to back that up) and maybe the alu prototype is a way to get there. Also maybe aluminum all around just to make it as freeride/bikepark friendly as possible? Even if an equivalently strong carbon tube isn't a big price difference to an aluminum tube, there's still a perception in the bike industry that aluminum is more robust for bigger riding.

3D printed parts could be more porous than billet milled parts. That's one of the biggest issues I'd say, but from what I've seen it's not really a big problem, parts get filled out nicely. 

With machining it might be really hard to make some of the parts hollow (reaching inside the part with the tool and catching all the pockets) and making things really thin walled might also be a problem. 3D printed parts on the Athertons bikes are double walled where the tube is inserted, making a pocket to apply the glue, to ensure the glue covers the overlaped portion of the lug and tube completely. 

That's where sintering printed parts comes in. Gotta clear up those miniscule voids in the printed components. By how clean that headtube looks I wonder if is forged then machined.

How bout' this

-Inverted (clearly)

-39mm lowers

-147-176mm travel adjustable in 7mm increments, done internally, can only be done at Push's shop

-CNC'd CSU, that are bonded to the upper tubes using loads of good intentions

-HSC, 47 clicks

-LSC 3 clicks

-HSR, 9.7 clicks

-LSR only adjustable internally, requires several model specific tools, like a 10mm socket (you know yours is mssing) easier to send to Push

-Axle made of unobtainium, with a special 7 sided octagonal design said to increase torsional stiffness by 36.89% over previous model, with proprietary axle sizing, to fit readily available 120mm width hubs

-Its built "for life" (requires make, model, year, colour, wheel size, tire pressure specific tune, that is only approved/tuned by Push.  Currently tunes only available for 2008 Specialized Enduro SL Expert when replacing dual crown, and 2023 Banshee Titan when ridden in mullet configuration, with anodized black frame colour)

-Doesnt require HBO, cause its got NBC* engineering

 

Let me know if I missed anything.....

Oh yeah...

$3800USD, 4200 Euro (+VAT), dont bother asking for $CAD, (enough to buy two 38's or Zebs, with money left over for a season park pass)

 

*(Never Bottom Component)

 

Unfortunately not entirely accurate.

can’t say to much but significantly less price and all mountain to enduro travel range. Also not 39mm lowers.

A lot of his opinions are unorthodox and weird. On the other hand, he actually walks the walk with his opinions: he builds what he wants, frequently from scratch and/or with extensive modification of existing components, and he rides what he builds. I can't help but respect the commitment. Lots of people talk about what kind of bike they want; far fewer make that kind of effort to create it.

Relevant? IDK. Interesting to observe? Often.

Nah, You started it here

You can make it lighter, it looks great (IMO), you can "tune" it for desired outcomes, and make it much shorter than a traditional stem and h-bar.

I dont run one, and dont want one, but even a dullard like me can see the benefits, even if it has drawbacks

Fox was having riders test a new damper last year. Maybe updated grip 2 (grip 3?) and trickling down the old grip 2?

If my memory serves vaguely right, Taj or Jordi mentioned in a Dialed video that there was gonna be a drop-in upgrade for the Grip Dampener. When they were doing bike checks, Taj mentioned he was running the new dampener. 

Is it time for an all-new fork design? Even if it was, companies like Fox and SRAM are sitting on mountains of products. It's getting to the point where some manufacturers are actually considering scrapping existing inventory to make way for new stuff. Sad really.

Whatever it is, I'm glad it can be dropped into a Marzocchi (assuming that isn't also a new chassis that isn't backwards-compatible for some reason).

I wouldn't be surprised if they are getting rid of all the old Grip 2 dampers by upgrading all the Marzocchi stuff. That HSC adjuster looks new, but the Grip 2 HSC only has 6 clicks of adjustment and would almost be better off having a rotary dial like that. Possibly they just added a new looking adjuster for the Zoke's to clear out a bunch of old Grip 2's, so Fox can drop the new stuff. Kind of KTM group-ish methinks (KTM, GAS GAS, Husqvarna on very similar but 'different' moto equipment)

Wouldn't that be a heck of a sales pitch for both brands? Zokies with Grip 2's and Fox with the new new. OOH WEE!

Why would you put a dampener in there, who wants the fork to get wet?

   I don't know why but the inverted Push fork is a real thorn in my ass--the overly vague details and utter lack of showcasing *any* performance data (to indicate value over traditional mtb fork designs) is what really twists my nipples about the whole thing. 
Here's the spec. scoop (w/picture evidence) on the USD Push fork;

-37mm or 38mm stanchion tubes 

-50mm upper tubes

-15mm axle (20mm may have created lower leg stiffness issues causing less favorable flex patterns--or the 15mm axle is actually a performance hinderance that's truly meant to soothe the 'main stream' retarded-guy consumer, lets be honest here. For no reason other than folks might have to build a new wheel with proper 20mm hubs, or worse yet. . . .swap in 20mm endcaps+axle if your hub allows//Big whoop) 

-130-160mm travel (anything 170mm+ likely has major performance drawbacks on USD single crown forks)  

-2,500-2,800g finished weight (Fox 40's are ~2,800g, RS Lyrik ~2,000g, Zeb/38's @~2,300g)   

[the added weight will actually be a performance benefit to help keep the fork consistent] 

-$2,200-2,600 retail tag 

     . . . . . . . . . . .

     //evidence

Manitou Mezzer: 37mm tubes


Intend inverted: 15mm on the left, 20mm right

new Michelin tyre coming out in the new year - “Wild Enduro MS”

Following suit of lots of other successful tyres on the market with the 3,2,2 centre knobs and consistent side knobs

looks like a mix of DH22, Assegai and Magic Mary 👌🏼

hopefully they do them in the normal wild enduro casings and not just the racing line ones which are like 1.5kg each 😂

A lot of his opinions are unorthodox and weird. On the other hand, he actually walks the walk with his opinions: he builds what he wants, frequently from scratch and/or with extensive modification of existing components, and he rides what he builds. I can't help but respect the commitment. Lots of people talk about what kind of bike they want; far fewer make that kind of effort to create it.

Relevant? IDK. Interesting to observe? Often.

Yup, that's why I brought him up. Building and testing his ideas, and showing failure modes. 

His righteous tone is grating, but he's a nerd doing the work.

   I don't know why but the inverted Push fork is a real thorn in my ass--the overly vague details and utter lack of showcasing *any* performance data (to indicate value over traditional mtb fork designs) is what really twists my nipples about the whole thing. 
Here's the spec. scoop (w/picture evidence) on the USD Push fork;

-37mm or 38mm stanchion tubes 

-50mm upper tubes

-15mm axle (20mm may have created lower leg stiffness issues causing less favorable flex patterns--or the 15mm axle is actually a performance hinderance that's truly meant to soothe the 'main stream' retarded-guy consumer, lets be honest here. For no reason other than folks might have to build a new wheel with proper 20mm hubs, or worse yet. . . .swap in 20mm endcaps+axle if your hub allows//Big whoop) 

-130-160mm travel (anything 170mm+ likely has major performance drawbacks on USD single crown forks)  

-2,500-2,800g finished weight (Fox 40's are ~2,800g, RS Lyrik ~2,000g, Zeb/38's @~2,300g)   

[the added weight will actually be a performance benefit to help keep the fork consistent] 

-$2,200-2,600 retail tag 

     . . . . . . . . . . .

The lack of information on the Push fork really "twists my nipps" too. But I speculated ~$1k+ on their new SV shock and they surprised us all with their price point (I wouldn't call it a bargain, but it was below expectations). We may yet have hope for the fork pricing. This is a new world of deflation, probably why they haven't released yet.

To be fair they haven't realesed the product yet, so I think its justifiable to not have any information on it.

It is a growing trend in the industry though, quite a few brands are now not publishing detailed suspension data, Atherton and We are One come to mind, neither of their bikes post leverage curves, anti-squat graphs etc.
