It also open up the door to using other allows that are not weldable like 7075 IIRC.
Yep, but I guess a marble is still required, even if alignment will be a lot easier.
You would still need an accurate fixture for bonding (like you do for welding) but the lack of heat stress from welding and heat treatment eliminates having to align them again.

The Frameworks DH bike blows away any DH bike I have tried. I was very happy with the Phoenix and I’m a huge fan of Pivot in general. Unfortunately it isn’t comparable. The Frameworks bike, even though I set it up as a hybrid Enduro bike, is night and day better.

What did you like so much about it if you don't mind me asking?
Nico's videos pretty much sold me on buying ochains for my longer travel bikes, that's for sure.
Also, any thoughts on the lever feel of those brakes?

I don’t know how to describe it other than saying it floats over all but the most extreme chunk. I’ve said this to multiple people and it sounds ridiculous but it is almost too good in that it eats up bumps so well that I was going so fast that it was hard to hold my line.
I had planned to set it up with an Ochain and in true downhill fashion but realized that it was unlikely that I’d get a chance to use it for a few months if I did. That’s why I went with the extra parts I had in my garage.
I’ve been using Trickstuff brakes on all of my bikes for a while now. Piccolas on my XC bike, Diretissima’s on a few trail bikes and Maximas on this one and my Firebird. I’m probably not the best judge on lever feel for that reason but I love how they feel.
FWiW, I’d also say that Neko and Logan have been amazing from a customer service standpoint. I went from being a fan of his riding to an advocate because I truly believe that they truly want everyone to have the best experience possible using what they’ve designed.
Bernard Kerr just snapped the front off of his prototype Pivot at Crankworks. I couldn't see if it was the lug or the carbon.
Snapped near the head tube. Tried to triple some jumps but came up short, 50/50'd the landing. Bummed to see that. I was really hoping for him to do well here.

Granite, I would expect. Marble is too soft and chemically reactive.

Damn, this build is so sick!!! I would love to try one.

CNC alloy lug bonded to alloy tubes makes so much sense for small frame builder. Can build around easily available tubes, bond joint be slightly away from high stress area and custom geometry should still be possible if desired depending on design.
Really excited to see where this could go in the next 3-5 years.

AL 7075 doesn’t even need to be heat treated, that’s the best part.

Yep, but you can buy already heat-treated 7075-T6 tubes instead of 7005-O (or other) ones, then do all the welding, then heat treat the whole frame, then check the alignment, etc...

Do you still weld the tubes if your using a lugged aluminium design? Or do you bond or braze?

There are videos on insta which show the frame close-up. Looks like a de-bond, the curved section is intact and full of dirt. Hopefully no serious injuries, nightmare crash.

More advantages to bond (all those who are discussed recently in this thread), but Specialized uses on the Chisel (and some other frames, but can't remember which ones) a forged headtube, which can be kinda viewed like a lug, then weld the top and down tube edge to edge. That's just more industrialization-friendly.
best angle I’ve seen of it. Watching it live the case didn’t seem that bad, however from this angle, maybe not every bike would have snapped, but it was a pretty big impact.
It would have been an interesting situation if it happened during quali.
Would Pivot recalled the other proto and put their team on the old frame.. not a good look for the proto, but putting their athlete at risk is not a good look for the team either.

Saves time and labor.
Yep, we're on the same page there
Is "marble" a technical term in this context, or a typo?
It's the name in French, I translated it and just found out the real name's "frame jig".

Bonding would be the best method.
Ah. Just needs some Gorilla Glue and he will be back at the next race no problem.

7075! Which is quite good, apparently
Oh and Gee on one that has Trickstuff brakes on it:
Thanks!
Didn't watch - was this one of those impacts that would've broken any bike no matter how its was constructed? I heard it was a cased triple attempt.

Perhaps Pivot would benefit from the double lap shear design that Atherton uses.
Think this is the same frame he’s been on for a year now? That’s a lot of laps.
BTW I’m a Pivot fan and a big fan of bonded frames.
Wonder if the curved downtube is needed for assembly? Seems like it would be harder to pull apart if the tubes were angled apart.
I love being an internet engineer 😜

So the tube pulled out of the lug?
that screenshot is hilarious lol.
