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".
Generally alignment fixtures and measuring equipment are placed on a large precision ground slab on a precision adjustable fixture.
I've never checked if the one in my office is made of marble or another type of stone.
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.
photo looks like epoxy failure between the two materials
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.
It's usually granite yes.
Damn, this build is so sick!!! I would love to try one.
Pic of BKs bike for anyone that didn’t see the replay
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.
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.

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.
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 😜
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.
So the tube pulled out of the lug?
that screenshot is hilarious lol.
With how all the epoxy has stuck to the carbon tube, I would have to assume the epoxy failed due to galvanic corrosion which is one of the bigger benefits of using titanium and carbon or aluminum and aluminum such as Atherton are doing. With proper isolation of the aluminum with anodizing or plating then an even glue line with bond spacers a joint shouldn't fail within a year. Those epoxies are strong as hell. Maybe they need to revisit the length of lap the are using.
Good to see they're sticking with double lapped lugs on the new frame.
I'm glad the mentioned forging, I was wondering if you could cast the parts and then machine the surfaces after, but I guess getting quality high resolution casts is such a niche thing anyway it was probably just as expensive for lower quality

rocky undercover at the windrock enduro
If you watch this closely, his front wheels squirms in a real weird way right before he pulls. Maybe a rut or mud, but kinda looks maybe it was going before that case.
