Sorry Robot _ I mean Atherton has the the tech, the sizing, and Ti and AM and it’s cheaper - there was also just a little too much “fittted by hand “ which in a hitec cnc’d am world with robot (again) assembly bit too analog in a digital world. And as for the square tubes and FEA???
very close but Brooklyn had a 8spd Shimano hub in the frame. with the jack shaft chain running to a single speed hub. all the shifting was done at the high pivot location.
for downhill bike, gearbox would be the best. you can always have just one chain connected directly to the gearbox on a high pivot system. you'll also get lighter unsprung weight on the rear wheel. if pivot is experimenting, they should look the other way, to the gear box design.
This stuff is way over my head ,I just think that bikes are meant to be fairly simple beasts.I don’t disagree with progress but it’s a bike not the space shuttle.Keep it simple,one chain is enough.
In a way they are doing just that. By the looks of it, you can expect the small chain to live for a very long time without needing to be replaced. And then there's the regular chain, which functions as usual. The alternative is the usual high pivot design which still requires two chains, but they're connected to create the necessary length. It also has to go around the idler and creates unnecessary stress on that part. So really while at first glance the one chain solution seems simpler, it's really not. Of course a regular non high pivot design is still more simple than both, but then again, you'd lose out on the potential performance. Having owned a high pivot idler design before, I think this is a good solution to the common problems associated with them and actually makes for more reasonable system for the endconsumer.
What is the point of doing this? There seems to be very little or no benefit (apart from looking cool), plus dangerous as seen with Bernard Kerr's latest run where it looked like the tube(s) either snapped due to stress concentration where the lug meats the tube, (Basic engineering no no for design) or the tubes slid out of the lug, hard to tell from the race run video feed.
These bikes are like Indy cars made to race & need a lot of service & parts are constantly replaced. The more complicated & the more picots & moving parts would be a nightmare for the average person.
One of the most beautiful frames I've ever seen work of art
I dont need a DH bike but this bike makes me want one just because
So cool! Can’t wait to see the production bike!
Chris, if I had 20k, I’d pay it. It’s that beautiful. Only the Atherton comes close. Just jaw dropping. 😮
We agree!!
Then go buy an Atherton AM.200. It's way "cheaper", also a 6-bar and even has titanium 😉

Almost jaw breaking, I would say
Very interesting
Looks rad!
So much better in person
Sweet Nectar 🤙🏻KMC chain
Reminds me of the GT STS 1000 CARBON bike frames from back in the 90s beautiful machines! Art!
Yes!!! And the Lobo which we lusted over for very long!
Snap snap
How long before this bike is in production and for sale ?
I would have loved to have seen a sneak peek of a fully built one.
Head to the website there are some amazing photos of the final build.
Bernard Kerr has been riding one the last few months, and just competed at Redbull Hardline last weekend.
Check out his channel.
design notes borrowed from Brooklyn Machine Works ?

Wonder how Pivot is going to react to the BK incident 🤦♂️
What’s happens to the prototypes when the Phoenix goes into production?
Snap, crackle, pop
All the best for Bernhard, but I will cancel the order for my new Pivot, the part is dangerous
3d print the lugs like the Atherton bike.
in 8 months Taiwan will make it.

next year I hear they will add 3 more chains

The glue gave way. It’s a digital age, pictures of the aftermath are out there. Pivot clearly has some homework to do
To a healthy recovery for BK 🙏
The bike did a whole race season, off season rides and two hardlines…
sure glad its prototype as aluminum and carbon fiber do not work together..long galvanic corrosion is very bad
glass microspheres are in the bond line so there is no carbon touching the ally.
Want one now! When does it come out @loamwolf? 😅
Over engineered drivetrain.
Never heard of a jack shaft?
The research and resent performance by BK and the Pivot DH team does jive with your statement.
yep just give me a horst link and call it a day.

Mistakes are being made😢😮😂
What kind?
@@TheLoamWolfDon't feed the troll! 😂
Damn… you called it. BK just took the worst of it. Bro is lucky to be alive
