it would also be easier (and cheaper) to get protos made with lugs and carbon tubes before having to commit to a full tooling
Very interesting headtube zone if this is in fact lugged.
I don't think so, based on how wide the chain gets around the rear axle, looks like it's going through a derailleur.
looks like the old Six-13 road bikes from Cdale. They would put an uncured carbon tube into an alum lug that had cutouts. then inflate the bladder to get the tube to mold into the cutout. would create a mechanical bond as well as the chemical bond from the glue. very interesting way of doing it and worked great for those road bike 18 or so years ago.
And a bent tube will move the 'inline' forces (pulling the tube and thus joints apart) effectively off-axis, potentially making the bonded joint stronger.
Also, if I was a betting man, I would bet against this being a standard DW link bike. Maybe DW6. It looks kinda Horst link to me (thus the DW6 caveat).
GT did something similar with the STS, LTS and the Lobo. And even used thermoplastic resin instead of the epoxy mostly used these days (thermoplastic composites have much better recyclability).
I was mostly wondering because the bottom bracket/seat tube area looks massive, even compared to most high-pivot bikes
The more I look at it it sure looks like a fully aluminum frame with a sneaky paint job. Check out how the top tube is tapered and shaped.
My guess would just be vinyl wrapped alu. Didn't the Trek team in 2021 black out their top tubes on those candy metallic frames after the first few races? Top tube reflections could be a real problem on raw alu.
Top tube reflections might be a problem on a highly polished raw alu bike. Anything else will look as dull as a foggy morning when it comes to raw alu. Look at Neko's frames for example.
Plus, if you see your top tube, aren't you doing something wrong. Holding back too much or riding a bike 3 sizes too big? (not to mention the flashes from the photographers...)
Do we know who's riding it or where its being ridden?
Any other photos of it?
Being ridden in Queenstown nz
Given the chain angle coming from the chain-ring area...
I think they are not using that upper sprocket as an idler pulley, but rather as a drive sprocket. Thus, either is IS a gearbox (unlikely due to chain angle towards rear wheel) or some sort of one-to-one gearbox (a drive-extender?).
What I WANT it to be is a gearbox bike with a redundant cassette on the rear wheel to throw people off.
Here’s a photo of DW’s high pivot patent design. Not a gearbox…
It is definitely exactly that, thanks for including the image
I am the example of someone who should have read the last page or two of the thread before posting
One of the benefits of the new DW patent that I haven't heard mentioned yet is the super small front chain ring. Because the gearing steps down twice (from the first drivetrain to the second), the bike can get away with a really small chainring and a ton of ground clearance while still having the same final drive ratio.
I was on a ride on Friday where I dragged my bashguard 4-5 different times. Would not mind more ground clearance.
taking bets on when that photo will be ripped and used on the other site..... 1 day, 2 days....
My first suspension bike was an XL polished Heckler and top tube glare was NEVER an issue.
since some in here love to sh* on pinkbike that all they do is steal from this thread, check out their newest post, new ibis enduro proto.
haven‘t seen it in here yet
Funny, how it's totally ok when people post stuff in here that has first been reported by PB (or posted on the PB forums), but if PB reports something that was here first it's them "stealing" content. It's not like it's yours anyways, so why would you even care...

New RAAW DH Bike!
Edit: damn. iceman2058 beat me to it.
Not important apparently 😜
here's 30 mins of details about the RAAW yalla
Full 29 only even for the M sized frame is a bit questionable IMO, but I guess their shorter riders did not have any troubles with it. Nothing crazy going on geometry wise with competitive modern numbers, although I'd like for brands to go with a 460 mm base reach for M frame (based on my experience as a medium sized person at 175 cm tall on a M Canyon sender which feels like it was tailored made reach-wise).
Cannondale had the non-high pivot version back in 1998.
Supposedly the main advantages and design goals for the new DW patent is for the dreaded e-bike. Seeing how Pivot has a huge boner for e-bikes these days, this is likely just testing the concept and it will be plugged into a bike with a motor, not a DH bike....
At least it's very adjustable.
But I'm glad the geometry is the way it is. There's surprisingly little choice for tall people like me, who wants 500 mm of reach at the very least.
Fantastic. I could listen to Dan Roberts talking nerdy all day.
More ground clearance? Sounds like a perfect job for IMBA, not bike engineers.
It is the same size as my medium Madonna, and I would say the full 29 is excellent. I'm not a small person, I am decidedly "medium" at 177cm which is the low end of the large, high end of the medium Madonna recommendations. I feel like it is very well balanced, I don't buzz myself except on the steepest drop ins, and it turns incredibly well.
Because Ibis sent them the photo after the DV9 release flopped.
Take a look at their newest newest post. Two week old spy video of Jack Moir riding the new rockshox vivid air.
