Yep, they're bo longer in "affordable" territory.

I'm French, so I grew up with Decathlon. I haven't looked at it closely, but my general understanding is 2 fold.
1. the bikes have been so popular they've been flying off the shelves, which an economist would argue means the price was too low (equilibrium pricing theory).
2. the bike is ridden by a pro team, and the team genuinely aims to perform at the highest level, so you'd expect the frame to be able to support this ambition, so they probably do spend a lot on materials and R&D. The French are often good at actual work, and even innovation, but really bad at marketing it. For example, recent interviews point to the attention they paid to frame stiffness during a sprint. Given the insane speeds at which sprints are won, and that there are countless stages where a sprint is won by less than a bike length, as sprinter will want a bike that will be very fast, and very stiff. This new frame solves for that.

So, it annoys me a lot that their bikes are now so expensive, and I would bet that this also annoys a lot of Decathlon employees & their friends, but it's also understandable. The competition is simply over pricing stuff across the board.

Given how tight a ship Decathlon has been running for decades, i'd bet their R&D costs are a fraction of the likes of Specialized, so I would bet that they could sell the frames at a much, much lower price point. But then, point #1, where the frames would just sell out all the time, and i would even expect a grey market with people selling frames they just bought in the secondary at a premium, precisely in an effort to find an equilibrium price. Because that's exactly what i'd do. If the prices were a no brainer, I'd buy frames and sell them to people abroad.

Where did you find the carbon layup of the Van Rysel. What is T40, T60 compared to 1100, 1000... ?

One of the van rysel guys mentioned that during an interview i saw on youtube. GCN one, from memory.
40/60 i think is T or M. So i think T40 is M40 or 40M. It's all quite confusing and few people really know the ins and outs of the topic, i think - and certainly not me. T in T800 is for Toray. I think the M is for Mitsubishi. But i think Mitsubishi is making Toray fibers. I understand 40T and 30T is similar to T800 and T700. But more expensive and better performance. So 60T is probably like T1000.
Anyhow, it's apparently what expensive frames are made of (the high end stuff, like Factor, Sworks, Pinarello). Giant, Merida, Cube, Orbea, all these, afaik, use lower grade stuff, probably very similar to what our OEM frames have.
Also, does any of this really matter, or is it a flex? idk. But it's probably the tricks pulled to shave the last 50 or 100g off a frame, and it's probably why you have a jump in price, because T700 & T800 is everywhere, but T/M40/60 isn't.

I've received a PM about the toolbox I have designed 3d printed for the VB-TT-023. If anyone wants the .stl file to print it yourself, feel free to download in on thingiverse:

https://www.thingiverse.com/thing:6988838

I suggest using PETG for this box, as it offers flexibility aswell as heat stability and UV resistance. Both pieces can be printed without support if you flip them to the flat side in your slicer. You'll need two M5 screws to attach it to the frame. Sadly using this toolbox, you will not be able to mount bottlecages in the frame correctly any more. I haven't found a way yet to circumvent this, but if I do I'll post a new revision.

Awesome!
Cautionary tale. 3d printed stuff tends to fail catastrophically in ways injected molded plastic doesnt. I had a 3d printed box behind my seat post on my propel, it worked until it just exploded. So, people, when you use 3d printed parts, be mindful of print orientation / layer lines, material fatigue, stress points, how to reinforce a print with non 3d printed parts like inserts, mesh and so on. Don't be like me, basically. Especially those who just DL free STLs from Thingiverse and send them to print without giving it much thought.

I'm not an expert, but i've bought a dozen OEM frames in the last 3y, and if i had to pay Winspace prices to receive that, i'd go ape shit.
Loose carbon strands in critical areas (headset & bottom bracket cups) isn't exactly reassuring. carbon fiber strands without the resin matrix have zero strength. So if the edges of the frame like that has such strands, critical areas of the frame potentially have compromised strength.
Now, that being said, you have a T47 BB, which kind of exists to allow shoddy manufacturing, which is exactly what you have here. As long as the metal shell is bonded to the frame, having loose strands around it scares me much less than if the BB were press fit. The headset bearing cups dont look pretty, but unless there's a clear oval (vs round) or a clear lip that's not of constant thickness and so on, i think you're safe.
The ugly patch in the middle of the BB area looks bad, but it doesnt look like you have big ass shards that weren't compressed like the frame we saw last week another user post. It's probably from manufacturing process, and just shows they suck.

Basically, if you look at the inside of the fake Ostro frames on this forum, and at these 2 winspace frames, i know who i'd work with... The level of irony in the fact sellers of fake products have products that look 10x tighter than Winspace...

Patlean mentioned that winspace may be struggling financially from supporting a racing team and being burdened with out of date wheels. that would make sense, and i would expect them to cut corners.

I'd stay away from that brand, because you pay a LOT more than what competitors offer (all over this forum), but they treat you like a$$ if you complain. And they have the audacity to say this is normal to receive such frames at the price point, so why take that trade? For anyone wanting to spend winspace territory money, i'd consider at the fake Factors on the thread here, and get it without a logo. Or get Peter's upcoming Gran Turismo frame, because it's likely going to be a similar price point with T1100, 40T, 30T fibers. The new van rysel aero frame uses T1100, T40 and T60, similar to the real Factor frames, so we're talking high end stuff. Much higher end than Winspace, btw.

I can compare it at least to my SL7 on which I have 120.000 km

Btw so can someone confirm me that it is compatible with front 140 mm disc rotors?

Will be very curious to hear your thoughts on how the 2 frames compare, given you're pushing equipment in ways that 90+% of the users on this forum dont.

Does anyone know where you can get Juin components from (as close to source as possible?)

If you are looking to buy several sets, probably at least 5, then you'll find cheaper prices on Alibaba easily, but then you have to figure out shipping, and Aliexpress has incredibly cheap shipping (a lot of what you pay on aliexpress is shipping, when they say free shipping, you're obviously paying for it in the price).
If you just need one set, realize that they don't need your business, so even if you talk to an employee there, you're not magically going to get a great deal. In fact you're likely going to pay more, because aliexpress resellers get wholesale prices themselves.

One good thing on Alix that you dont have on bang good, for eg, is competition. bang good sells one product from one seller, and therefore prices tend to be high. Alix is a free for all, including scammers, so there's much more competition, driving prices down. Jack Ma created the whole thing literally to create a tool to allow anyone to sell anything.

would you buy a car based on how easy it is to open the trunk?
Such an odd way of choosing a tyre, given it's the only thing that connects you to the ground. Would you buy bad rubber over good rubber, all else equal, because it's (allegedly) easier to install?
