VoiceVelo Echo (aero frame)

[Bonus79]

I spoke about UCI certification with VoiceVelo yesterday - They told me that all drawings and documentation is approved by UCI. The procedure will now proceed to physical product inspection.

What do they say regarding the noise issues caused by the seatpost?

Do they plan to modify it, or is it limited to applying a layer of anti-slip paint?

Is it possible to know if there are other versions of the seatpost with different offsets and/or without the "hole"?

Thanks.

Im sorry, but i dont know anything about noise issues casued by the seatpost. I did not sell frameset to giorgio and that case wasnt consulted with me.

There are no other seatposts available.

I was understand that they were aware of the problem and had added a layer of anti-slip paint... which, according to what @giorgiobuccio wrote, didn't solve it.

The 73° listed is the effective seat tube angle (measured from the BB center to the seat clamp), but the actual seatpost angle is significantly steeper.

Ultimately, your body doesn't care about frame angles; it only cares about saddle height and saddle setback relative to the bottom bracket.
If you are on a size 58 with a high saddle extension, the seatpost follows that steeper trajectory. This means your saddle will not move as far backward as it would on a frame with a true, continuous 73° angle.

Seatpost angle (quickly measured in canva) 80°
Some gemini calculations:

Saddle Height	Inseam	Rider height	Fit Context for Size 58	Equivalent STA (Measured 80° Physical ASTA)
700mm	793mm	168-175cm	Too low for this frame. Requires minimal seatpost extension.	74.35°
750mm	849mm	176-183cm	Lower end of the fit window.	74.73°
800mm	906mm	185-192cm	Target demographic. High extension activating the steeper ASTA.	75.06°
850mm	963mm	195cm+	Extreme extension. Saddle position will shift drastically forward.	75.35°

Came to similar conclusions analysing a different frame with Cervelo S5-ish design. IMHO, with such eSTAs, the frame reach is undersized, especially for larger sizes (but I haven’t checked seatpost offset)

I really don’t think this is a widespread problem with this frame. I think I was just unlucky.

Even frames of the same model can have small differences in dimensions. If the opening in the frame is slightly larger and the seatpost is slightly smaller, the fit may be less precise and cause problems. So you can be unlucky with a particular frame and seatpost combination, while other people have no issues with the same model.

Problems around the saddle and seatpost are more common than you might expect: seatposts can slip, and saddles can tilt because the clamp doesn’t hold them properly. This is a sensitive area on many frames, including those from Western brands. It’s not something specific to this product.

At first, I received a seatpost with a smooth surface. After I explained the problem to Chris, they sent me another one with a rough, anti-slip coating to help stop it slipping. Similar solutions have also been used by Western brands.

I’m not trying to blame anyone. Unfortunately, these things happen. My case was quite bad, but we managed to fix it. I think I was simply a bit unlucky. Even very small movements can cause a lot of noise, because the hollow carbon frame amplifies the sound.

I have no idea how widespread the problem might be, but in this discussion, three or four users have experienced an issue similar to yours.

While it is true that in some cases applying electrical tape to the end of the seatpost was enough to fix it, considering we are talking about a $1,400–$1,700 frame, such problems really shouldn't occur (and let me be clear: this applies to Western-made frames as well).

So in the end, is the issue with the seatpost itself or the block that's screwed in to hold it in place?

In my case, the problem is not the seat clamp. The seatpost never slipped down, not even with the original smooth one. The issue is probably the inside of the frame: it left a very small gap that allowed the seatpost to move side to side, causing that noise.

I noticed the clamp tended to loosen over time, but that wasn't the real issue. Sometimes tightening it helped for a while, and other times it changed nothing. The only thing that actually fixed it was thickening the seatpost with extra resin.

By adding extra resin to make it thicker, the problem is almost completely gone.

Hmm, interesting. My seatpost clearance is very tight, pushing it down or pulling up is very difficult

I've been having squeaking come from Sram RD which I got fixed by getting a new RD with warranty.
